EMTEK’s unique High Pressure Diffuser (HPD) for sampling of compressed Air/Gas Systems for Microbial Contaminants with our P100, or V100/RCG Microbial Air Samplers and/or Total Particulates via Laser Particle Counter. The new HPD is Electropolished 316SS & allows for HEPA filtration of the exhausted volume. The unit can be autoclaved, or chemically sanitized for Microbial Testing of critical systems. The filtered exhaust also greatly reduces the output decibel level of the HPD. The HPD can be configured for testing at 28.3-50, or 75-100 LPM sample rates.
