Key Product Information


The all-welded PSD is constructed from low carbon, hot rolled structural steel. The door frame consists of structural tube steel machined for flatness, treated with a pure tin coating, and welded in place to provide the structural base for the pocket assembly. The door leaf features two thermal-bonded, tin-coated shielding skins which are mechanically attached to a leaf frame of aluminum or steel.

Bolt-on inspection/service panels, for door removal and pneumatic system access, are installed on the door pocket in areas that facilitate easy access for adjustments and/or repairs.

During pneumatic operation, rubber composite bladders inside the door frame are inflated, and the compression of the thermal-bonded, tin-coated surfaces creates a tight seal. For smooth and responsive operation, an inspection cover plate for the overhead carriage track utilizes a pneumatic cable cylinder. Oversized doors are available to accommodate vehicles, aircraft, and large industrial equipment and are available in a full range of custom sizes.


The PSD provides ultra-high performance attenuation levels when tested in accordance with MIL-STD-285?IEEE-299 and exceeds the performance of NSA 94-106, NSA 65-6, and CID/09/12A. The PSD can be configured to maintain 120 dB attenuation over frequency ranges from 1 KHz to 18 GHz.


Semi-automatic operation is appropriate for low to medium traffic areas. The semi-automatic door is opened and closed manually with inset handles conveniently located on the interior and exterior skins, to help facilitate the opening and closing operation. The RF sealing process is operated by a control valve or button mounted on a control panel, on both sides of the door. A fail-safe limit valve in the door pocket prevents the door from being inflated unless it is fully closed.
