Overview
The Membrane Structure Fan is a complete outdoor-rated fan unit engineered specifically for air-supported membrane buildings such as air domes, coal sheds, and temporary warehouses. Built around our proven PAS/PNS standard plug fan, this unit features an integrated weatherproof enclosure designed to withstand continuous outdoor operation.
This fan solution provides the high-pressure, continuous-duty performance required to maintain air pressure in membrane structures while offering superior weather resistance and low maintenance operation in outdoor conditions.
