Filter Fan
FF 018 | 21m³/h to 102m³/h

  • Very low noise
  • Minimal depth in enclosure
  • Functional design
  • Time-saving installation
  • UV resistant

Filter fans are used to provide an optimum climate in enclosures. The interior temperature of an enclosure can be reduced by channelling cooler filtered outside air into the enclosure thus expelling heated internal air. The resulting air flow prevents formation of localised hot pockets and protects the electronic components from overheating. These filter fans are intended for indoor use. The plastic used for the hood is highly UV light resistant.

Special features

  • The self-adhesive seal of the mounting frame prevents dust and water from entering the cabinet.
  • Functional design of the intake and exit fan hoods very effectively prevents direct intrusion of falling water and dust. The advantage is that the filter mat does not get so quickly contaminated with dirt and thus does not need to be exchanged so often.
  • The air channeling makes the filter fan particularly quiet in operation.
  • Functional and modern design enables time-saving assembly and maintenance.
  • The direction of air flow can easily be switched by reversing the axial fan (sizes 1 to 3).
  • EMC versions and other voltages on request.

Time-saving assembly and maintenance

STEGO´s filter fans are easily installed by one person from outside the cabinet.

1.) Make cut-out in the cabinet wall. The cut edge of the cabinet opening should be free of dirt, filings and grease. A template for the enclosure cut-out is included in the delivery of the filter fan.
2.) Remove protective film from the sealing strips on the mounting frame. Press mounting frame into the cabinet opening. The frame stays permanently in the cabinet. (For size 176mm and up we recommend additional screw fixing.)
3.) Electrically connect the axial fan using the clip connectors. Push the unit into the mounting frame. Fix using screws.
4.) Insert the filter mat in the hood. Clip on. Finished.

Changing the filter mat or fan is quickly done by one person. To change the filter mat simply remove the filter hood, insert the new mat and snap the hood back again. No tools required. Maintenance of the fan can easily be done without removing the mounting frame (2).
