The Apex Instruments Heated Stainless Filter Assembly (SFA-82H) is for sampling particulates from space-limited industrial sources. The filter assembly has a two piece threaded clamping ring with an integral 300 watt ring heater . A Viton® O-Ring seals the 82.6 mm filter and prevents sample bypass. It has stainless steel inlet, outlet and a PTFE filter support screen (GA-3T). The inlet plate comes with a 5/8" tube union for swaging directly to a plain probe liner. The outlet plate has 3/8" female NPT connection and a male 3/8" full flow quick connect. The mating female quick connects with the thermocouple, which is supplied with the Unheated Sample Line (USL--QST) or SFA-82-QCF6, may be ordered separately. There is a thermal insulated blanket supplied with each unit. An unheated version is also available without the integral heater and blanket.
