The SPSD-Positive Seal Dampers by Swartwout provides filter wall isolation for varying filter media, including HEPA systems.  Additional applications include isolation of bio-hazardous materials in laboratories.  Examples include post offices, hospitals isolation suites, pharmaceutical, food processing, military facilities, disease laboratories, biotech, campuses, etc.

The standard SPSD-Positive Seal Dampers by Swartwout is offered in galvanized and coated steel, with available stainless steel or aluminum for more demanding applications, such as contaminants in the air stream, or specific materials of construction. 

The “Low” or “Zero” leakage design is a cost-efficient alternative to other damper types for certain applications.
