The AirTAC GC400C15ALF2WGK AirTAC F.R.L. Combination, G1/2 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-piece F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator supplied as a matched air-preparation set. This GC400C15ALF2WGK is built in size 400 with G1/2 (BSPP) ports, 5 um filtration (the W grade, finer than the 40 um standard), an automatic drain on the filter bowl, a low-pressure regulator, an embedded square gauge scaled in psi, a reverse/check valve, and a metal bowl; the mounting bracket is included.
It is a genuine AirTAC part for compressed air, rated at up to 1.0 MPa (145 psi) maximum inlet pressure and -5 to 70 C (non-freezing) operation. The GC family spans sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades, gauge scales and threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and the datasheet 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.

Filter, regulate and lubricate the shop air feeding pneumatic clamps and tool-change cylinders on a CNC machining cell, with 5 um filtration helping protect tight-tolerance valve spools.
Condition the air feeding grip, capping and divert cylinders on a bottling or canning line, where the automatic drain handles condensate from a high-duty compressed-air supply.
Supply regulated, lubricated air to pusher and diverter cylinders along a packaging conveyor, keeping cylinder seal life consistent through continuous multi-shift running.
Size and port step up together across 200, 300, 400 and 600; this unit sits at size 400 on G1/2 ports, so pick the size whose published flow curve covers your demand. The 5 um W grade suits circuits that need finer particulate removal than the 40 um standard, and the automatic drain keeps the filter bowl clear without daily manual attention. The L code makes this the low-pressure regulator type; the exact regulation range for the low-pressure type is not published, so confirm it with us before ordering. The gauge here is the embedded square type scaled in psi (MPa and bar scales are alternatives), and the K code adds a reverse/check valve. Thread on this unit is G (BSPP); PT is the standard offering with G and NPT as orderable options, and a bracket is included. Because flow is published as curves, not 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. Send us your air demand and we will confirm the flow curve and datasheet for the GC400 at 1/2 in ports before you order.
L marks the low-pressure regulator type. The exact regulation range for the low-pressure type is not published in the catalogue, so confirm it with us when specifying; the unit's maximum inlet pressure remains 1.0 MPa (145 psi).
