High Pressure Diffuser

The HIGH PRESURE DIFFUSER was designed for use with Lighthouse Airborne Particle Counters in applications where the sample is under pressure. Standard applications include sampling of CDA, Nitrogen and other inert gasses.

Available in Vented or Ported versions, the configuration is determined by the excess sample gas being vented into the test area (Vented model) or exhausted outside of the test area (Ported model). The High Pressure Diffuser will accept inlet pressures ranging from 30 to 150 psi (2 to 10.3 bar) and is available with a 1.0 or 0.1 CFM outlet flow to meet your application needs.

The 5-piece stainless steel design is constructed with replaceable Fluorocarbon (Viton) O-Rings for easy disassembly and cleaning or service.
