High Pressure Filters

High Pressure Filters

High Pressure Filters

Application — In every S.I.C. coded industry requiring high pressure air/gas high efficiency purification to 10,000 psi operating pressure.

Housings — Constructed of carbon steel or stainless steel rated to 10,0000 psi operating pressure.

  • Single element housing from 1/4″ to 3″ NPTF, all inlet/discharge,. as well as flanged connections.

Elements — Double O-ring plug-in type bayonette connection. Self-locking type of stainless steel, nickel 200, nickel 400 layered stainless steel 5-ply construction. Pleated as well as Microdyne’s full-range of high efficiency, modular interchangeable range of elements.

The Unique Problem of High Pressure Applications

Compressed air and gases at pressures higher than normal pressures (above 100 to 125 psi) pose a more serious environmental threat because the contaminant concentration is many times higher than in a normal system.

Example: The existing contaminant at 100 psi (7 Bar) is increased 8 times that of atmospheric pressure.

At 4500 psi (300 Bar) the contaminant is increased 301 times that of atmospheric pressure.

High Pressure Applications with Low Pressure Efficiencies

Microdyne’s modular range of high efficiency filters is available in carbon steel or stainless steel housings capable of accepting the full range of interchangeable filter elements, including those available in our offering of coalescing, sterile, steam, prefilters, and activated carbon series with pressures to 6000 psi. Additional higher pressure filter housings are available to 10,000 psi operating pressure.

With the modular construction of the low pressure housing filter elements and the accommodating features of the high pressure housings, utilization of the same high quality elements of the low pressure series for the high pressure series is made possible. By using the same elements, availability of the elements is insured and performance is identical to the standard pressure ratings.

Standard inlet connections are from 1/4″ to 2″ NPT. Optional graylock connections or flanged connections are available on a custom designed basis to meet the specialized needs of our customers.

High pressure filters are available for air as well as most gases, including those with corrosive characteristics.

Elements for High Pressure Filters

Elements have a double O-ring, plug-in, bayonet-type connection with tie-rod. Microdyne’s full-range of high efficiency, modular interchangeable range of elements are all available for use.

  • SF-Sterile Filter — Removes bacteria and viruses in food, beverage, pharmaceuticals, and laboratory settings. Provides 100% sterile, bacteria-free compressed air at .01 micron.
  • PF-Prefilter — Provides maximum prefiltration of larger particulates. Rated at 100% efficiency @ 1 micron with minimal differential pressures. Extends the service life of the higher grade microfilter installed thereafter.
  • CFA-Coalescing Filter/Alpha Series® — The most effective coalescing filter in this series. Removes oil, water, and dirt from compressed air systems. Capable of removing contaminates down to .01 micron with 99.99998% efficiency. The special foam socks on the coalescers are resistant to mineral, synthetic, and decomposed oils.
  • CFB-Coalescing Filter/Beta Series® — Effectively retains oil, water, and dirt from compressed air. Designed to trap particulates .01 micron and larger at an efficiency of 99.9999%.
  • CFC-Coalescing Filter/Gamma Series® — Removes of oil, water, and dirt from compressed air systems. Performs with 99.99% efficiency at the .01 microns. To achieve economical operation in severely contaminated environments, it is best to install these filters upstream of the CFA filters.
  • ACF-Activated Carbon Filter — Eliminates odors from compressed air. Produces compressed air that is 400,000 times more pure than ambient air.
  • DF-Dustfilter — Removes rust and dust particulates from compressed air systems.
