Micro-Series

Finite’s Air and Gas Microfiltration Products

Membrane Elements and Housing Assemblies For:

  • Semiconductor/Microelectronics
  • Medical/Pharmaceutical
  • Food and Beverage

Finite® Filter’s Micro-Series filters are designed to provide absolute rated membrane filtration for the pharmaceutical, semiconductor, and for the food and beverage markets. Our pleated membrane media offers absolute removal ratings for contaminants as small as 0.01 μm while providing lower differential pressures than competitive membrane products.

Finite®s pleated PTFE media has the the highest efficiency and lowest pressure drop at rated flow in the filtration industry. These important factors provide substantial savings to you, our customers.

All of the filter housings are constructed of 316L stainless steel and have a max. pressure rating of 150 PSIG/10 bar. Connection sizes range from 1” NPT – 6” flange.
