The AirTAC GC400C15ALC2WK AirTAC F.R.L. Combination 1/2 in PT 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 air filter, pressure regulator and oil-mist lubricator assembled into one supply unit. This GC400C15ALC2WK is built in size 400 for a 1/2 in PT port. The filter stage carries the 5 um element (code W) for finer water and particulate removal than the standard 40 um grade, with an automatic drain (code A) that discharges collected condensate without manual attention. The regulator is the low-pressure type, and the set is fitted with an external round gauge reading in psi (code C2), a reverse/check valve (code K) and a mounting bracket. The filter and lubricator bowls are PC (polycarbonate) at size 400. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and is configurable by drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um optional), gauge style and scale (MPa, psi or bar), reverse/check valve, and G or NPT thread options. Flow is published as curves rather than a single rated figure, 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.

Feeds filtered, regulated and lubricated air to clamps, tool-change cylinders and spindle ancillaries on a machining centre, with the 5 um element protecting tight-tolerance valves.
Supplies the pneumatic cylinders that index and stop bottles on a filling line; the lubricator maintains a steady oil mist to the actuators through long production runs.
Conditions the air at each workstation drop in a paint shop, where the 5 um grade and automatic drain help keep water and particulate away from spray equipment while the low-pressure regulator holds the set pressure.
Choose the size and port step against the air demand of the downstream circuit: size 400 with a 1/2 in PT port sits in the middle of the GC range, which runs from 1/8 in (size 200) up to 1 in (size 600). Pick the drain to suit access: this unit has an automatic drain, while differential-pressure (default) and manual versions are available. This configuration carries the 5 um filter element instead of the standard 40 um grade - select W when downstream equipment needs finer filtration. The gauge here is an external round type reading psi; embedded square gauges and MPa or bar scales are the alternatives. Thread is PT as standard, with G (BSPP) and NPT as order options. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. Note this is the low-pressure regulator type; confirm the adjust range with us if your set pressure is below the standard band.
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 there is no one number we can quote. Send us your air demand and line conditions and we will confirm the flow and datasheet figures for this size 400, 1/2 in unit on request.
The code carries the L type, so the regulator is the low-pressure version rather than the standard one; its exact adjust range is not published in the material we hold, so confirm your set pressure with us before ordering. The rest of the decode is standard GC: 5 um filter element, automatic drain, round psi gauge, reverse/check valve and included mounting bracket.
