Pressurizing Sections
PENN ENGINEERING's Pressure Sections are used where air or other gases are to be introduced into the waveguide system. Stainless Steel Schrader valves ("tire valves") are used as inlets for air/gasses. Pressure Gauges are supplied in either 0-15 psi or 0-30 PSI ranges to monitor internal pressure. Units are 1.06 max. VSWR typ..

Brass units are Silver Plated per QQ-S-365D Class A, Aluminum units are Chem-filmed per MIL-C-5541E, and both are finished with PENN ENGINEERING's Metallic Blue Paint.

We will build custom Pressurizing Sections to your specifications.
