The AirTAC GC40010LF2WK AirTAC F.R.L. Combination PT3/8 is a genuine G-series three-unit F.R.L. combination: a separate filter, a separate regulator and a separate lubricator assembled as one air-preparation station. It has PT3/8" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40010LF2WK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set for compressed-air lines. This 400-size unit is fitted with a PT3/8 (3/8 in) PT-threaded port, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain on the filter bowl, a low-pressure-type regulator with an embedded square gauge scaled in psi, and a reverse/check valve. The polycarbonate bowls give a clear view of condensate and oil level, and the mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and in PT, G (BSPP) and NPT threads, with manual, automatic or differential-pressure drains, 40 um or 5 um filtration, and MPa, psi or bar gauge scales. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application.

Specifications follow the official AirTAC G-series air-preparation data. The regulating band is set by the drain type: automatic and differential-pressure drains regulate 0.15 - 0.9 MPa, a manual drain regulates 0.05 - 0.9 MPa. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. The combination has no separate bracket code — the three units couple together with their own mounting hardware. Flow curves, weight and outline dimensions are not published in our data set — ask us and we will confirm from the factory datasheet.

Field order is size, port, drain, type, gauge, shape, scale, grade, thread, reflux — there is no bracket position on a combination. Constituent units, orderable separately as spares: GF400-10 filter, GR400-10 regulator and GL400-10 lubricator.
A GC is three separate units, so the filter and the regulator can each be serviced or replaced on their own. A GFC is the two-unit set, where filtering and regulating share one body — shorter, but the two functions come as one part. Both filter, regulate and lubricate.

Installed at a branch take-off on a factory compressed-air ring main, the unit filters water and particulate to 5 um, holds a stable low working pressure for the drop, and feeds oil mist to the tools and cylinders served from that drop.
Mounted on the air preparation panel of a packaging or conveyor line, the combination protects downstream valves and actuators from condensate and grit, regulates the supply to the line's set pressure, and lubricates the cylinders that drive diverters and pushers.
Fitted ahead of the pneumatic circuit of a machine tool or assembly station, the set delivers clean, regulated, lubricated air to clamps, tool-change cylinders and air bearings-style actuators, with the psi gauge giving the operator a local pressure readout.
Start with the port step: this unit is 400 size with a PT3/8 port, and the GC family steps through 200/300/400/600 with ports from 1/8 in to 1 in, so match the size to the line and the flow your circuit needs. The 5 um element (code W) suits downstream equipment that needs finer particulate removal than the 40 um standard element. Drain type is a real choice across the family: differential-pressure (fitted here), automatic, or manual. The regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us. Gauge scale is selectable (MPa, psi or bar) and an external round gauge is optional; PT is the standard thread with G (BSPP) and NPT available to order, and a bracket is included.
Flow for this family is published as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm sizing against the datasheet before you order.
Quick checklist
The PC bowls must not be cleaned with solvents — wipe them with a dry cloth. The lubricator adds an oil mist downstream of the regulator. If any branch of the line must stay oil-free, take that branch off before the lubricator, or use a GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line size and the flow your application needs, and we will confirm sizing against the datasheet on request before you order.
The L in the code marks the low-pressure regulator type; its exact adjustment range is not published in the catalogue data we hold, so confirm the range with us if your set pressure is critical. The filter bowl uses the differential-pressure drain (the default): it discharges collected condensate as the pressure differential across the element builds, with automatic (code A) and manual (code M) drains available in the family.
