Selection & support
Match airflow, supply voltage and installation space before confirming a filter fan model.
Filter fans suit cabinets that can exchange air with a cooler ambient environment and need a practical airflow path through a filtered inlet and outlet. Confirm IP rating, mounting cut-out and the planned filter maintenance interval for the installation.
Read cooling guideUse the airflow calculator to estimate required airflow, then compare catalog data for supply voltage, airflow, dimensions and accessories. Include ambient conditions and heat load in any inquiry so the team can review the shortlist.
