Category: Compressed Air and Gas Filters
Product Code: Micro-Series-Air/Gas Microfiltration Products

Finite® Filter’s Micro-Series filters are designed to provide absolute rated membrane filtration for the semiconductor, pharmaceutical, and 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 lowest pressure drop at rated flow and the highest efficiency in the filtration industry. These important factors provide substantial savings for our customers.

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