Inline Duct Fans

Inline duct fans connect directly into round or rectangular duct systems: metal, plastic, EC and ultra-silent constructions for fresh air, exhaust and local pressurisation. Final selection is confirmed at the duty point (airflow / static pressure / voltage / control mode) and by project verification.

Filters use nameplate maximum values (max airflow at zero static pressure, max static pressure at zero airflow). Check the actual operating point on the performance curve of each model.
