Schwank Grand18/Grand26 (3500/4500) highlights
High-efficiency air curtain
Schwank air 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 airflow, the harder it is for outside air, insects, or dust to penetrate the air curtain.
