HEPA Filter 33058B

33058B HEPA Filter is a compact, 25mm DIA filter commonly used to compliment Fluidic’s range of low differential pressure transmitters.  33058B HEPA filter has been designed to
meet the stringent requirements of the nuclear, pharmaceutical and biotech industries.  It is a stocked accessory, commonly used with our Micatrone MF-PFA transmitter assemblies to minimise risk of airborne particulate contaminating the inner mechanisms of the transmitter.  33058B provides a quantified level of protection to pressure monitoring equipment fitted to potentially hazardous ventilation and process systems within these facilities.
