APPLIED PHYSICS is happy to offer a High Pressure Diffuser to assist in the testing of compressed air/gas systems for total air particulates. This diffuser can be used in conjunction with almost any Laser Particle Counter (LPC) on the market with a 1 CFM, or 28.3, 50, 75, or 100 LPM Flow Rates for testing of particles down to 0.3 microns. With the three piece construction of electro-polished 316SS, the unit itself generates virtually no particulate matter. It is ideal for accurate particulate monitoring of your Compressed Air and Gas Systems.
