TEM Filter Company

TEM Filters

TEM filters were first produced in 1973. The first filters used an unbindered glass fiber media before PTFE membranes became available. This product was extremely successful with all process gases.


In 1986 Ewald Associates purchased the TEM product line and set out to maximize the designs. Having improved the housing design, interior finish, introduced electropolishing, and eliminated fiber migration, we set out for new products. PTFE membrane based products were introduced shortly there after. The emphasis for the TEM design was proper support of the PTFE media and economy of housing design.


Our efforts in stainless steel and nickel medias were focused on sintered fiber designs. The superior flow characteristics of sintered fiber over sintered powder made the choice obvious. The flow rates of these metal medias are actually better than the PTFE membrane based products.
