Dolph microwave offers a standard line of waveguide pressure inlet from WR28 to WR650 for pressurizing Waveguide systems with clean air or other gasses. Waveguide pressure inlet are available in almost all combinations of flange type and have a 1/8" NPT female inlet. We can customize waveguide pressure inlets to your specifications upon request.
Flange type: Multiple types available - see Dolph Microwave Flanges page.
Finish: Corrosion protection plus black/grey top coat.

Waveguide pressure inlets are also called air inlets, which can be added to many waveguide assemblies composed by multiple individual devices.
These waveguide components in microwave engineering create the most compact and cost effective solutions.
