Airtight/Gastight Doors

Exclusive Sonicbar® sealing devices, precision hardware and door control systems solve environmental containment

  2. Or control fumes, contamination, air pollution and dirt infiltration under ambient or low pressure differential conditions.

Door performance varies with opening size, frame and seal design, door swing and hardware requirements. Leak tested under ASTM Standard E283-73T. Our design staff can advise you as to model specifications to meet your specific needs.

Watertight Doors
Sonicbar® watertight doors are engineered and fabricated to meet your specific requirements no matter how large the opening. Their construction assures rugged, reliable, and low maintenance service life.

These protective doors are available in bulkhead, hinged panel and vertical/horizontal sliding types to provide protection from flooding at the lowest possible cost.
