Enclosure Filter Fan Alternative
In dusty environments, control-cabinet cooling often uses filtered ventilation units. The Jiefeng cabinet filter fan series (including the DC cabinet filter fan line) is an alternative to imported enclosure ventilation filter units.

FAQ
How is a cabinet filter fan different from a plain axial fan?
A filter fan adds a filtration layer so intake air is filtered before entering the enclosure, suited to dusty control-cabinet environments.
What are Jiefeng enclosure filter fans used for?
Control cabinets, electrical enclosures and automation equipment where dust protection and ventilation cooling are both needed.
Why does a filtered fan need static-pressure consideration?
Filters add resistance, so installed airflow is lower than free-air delivery. Evaluate airflow at target static pressure.
What parameters are needed for cabinet cooling selection?
Enclosure size, total heat load, ambient temperature, allowable internal temperature, supply voltage, cutout size and ingress protection.
