Inflatable gasket doors are recommended when a watertight or airtight seal and a flush bottom sill are required. This type
of door is often used for inside locations such as labs and clean rooms. The doors are available with either single or dual inflatable gaskets, and can be used for pressures up to 40 psi.

The gasket(s) are inflated using a hand or foot pump, portable compressed air tank or compressor, bottled gas, or shop air. Power inflation/deflation, local and/or remote activation, interlocking, and monitoring are among available options.

For cost savings, we recommend only using dual gaskets for critical applications. Care should be taken to maintain the gasket-sealing surface so as not to damage the gasket.
