Filter Fans

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

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

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.
