Filter Fans

Forced ventilation fans maintain the correct temperature inside the cabinet by exchanging heated inside air for cool outside air.

MAIN ADVANTAGES:

Mount without screws into square openings using elastic clips
Replace the filter membrane from the outside without tools
Reversible airflow direction
Airflow up to 800 m³/h
Installation for plate thickness between 1,5 mm and 2,5
IP 54 standard rating
Wall and top mounting options
Operational temperature range from -10 °C to +70 °C
Permanent sealing gasket in polyurethane foam
UV protection

Airflow direction	Reversible
Sizing	When we use fan filters, we must have a target temperature inside the cabinet that is greater than the ambient temperature outside the cabinet (Te), which makes the difference (ΔT) between the inside and outside temperatures always positive. We can calculate the fan filtered airflow by taking the ratio between the thermal power (Q ) and the temperature difference (ΔT) and multiply that by the heat transfer coefficient (f ), which considers the physical properties of air, including heat and density which can change with altitude (m).
Fixing system	By elastic clips, otherwise by four self-threading screws
Supply includes	Unit with filter mat ready for connection
Recommendations for installation	The filter fan unit should be placed in the lower part of the enclosure to allow the cool air to enter into the enclosure and form a slight overpressure. This means that air flows into the enclosure through the filter fan unit without any dirt/dust and removes warm air from the enclosure through the outlet filter grid. If the filter fan unit is installed in the opposite direction, dust and dirt can enter into the enclosure along with cool air. The filter fan unit should be placed in the bottom third of the cabinet and the outlet filter grid should be placed as high as possible. This will prevent the accumulation of warm air in the upper part of the enclosure.
