Series 39 and 98 membrane filters
The series 39 and 98 membrane filters consist of a housing with a porous PTFE membrane filter, which is supported by a sintered porous disk located on the “outlet” side of the housing. Gas enters through the “inlet” port on the upstream side of the membrane and exits from the “outlet” port on the downstream side. Entrained liquid will not flow through the membrane and will exit through the “by-pass” port on the upstream side of the membrane, completely protecting sensitive instrumentation from moisture.
For the membrane to operate correctly there must be by-pass flow.
