SchwankAir 3500/4500 Series

High Efficiency Air Curtains

3500-4500 Series
The All-New SchwankAir 3500/4500 series easily mounts on any door up to 26’ 3” feet high in order to create an air seal to keep conditioned air in the building and keep dust, dirt, and insects out. Multiple units can be stacked together for larger door widths.

How SchwankAir Curtains Work

SchwankAir Curtains create an effective seal by re-circulating the facility air in a smooth laminar flow across an open doorway. This creates an air seal, like a waterfall, that prevents leakage of air between two areas with different pressure and climate. The more laminar this air flow, the harder it is for outside air, insects, or dust to penetrate the air curtain.
