FFU SeriesFAN FILTER UNITSThe FFU Series of fan filter units are specifically designed to provide clean, unidirectional supply air at controlled discharge velocities for cleanroom, pharmacy and laboratory applications. These units come standard with many useful features and can be customized with standard or special options to suit virtually any project.

Fan powered diffusers with integrated high efficiency filters for critical applications requiring additional static pressure boost.

Fan Filter UnitsFFU Series

Product Information

Price FFU Series modules consist of a fan/motor assembly and high efficiency HEPA/ULPA filter. The modules are designed to provide filtered, unidirectional vertical air flow over a cleanroom space. Price fan filter units are recommended for use in all types of cleanroom environments – semiconductor and microelectronics manufacturing facilities, as well as pharmaceutical and medical labs. The product is designed for use in Class 10 through Class 100,000 cleanroom spaces.

High capacity (FFU-HC) units offer the largest active filter area and the highest air flow capacity of all Price fan filter units. Removable filters allow for periodic filter changes (filter removal and replacement requires access to the ceiling plenum), and an expanded metal mesh screen protects the filter media from inadvertent damage during installation. Filter face is PSL tested post-assembly.

Room-Side-Removable (FFU/FFUSS) units offer the convenience and flexibility to periodically replace filters from the room-side of installed modules. All RSR units are PAO tested to ensure the knife-edge frame is completely sealed. Filters are latched in place such that the continuously welded knife-edge is embedded into the filter gel seal, creating a leak-proof barrier. Additional benefits include optional room-side removable motors and 3/8 in. NPT aerosol injection ports. Once installed, the filter is protected by a perforated face that is secured to the main assembly using quarter-turn fasteners.

ECM motor technology is an available option on all Price fan filter units. Key benefits of these motors include:• Lowerenergyuse.• Loweroperatingtemperatures.• Programmed to deliver constant air

volume, independent of filter condition.

Features• Quietoperation-Highefficiencysound-

absorbing foam liners and Motors mounted with vibration isolators.

• Non-ductedmodulesareETLcertifiedtoUL507 standard.

• Ducted modules are ETL certified toUL1995 standard (with optional plenum rated polymer foam insulation).

Filter Retainers• Four(4)thumbwheel

retaining latches hold the filter in place and allow for easy filter replacement without the need for tools.

• Uniqueadjustablelatchdesign does not penetrate the knife-edge, further reducing the risk of leaks.

* To determine Air Flowrate in CFM, multiply operating range velocity (fpm) by the filter face area, (2x4 = 5.04ft2, 2x3½ = 4.31ft2, 2x3 = 3.59ft2, 2x2 = 2.13ft2) do not select at high velocity end as it is rated with clean filter only.

It is not recommended to have a filter face velocity exceeding 140 fpm. Above this point filter efficiency decreases.

FFU-HC Performance Data

Performance

Average velocityThe unit will provide filtered air at an average velocity of 90 FPM (+/-15 FPM).

FFU Performance notes:1. Units are tested in accordance with IEST

RP-CC002.2, Recommended Practice for Unidirectional Flow Clean-Air Devices.

2. Sound levels were measured with unit installed in a T-Bar ceiling, with gasket, in a standard room. Sound levels in dBA were measured at a distance of 30 inches from the filter face, with the unit set to produce 90 fpm average face velocity. (Note that data is for a clean filter only. If fan speed is increased to compensate for filter loading the noise level will increase.)

3. Amp and Watt ratings are based on a unit with a clean filter.

4. Max Static Pressure - The maximum static pressure drop in inches w.g. pro-duced across the unit while maintaining a face velocity of 90 fpm at maximum motor speed.

FFU-HC Performance notes:1. Units are tested in accordance with IEST

Electronically Commutated Motors (ECM) are optional on all FFU Series modules. These brushless DC motors include a built-in inverter and microprocessor-based motor control. The ECM motor includes several features that make them superior to conventional electric motors:• Factorysetfanflow• Energyefficientoperation• Longmotorandfilterlife• Programmable• Wideoperatingrange• Lowheatgeneration• Quietoperation

As filter pressure increases with use, the ECM motor automatically compensates with increased speed to maintain a constant flow of supply air.

ECM Technology

Options

Ion Bar OptionIon bars are easily fastened to the FFU perforated face and provide ionization to help statically neutralize the air and work surfaces serviced by the FFU.

Many industries use ion bars as a portion of their defense against electrostatic discharge damage to sensitive electronic components.

DescriptionThe Price Universal Speed Controller provides variable speed control of permanent split capacitor (PSC) motors used in Price fan filter units.

The USC is a solid state device with integral heat sink/mounting plate. This results in a long life component that is easy to install.

WiringThe connection is 2-wire (no-polarity). The USC is connected in series with one of the motor lines. (Typically the hot).

SetupThe USC is factory calibrated for the fan filter unit it is installed on. This means the minimum adjust dial has been set to a specified voltage. The user adjust dial can then adjust the motor speed between minimum and maximum speed.

NotesWhen measuring the voltage output from the speed controller you must use a TRUE-RMS volt-meter. A non TRUE-RMS volt-meter will give inaccurate readings due to the shape of the AC waveform coming from the electronic speed controller.

It is not recommended to change the minimum adjust dial since running the motor at lower speed may reduce its life due to overheating the windings and stressing the shaft bearings. (Low RPM prevents lubrication of the bearings).

DescriptionThe Price ECM speed controller is specifically engineered to interface with a high-efficiency ECM motor. This low voltage speed controller offers either full manual control (VIA an on-board dial), or BAS (building automation system) control of the ECM motor. Switching between the two modes is easy: just apply the BAS signal and the controller will automatically switch over from manual (dial) mode to BAS mode.

Features

• Lowsupplyvoltage(24VAC).• Dual outputs to control up to 2 ECM

motors.• FrontfacingGreenDiagnosticLED–for

easy troubleshooting.• On-boardmanual adjustment dialwith

front facing voltage taps for voltmeter hookup (no need to open electrical enclosure).

• BuildingAutomationSystem(BAS–2to10 VDC) input for variable speed remote control.

Diagnostic LEDThe Diagnostic LED blinks out the current status of the board. This information is used to determine if the speed controller is operating in Manual (Dial) or BAS (Building automation system) mode and if the current setting is OFF or CONTROL. Note: The Diagnostic LED repeatedly blinks out the sequential status code followed by a pause.

• 1Blink–ManualOffMode• 2Blinks–ManualControlMode• 3Blinks–BASOffMode• 4Blinks–BASControlModeBuilding Automation System (BAS) InterfaceThe BAS interface accepts an industry standard 2-10 VDC signal from a controller or computer to vary the speed of the ECM motor. This allows remote control/shutdown of the ECM motor based on air requirements and/or occupancy modes. Note: turning off 24 VAC power to the ECM speed controller will turn off ECM motor.

• 0-1VDC BAS input – Manual Mode• 1-2 VDC BAS input – BAS Off Mode

(recommend sending 1.5 VDC to turn off motor)

• 2-10VDC BAS input – Modulating control (0 – 100%)

DescriptionThe Price Deluxe ECM speed controller works with a high efficiency ECM motor. This low voltage (24 VAC) speed control allows full manual (push button adjust) or BAS (2-10 VDC signal) control of the ECM motor.

Features:

• Dual outputs for controlling 2 ECMmotors (Note: Both motors will receive the same signal.)

• Red three-digit digital display forreading out:

a) Speed 0-100% b) Motor RPM (for motor number 1 only) c) BAS input voltage (Digital readout of

incoming BAS voltage signal.)• Building Automation System input

(2-10 VDC) for remote control

LED Digital Display The Digital Display shows the user several modes of operation. This allows for easier and more precise field adjustment and troubleshooting.

By pressing both the UP and DOWN push buttons at the same time the user can cycle between the following modes:

1) Speed Adjustment – is easier and more precise with the digital display and push buttons than with a standard dial.

2) Motor RPM – displays the real time motor speed to aid in troubleshooting.

3) BAS input voltage – displays the input voltage signal from the building automation system (BAS). Note: any BAS voltage signal above 1 VDC overrides local speed control.

Important Information Regarding the ECM MotorDo not switch 120/208/240/277 VAC power to turn ECM motor on and off. Instead control the 24 VAC signal or BAS signal to turn the ECM motor on and off. The ECM motor has large capacitors that charge quickly on mains power up. Switching on several motors frequently could reduce building power quality and is not recommended.
