Pneumatic Sliding Door (PSD) System

Pneumatic Sliding Door for High-Security Shielding

Pneumatic sliding door (PSD) systems provide exceptional RF attenuation and controlled access for facilities requiring top-tier electromagnetic shielding. Built on a welded steel frame with tin-coated surfaces, the door forms a reliable metal-to-metal RF seal without relying on gaskets or contact fingers. The pneumatic logic allows semi-automatic or fully automatic operation, making it ideal for high-traffic or restricted-space environments where swing doors are not practical.

Key benefits include:

• Exceeds MIL-STD-285, NSA 65-5, NSA 94-106, and CID/09/12A
• Maintains 120+ dB attenuation across 400 Hz–40 GHz
• Operates on clean, oil-free shop air at 80–120 psi
• Flush threshold design supports easy equipment movement

With versatile controls, oversized door options, and integrated safety systems, the PSD provides a reliable, customizable solution for secure RF-shielded enclosures and critical-access facilities.
