FA Wall Mounted Exhaust Fan with Damper
Compact square metal axial exhaust fans with automatic gravity shutter louvers and rear safety guards for commercial rooms, workshops, plant rooms, storage spaces, and utility ventilation in Saudi Arabia.
What is an FA wall mounted fan with damper?
An FA series wall mounted exhaust fan is a compact square metal axial ventilator equipped with automatic gravity louvers that open under exhaust airflow and drop shut when stopped. Sized using Room Volume (cu. ft) × Target ACH ÷ 60 for low static pressure wall openings (< 30 Pa), delivering 350 to 3,120 CFM.
Is an FA wall fan with damper suitable for your space?
Evaluate room volume, heat and odor sources, and external wall exposure before selecting from the FA20-B to FA50-B range.
