Product Details

The TSI AeroTrak ® Model 7960 High Pressure Diffuser (HPD) accessory allows the TSI AeroTrak Particle Counters to measure particulate contamination in high-pressure compressed gas systems. As particle counters cannot sample high pressure gas, they require HPD accessories to reduce the pressure of compressed gases to assess the cleanliness level of compressed gas systems.

Features and Benefits 

  • Reduces gas pressure of up to 120 psi (8.27 bar) to near atmospheric pressure
  • For monitoring and testing to ISO 14644-1 and ISO 8573-1
  • Isokinetic-like sampling
  • Use with AeroTrak Portable Particle Counters for pharmaceutical and electronics assembly
  • Exhaust HEPA filter protects HPD accessory from contamination when disconnected from compressed gas source
  • No manual adjustments or calibration required
  • For use with Clean Dry Air (CDA), Nitrogen (N 2 ) and Argon (Ar)
  • Passivated stainless steel enclosure resists cleanroom chemicals
  • 1.0 cfm (28.3 lpm) nominal flow rate
