The TSI AeroTrak® High Pressure Diffuser (HPD) Model 7960 is a specialized accessory designed to reduce high-pressure gas to near-atmospheric levels, enabling accurate measurement of particulate contamination in compressed gas systems. It’s specifically tailored for integration with TSI AeroTrak portable particle counters, making it ideal for cleanroom and contamination-sensitive environments.
Key Features:
- Reduces pressure up to 120 psi (8.27 bar) to near-atmospheric conditions.
- Isokinetic-like sampling for representative particle capture.
- 1.0 cfm (28.3 L/min) nominal flow rate.
- Designed for Clean Dry Air (CDA), Nitrogen (Nâ‚‚), and Argon (Ar) sampling.
- No manual calibration or adjustments required.
- Exhaust HEPA filter (>99.97% for 0.3 µm) prevents contamination when disconnected.
- Passivated stainless steel enclosure resistant to cleanroom chemicals.
- Compatible with TSI portable particle counters.
Key Applications
- Pharmaceutical manufacturing
- Electronics assembly
- Cleanroom and clean manufacturing
- Compressed gas quality validation to ISO 14644-1, ISO 8573-1, and SEMI F49.8 standards
