The AirTAC GC400C10LF2WK 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one supply package. This GC400C10LF2WK is the size 400 unit with a 3/8 in PT port. It filters compressed air down to 5 um (the fine W element, against the 40 um standard), removes collected water through a differential-pressure drain, regulates pressure with the low-pressure type regulator, and meters oil mist to downstream equipment. A square psi gauge is fitted, a reverse/check valve is built in, and a mounting bracket is included. The filter bowl on this size is polycarbonate (PC). Maximum inlet pressure is 1.0 MPa (145 psi); operating temperature is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, and can be ordered with manual or automatic drains, a 40 um or 5 um element, MPa, psi or bar gauge scales, G (BSPP) or NPT threads, and with or without the reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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-C1 filter, GR400-C1 regulator and GL400-C1 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.

Feeding spray booths and air-powered paint guns on an automotive finishing line, where the 5 um element, pressure regulation and oil misting are set up once at the line drop and serve every gun downstream.
A filtered, regulated and lubricated supply point for pneumatic clamps, blow-off and air hand tools at a CNC machining cell, with the built-in reverse/check valve included in the circuit.
Supplying cylinders and air-driven diverters on a packaging conveyor, where one combination unit conditions the air for the whole section instead of fitting separate filter, regulator and lubricator pieces.
The real choices in this series are all decodable from the code. Step the size (200/300/400/600) and port (06 to 25) against the flow your line needs - larger sizes carry larger ports and more flow capacity, though the exact figure comes from the flow curves. Choose the drain: differential-pressure (this model), automatic (A) or manual (M). Choose the filter element: 40 um standard or 5 um (W), as fitted here. Choose the gauge scale - MPa, psi (this model) or bar - and the thread: PT is standard, with G (BSPP) and NPT as order options.
Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
W selects the 5 um filter element instead of the 40 um standard element. The rest of the code reads: size 400, PT3/8 port, differential-pressure drain, low-pressure type regulator, square psi gauge, and a fitted reverse/check valve.
