In addition to the easy mounting axial fan, the self-adhesive seal of the mounting frame prevents dust and water from entering the cabinet. The functional design of the intake and exhaust fan hoods very effectively prevents direct infiltration of falling water and dust. The design also provides air channeling which makes the filter fan particularly quiet in operation.

This outdoor filter fan can be used in outdoor enclosures where warm air has to be dissipated on account of increased thermic development. To clean and exchange the filter mat, it is only necessary to open the lockable door of the outdoor hood. A protection type of NEMA 4 (IP55) is achieved due to the special design of the hood and the use of fine filter mats. The plastic casing is impact resistant, highly weather proof and resistant to UV light.
