Super-slimline, aesthetic, low-noise, fast assembly and high output.

These are the distinguishing features of the super-slimline fan-and-

filter units. The requirement for use is that the ambient temperature

must be below the enclosure internal temperature. The enclosure

interior is cooled via the inflow of filtered external air and the dissi-

pation of heated enclosure interior air.

Practical example of a fan-and-filter unitFan-and-filter units are used in virtually all segments of industry: from the smallest enclosures, to command panels and con-soles, through to large and bayed enclo-sure systems. They are the easiest method of protecting against overheating and hot spots.

The basic pre-requisite for use is that the ambient temperature must be significantly below the enclosure internal temperature.

A wide range of control units such as ther-mostat, hygrostat and speed control for noise minimisation extend the applications e.g. to include the office sector and labora-tories.

EMC fans meet the requirements for in-creased RF shielding.

Particularly when using fan-and-filter units in conjunction with PC enclosures or moni-tor panels, DC variants are used which pro-vide effective protection from interference.

Rittal system climate control

Fan-and-filter units are ideal for dissipating heat loads cost-

effectively. The pre-requisite is that the ambient air must be

relatively clean and with a temperature below the desired

enclosure internal temperature.

The entire range of fan-and-filter units is now also available with

EMC shielding and all required rated voltages.

Not always full power!At lower ambient temperatures, the air throughput may be reduced. By adapting the fan-and-filter speed to match the temperature using a controller, noise generation is reduced.

Integral cooling technology offers everything

20 to 700 m3/h air throughput in a compact design The combination of heat load and enclosure size means that the correct fan-and-filter unit with the corresponding outlet filter is available. Every fan-and-filter unit in the broad Rittal range achieves its high air throughput with comparatively compact dimensions. This means that there is space for the mounting cutout for fan-and-filter unit and outlet filter in any enclosure, large or small.Now with protection category IP 54 as standard.

Fast assembly

Super-fast clip-on mountingThis guarantees fast, com-pletely secure attachment of the fan-and-filter unit. The pre-requisites for protection category IP 54 are met as standard. Screws are not required.

Removal of the louvred grille, likewise without any screws, means that filter mat changes can be achieved in next to no time.

Blowing or extracting?The air direction may be quickly reversed from blowing (standard setting) to extracting. Simply rotate the fan through 180°.

The styling of the vent louvres in Rittal fan-and-filter units guar-antees exemplary sta-bility of the air vol-umes in relation to pressure loss. The correct fan-and-filter unit has been chosen if the specified heat loss is dissipated whilst complying with the desired maxi-mum enclosure inter-nal temperature.

Benefits:● Air throughput from

20 to 700 m3/h

● Super-fast assembly

● IP 54 as standard

● Air flow direction may be reversed from blowing (standard setting) to extracting

● All fans also available with EMC shielding

Important● The prescribed heat loss

and the maximum antici-pated ambient tempera-ture define the required volumetric flow

● Always use the fan-and-filter units and outlet filters together

For calculation formulaesee page 189 or refer to the Internet atwww.rittal.de

Application diversity & design

In most cases, it makes sense to install the axial fan with the air directed from outside into the enclosure so that overpres-sure is created inside the enclosure. This is the deliv-ered state. This protects the inlet from unfiltered ambient air. By rotating the fan through 180°, the air flow may be reversed from blowing to extracting.

Aesthetics and functionTypical of the Rittal fan-and-fil-ter unit design is the extremely low build height. The super-slimline vent grille guarantees optimum air throughput with low noise generation. Com-bined with the technical fea-tures, Rittal fan-and-filter units meet all application require-ments.

Industrial useFilter mats and fine filter mats are available for segregating dust grain sizes of less than 10 µm.

Office use“As quiet as possible” is a cri-terion of the Workplace Ordi-nance and Rittal’s achieved development objective.

Network useSpecial designer fan-and-filter units in 48 V DC (20 to 230 m3/h) are used here.

Sealed and shielded

Also available with EMC shieldingAll fan-and-filter units and outlet filters are alternatively available with EMC shielding. The required conductive connection is achieved via a metallic coating on the fan-and-filter unit housing and a special sealing frame.

Protection functionsThe membranes of the fan grille in the form of a rain canopy provide exceptional protection against the ingress of splashed water and dust. The protection category IP 54 is achieved as standard.

Hosed water protectionParticularly for applications in the food industry, the hose-proof hood prevents the ingress of damp. The protec-tion category IP 55 is achieved in conjunction with fine filter mats.

Technical specifications:● The base parts of our fan-and-filter units

are given a metallic coating in a galva-nising process.

● All-round conductive connection between the fan housing and the mount-ing surface is achieved via a special EMC seal.

● All-round contact on the enclosure with a special EMC seal.

● Minimal number of additional attachment holes, thanks to the contact spring solu-tion.

● Square mounting cutout.● Super-slimline grille design.● The air direction (extracting or blowing)

is selected by simply rotating the fan.● Speed control possible (see accesso-

ries).● The plastic housing is temperature-

resistant from –35°C to +70°C and is also self-extinguishing to UL 94-V0.

Colour:RAL 7032. To order fan-and-filter units and outlet filters in RAL 7035, please change the final digit of the order number to a 7.

Supply includes:Complete fan-and-filter units ready to install, including drilling template, filter mat and assembly parts.
