Fil-Trek
Industrial filtration cartridges, bags, housings, strainers, and turn-key pump/filter skids — FRP corrosive-service vessels, ASME code-stamped housings to Class 2500.
What LibertyCES specifies from Fil-Trek
Pleated PTFE membrane for aggressive liquids, NSF-61 compliant high-flow elements to 500 GPM, and stainless wire-mesh for polymer-media limitations.
FRP fiberglass housings for corrosive/marine service, and duplex dual-vessel designs enabling zero-downtime bag swaps.
Up to ANSI Class 2500 in carbon steel through Hastelloy/Inconel/titanium, plus a self-cleaning automatic strainer named for -50°F methanol service.
Frequently Asked Questions
What is a duplex bag filter housing used for?
Duplex (dual-vessel) housings like Fil-Trek's DSL/DTL/SLDV/TLDV Series use a valve changeover to enable zero-downtime bag swaps — a real engineering feature for continuous chemical dosing or process lines that can't tolerate a filtration shutdown.
What materials are available for Fil-Trek fabricated strainers?
Carbon steel, 304/316 stainless steel, duplex, super duplex, Hastelloy, Inconel, and titanium, rated up to ANSI Class 2500 — one of the broadest exotic-alloy ranges available for a strainer in the LibertyCES catalog.
What is FRP housing material and when is it used?
Fiberglass-reinforced plastic (FRP) is a non-metallic pressure vessel material explicitly built for corrosive and marine service — a real, distinct material class from metal alloys or PVC/PP/PVDF fittings, available on both cartridge and multi-bag housings.
