High Pressure Gas Diffusers

High Pressure Diffuser: HPD™

The HPD™ High Pressure Diffuser reduces the pressure of gases for particle counters operating at atmospheric pressures. Compatible with non-toxic, non-flammable gases such as Clean Dry Air (CDA), Argon, Nitrogen and Carbon dioxide. Aerosol Monitoring Accessory: use with the Lasair, IsoAir Pro NanoAir, or Airnet II particle counters to check contamination in pressurized gas.

Enable Accurate Particle Counting in Compressed Gas

HPDs reduce high-pressure gas (up to 150 psi) to near atmospheric pressure, allowing particle counters to function correctly without damaging sensitive flow-metering systems.

Versatility Across Gases and Applications

Compatible with non-toxic, inert gases like Clean Dry Air (CDA), nitrogen, argon, and CO₂, making HPDs suitable for semiconductor, pharmaceutical, and clean manufacturing environments.

Two models available to meet different ranges of particle sizes.

Economical Monitoring

Allows the use of standard atmospheric particle counters for pressurized gas monitoring, avoiding the need for dedicated high-pressure instruments—significantly reducing cost for occasional or trend monitoring
