These vertical suction filters are designed for installation between the pump and reservoir tank. Their main function is to protect the pump.
No air pockets There are no places for air pockets to form. This prevents damage to the pump and enables normal operation to start immediately.
Elimination of all collected matter All collected matter can be disposed of reliably when the element is replaced. There is no dan-ger of collected matter dropping back into the tank.
No drain port required The structure of the filter does not contain areas for drain fluid to collect, so there is no need to manually drain the pump.
Easy element replacement Simply open the cover to quickly replace the element without touching the pipes. The ele-ment is extracted from the top, so no fluid can leak out.
Compact and lightweight The compact and lightweight design employs an aluminum casted housing.
Clogging sensor The sensor indicates when the element is be-coming dirty, facilitating maintenance and help-ing to avoid pump damage such as cavitations. Differential pressure indicator/two-stage indica-tor, reset type Differential pressure indication switch/visual combined, non-reset type

qMounting
• Confirm INLET and OUTLET before connect-ing.
• For maintenance, make sure to provide suffi-cient space above the filter for removing the element.
wOperation
• Operation of the differential pressure indicator in cold weather, such as during winter, mostly occurs due to high viscosity, so check wheth-er it is from clogging or not after normal oper-ation starts.
• If the differential pressure indicator is the re-set type, make sure to reset it after normal operation starts in cold weather such as dur-ing winter.
• When using a differential pressure indication switch, if a filter clogged signal is incorpora-ted into the sequence circuit of the machine, make sure to design the system so the filter clogged signal does not operate until normal operation starts.
eElement replacement
• When the pressure difference reaches 20 kPa during filter operation (actuating the differen-tial pressure indicator), stop operation and either wash or replace the element.
• During disassembly and assembly, check that there is no cracking of or damage to the O-rings.
• When washing the element, do not wipe it us-ing a stiff brush or rag.
• After washing the element, make sure the base seal is properly mounted.
Compact and lightweight The compact and lightweight design employs an aluminum casted housing.
Prevents pump cavitation The inlet size is larger than the outlet size to prevent pump cavitation.
Easy element maintenance Simply open the cover to detach the element without touching the pipes.
Easy-mounting pipes There is no mounting orientation, and two types are available: threaded and flange.
Accessories available for a variety of applications Available accessories include differential pres-sure indicators (differential pressure indicator or differential pressure indication switch), relief valves, and companion flanges.
Clogging sensor The filter can be fitted with a differential pres-sure indicator (two-stage indicator, reset type) or differential pressure indication switch (visual combined, non-reset type).
Note) The material of the O-rings and seals differs depending on the hydraulic fluid used.�Petroleum, Water-glycol, Emulsion: NBR; Phosphoric ester: FKM, EPDM

Suction Filter with Case Series FH99
Designed to prevent collected dust from falling into the tank All collected dust can be disposed completely when the element is replaced. There is no dan-ger of collected matter dropping back into the tank.
No need to replace flushing oil Since all dust is eliminated during trial opera-tion, it is not necessary to replace flushing oil. This reduces both labor and wasted oil.
Easy maintenance and no air mixing No special tools are required for maintenance, and insertion-type element replacement is quick and easy. This helps prevent air mixture into the suction line and pump damage.
Compact tank equipment The lubrication port strainer, suction filter, and air breezer are all integrated into a single unit, reducing the volume of equipment around the tank.
Selection of connection methods and accessories for a variety of applica-tions Six methods are available as standard. Differ-ential pressure indicators (visual and switch) are available and can be selected to match the application.

wOperation
• Operation of the differential pressure indicator in cold weather such as during winter mostly occurs due to high viscosity, so check wheth-er it is from clogging or not after normal oper-ation stars.
•Once the differential pressure indicator is trig-gered, the indication continues to be dis-played until the indicator is reset (by depress-ing the reset button), even if the pump stops operating.�Reset after replacing the element and restart-ing operation, or after normal operation starts in cold weather such as during winter.
• When using a differential pressure indication switch and if a filter clogged signal is incorpo-rated into the sequence circuit of the ma-chine, make sure to design the system so the filter clogged signal does not operate until normal operation starts.
eElement replacement
• When the pressure difference reaches 24 kPa during filter operation (triggering the differen-tial pressure indicator), stop operation and either wash or replace the element.
• When replacing the element, check the O-rings and replace them if they are damaged.
• When installing and removing an element, do not scratch or damage it by touching the cor-ners of the case, etc.
• When washing the element, do not wipe it us-ing a stiff brush or rag.
rRemoving the element
• Rotate the air breezer (cap) one-third of a turn counterclockwise and remove it. Grasp the handle of the lubrication port strainer inside and, while rotating it clockwise, pull it up verti-cally. The suction element is screwed onto one end of the tension bolt and along with the lubrication port strainer, can be removed and installed freely. Do not remove the suction ele-ment while the pump is operating.
• The product is shipped from the factory with the maximum T dimension, so the user must adjust it to the required T dimension.
• The T dimension adjustment range, relative to the standard T dimension, is ±30 mm for 1/2B to 1B and ±45 mm for 1 1/4B to 2B. The dimension for ±30 mm for 2 1/2B to 3B is fixed, so no adjustment is possible.
• Refer to the operating manual for details of the adjustment method.
yLubrication
• Remove the air breezer (cap) and lubricate through the lubricatioin port strainer. Be care-ful not to let oil, etc., get onto the cap while it is being removed.
Handling Precautions
qMounting
• The portion of the suction guard below the oil tank mounting flange is installed inside the oil tank, so check to make sure it is clean when mounting it. For maintenance, make sure to provide sufficient space above the filter for re-moving the element.
• Use caution to ensure airtightness when con-necting an outlet and installing a differential pressure indicator (especially for the thread type).
• Ensure that the oil tank fluid volume (mini-mum fluid level MIN(r) dimension) is 30 mm for 1/2B to 1B, 60 mm for 1 1/4B to �1 1/2B, 80 mm for 2B, and 120 mm or more for 2 1/2B to 3B, measured when there is no turbulence in the flow from the element open-ing or fluctuation in the fluid level. Also, select a T dimension (length below flange neck) that will ensure that the fluid level does not reach the lubrication port strainer.

Suction Guard Series FHG
Compact, solid, and safe design The case and cover have undergone testing in which they were subjected 100,000 times to im-pacts equivalent 1.5 times the rated pressure (confirming to MIL standard).
Easy element replacement The element is extracted from the top, and se-cured in place by inserting an O-ring seal. The element can be installed and removed easily, simplifying maintenance.
Reliable outlet side A firm seal is secured through a special config-uration combining a pressure clamp from an O-ring around the inner perimeter of the case with support from the cover, and there is no resis-tance when the cover is installed and removed.
Large drain exhaust port The large M24 drain exhaust port assures rapid drainage.
Easy fluid flow direction reversal Simply turn the cover 180° relative to the casemounting base to reverse the fluid flow direc-tion.
Clogging sensor The filter can be mounted with a differential pressure indicator (two-stage indicator, reset type) or differential pressure indication switch (common with visual, non-reset type).
Note) Tapered female thread connection conforming to JIS B 0203 is compatible. �Flanges conforming to JIS B 2291 (21 MPa piping flanges for hydraulic use) SSA are compatible.

Two indication methods are available: differen-tial pressure indicator and differential pressure indication switch. These can be mounted on all filter models.
• Operating pressure—0.275 MPa
• Once a value is displayed, it will continue to be displayed until reset, even if the pump is stopped. (2-stage display reset type)
• Perform element replacement when the red ring floats up and covers the entire view port.
L Differential pressure indication switch • Operating pressure—0.275 MPa
• When a value has been displayed, it will be automatically reset when the pump is stopped. (Non-reset type)
• This is a visual dual-purpose 2-stage display. Perform element replacement when the switch has actuated (when the red ring floats up and covers the entire view port).

Differential Pressure Indication
qMounting • Confirm INLET and OUTLET before mount-
ing. Then connect so that the drain is orien-ted downward. For maintenance, make sure to provide sufficient space above the filter for removing the element.
wOperation
• Operation of the differential pressure indicator in cold weather such as during winter mostly occurs due to high viscosity, so check wheth-er it is from clogging or not after normal oper-ation starts.
•Once the differential pressure indicator is ac-tuated, the indication continues to be dis-played until the indicator is reset (by depress-ing the reset button), even if the pump stops operating.�Reset after replacing the element and restart-ing operation, or after normal operation starts in cold weather such as during winter.
• When using a differential pressure indication switch and if a filter clogged signal is incorpo-rated into the sequence circuit of the ma-chine, make sure to design the system so the filter clogged signal does not operate until normal operation starts.
eElement replacement
• When the pressure difference reaches 0.275 MPa during operation (actuating the differen-tial pressure indicator), stop operation, drain the oil from the case, and replace the element.
• When replacing the element, check the O-rings and replace them if they are damaged.
• When installing and removing an element, do not scratch or damage it by touching the cor-ners of the case, etc.
rOthers
• For the top cover O-ring, use a product of hardness 90 to prevent leaks or damage.
• If there is back pressure, install a check valve on the outlet side to prevent damage to the element.
• Turn the top cover 180° to reverse the oil flow direction.
• Use an auxiliary pipe or the like and apply force evenly when tightening the cap screws on the cover and case.

Vertical return filter
Oil tank
M
Machine
The vertical return filters are designed for mounting directly on top of oil tanks for hydraulic systems. They prevent dust generated within the circuit from entering the tank and help keep the oil clean. This efficient configuration reduces the total number of filters required.
Compact design that does not clutter the top of the oil tank Since most of the filter case is inside the oil tank, very little space is occupied on the top of the tank.
No need for an OUTLET pipe The filter case also functions as a fluid return pipe, so there is no need to attach a separate OUTLET pipe.
Easy maintenance Simply open the cover and extract the element from the top of the filter. Replacement is quick and easy.
Designed to prevent collected dust from falling into the oil tank The collected dust remains inside the element, so it cannot flow out when the relief valve is opened and all collected dust is removed from the case.
Two INLET ports The filter has two INLET ports, oriented 180°from each other to provide more flexibility when routing pipes.

qMounting
• Confirm the INLET orientation before mounting. Then connect so that the case is oriented down-ward. For maintenance, make sure to provide sufficient space above the filter for removing the element.
• The filter has two INLET ports. If one is not used, it must be covered with a plug or the like.
• Before mounting the filter on the oil tank, confirm that r the O-ring (see “Construction”) is installed on the body.
• Ensure that the opening in the case (OUTLET) is always below the fluid surface. Air could leak into the system if the fluid level drops below the out-let opening.
wOperation
• Operation of the differential pressure indicator in cold weather, such as during winter, mostly oc-curs due to high viscosity, so check whether it is from clogging or not after normal operation starts.
•Once the differential pressure indicator is trig-gered, the indication continues to be displayed until the indicator is reset (by depressing the re-set button), even if the pump stops operating.�Reset after replacing the element and restarting operation, or after normal operation starts in cold weather such as during winter.
• When using a differential pressure indication switch and if a filter clogged signal is incorpora-ted into the sequence circuit of the machine, make sure to design the system so the filter clog-ged signal does not operate until normal opera-tion starts.
eElement replacement
• When the pressure difference reaches 0.18 MPa during filter operation (actuating the differential pressure indicator), stop operation, and replace the paper element or wash the micromesh ele-ment. If the micromesh element has reached the end of its service life, replace it.
• When replacing the element, check the O-rings and replace them if they are damaged.
• When washing the micromesh element, do not wipe it using a stiff brush or rag.
Note) The non-standard filtration is for micromesh elements only. Refer to page 32 for details.

Reset button
Two indication methods are available: differen-tial pressure indicator and differential pressure indication switch. These can be mounted on all filter models.
L Differential pressure indicator • Operating pressure—0.13 MPa
• Once a value is displayed, it will continue to be displayed until reset, even if the pump is stopped. (2-stage display reset type)
• Perform element replacement when the red ring floats up and covers the entire view port.
L Differential pressure indication switch • Operating pressure—0.13 MPa
• When a value has been displayed, it will be automatically reset when the pump is stopped. (Non-reset type)
• This is a visual dual-purpose 2-stage display. Perform element replacement when the switch has actuated (when the red ring floats up and covers the entire view port).
• N.C. and N.O. common
Differential Pressure Indication
qMounting • Confirm INLET and OUTLET before mount-
ing. Then connect so that the case is oriented downward. For maintenance, make sure to provide sufficient space above the filter for re-moving the element.
wOperation
• Operation of the differential pressure indicator in cold weather, such as during winter, mostly occurs due to high viscosity, so check wheth-er it is from clogging or not after normal oper-ation starts.
•Once the differential pressure indicator is ac-tuated, the indication continues to be dis-played until the indicator is reset (by depress-ing the reset button), even if the pump stops operating.�Reset after replacing the element and restart-ing operation, or after normal operation starts in cold weather such as during winter.
• When using a differential pressure indication switch and if a filter clogged signal is incorpo-rated into the sequence circuit of the ma-chine, make sure to design the system so the filter clogged signal does not operate until normal operation starts.
eElement replacement
• When the pressure difference reaches 0.13 MPa during operation (actuating the differen-tial pressure indicator), stop operation and re-place the element.
• When replacing the element, drain the fluid from the case. Also, check the O-rings and replace them if they are damaged.
rOther
• Refer to the operating manual regarding the tightening torque for clamping ring.

These magnetic separators protect machinery from malfunctions, reduced precision, and burnout by adsorbing and eliminating contaminants in the fluid by means of magnetism. This helps extend the service life of hydraulic equipment.
Zero running cost Since there are no consumable parts, the run-ning cost is basically zero and the magnetic separator can be used semi-permanently.
Extends service life of hydraulic fluid By adsorbing and eliminating contaminants, the magnetic separator retards deterioration of the hydraulic fluid and makes it possible to extend the fluid replacement time.
Reduced maintenance costs The magnetic separator prevents mechanical problems caused by contaminants such as abrasive particles and greatly reduces mainte-nance costs.

Mounting q The flat portion of the stainless steel cover functions as the con-
taminant adsorption surface. However, for FHMl-055, the flat por-tion of the magnetic material functions as the contaminant adsorp-tion surface.
w Mount the magnetic separator in a location where fluid is constant-ly flowing by in laminar flow.
e Avoid locations such as near the suction pipe or return pipe, pla-ces where there is turbulence, and locations where the flow speed is 3 m/min or greater.
r If necessary, fix the separator in place. If frequent cleaning will be necessary, it can be suspended from the top panel of the tank.
t If a fluid switch (built-in lead switch) or the like is used, it should be installed in a location where it will not be affected by magnetism from the separator. (Refer to the technical data sheet (SM-82-006) for information on magnetic fields.)
Maintenance q Clean the separator regularly. Make sure to clean it once the accu-
mulation of contaminants reaches a thickness of 20 mm or so. w Clean the adsorption surface of the separator by wiping away the
accumulated contaminants using a soft rag or the like.
Handling q Do not bring the top surface of the separator near magnetically at-
tractive objects such as iron plates. w Handle the separators individually and do not bring them into close
proximity with each other. e Be careful not to get your fingers caught between iron plates, etc.,
when installing the separator. r Do not bring objects that are affected by magnetism (cards with
magnetic strips, watches, etc.) near the separator.

Series FHSpecific Product Precautions Be sure to read this before handling. Refer to the back of page 1 for Safety Instructions.
Design
Caution1. Do not use at a pressure that exceeds the
operating pressure range. 2. Do not use at a temperature that exceeds
the operating temperature range. 3. Fluid
Do not use the product with gases. Do not use fluid other than hydraulic fluid.
4. Fatigue damage Under the following conditions, special measures are re-quired: 1. If the product will be subjected to pressure surges. 2. If the product is not mounted securely and will be subject to
friction or vibrations.
5. Corrosion The product may corrode depending on usage conditions and environment.
Selection
Warning1. When selecting products, carefully consider
the usage purpose, the required specifica-tions, and the usage conditions (fluid, pres-sure, flow rate, temperature, environment), and ensure that the specification range is not exceeded.
2. The fluid used must not be heated to the boiling point.
3. Do not use the product with air or other ga-ses under any circumstances.
4. Do not use the product in circumstances where it will be exposed to pressure that ex-ceeds the rated operating pressure range, such as with a water hammer or surge pres-sure.
Fluid
Warning1. Do not use fluid other than hydraulic fluid.
Piping
Caution1. Make sure to allow sufficient space for
maintenance when installing and piping. 2. Connections
Make sure no cutting chips from pipe threads or sealing ma-terial gets inside the piping. If sealing tape is used, leave 1.5 to 2 thread ridges exposed at the end of the male thread.
3. Filter installation Use stays or the like to secure the inlet and outlet pipes so that the filter unit is not subjected to external force such as vi-bration.
Operating Environment
Caution1. If the product is used in an environment or
location conducive to corrosion, discolora-tion or deterioration due to corrosion may occur.
2. Fatigue damage may occur if the product is used in a location subject to vibrations or impacts.
Maintenance
Caution1. The differential pressure will increase if the
filter becomes clogged with foreign matter. The differential pressure indicator operation pressure is the pressure difference at which the element should be replaced. When the pressure difference rises to this level, replace the element with a new one. A differential pressure indicator and differential pressure indication switch are available as op-tions.
