HPD™III High Pressure Diffuser

HPD™III High Pressure Diffuser

Compatible with non-toxic, non-flammable gases.

The HPD III High Pressure Diffuser is compatible with non-toxic, non-flammable gases such as Clean Dry Air (CDA), Argon, Nitrogen and Carbon dioxide.

Sampling gases at pressures greater than sea level, such as 25 – 100 psig, is challenging for particle counters. Connecting pressurized air or gas to a particle counter can defeat its flowmetering system and possibly damage the instrument.

High Pressure Diffusers (HPDs) have been developed to address particle counting in compressed gas. HPD’s reduce the pressure of the gas to about atmospheric pressure by allowing some of the air/gas to diffuse out of the system and allow the Lasair Pro or Lasair III particle counter’s flow-metering system to function as designed.
