The AirTAC GC400C15C2WGK 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 GC400C15C2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is the size 400 unit with a G1/2 (BSPP) port, fitted with the 5 um filter element (code W) for finer water and particulate removal than the 40 um standard, a differential-pressure drain on the filter bowl, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). It carries a round pressure gauge reading in psi, a reverse/check valve (code K) to hold downstream pressure when the supply is lost, and a mounting bracket. The maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The filter bowl on this size 400 unit is polycarbonate (PC).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread form and reverse/check valve. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing for your application before ordering.

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 spray guns and air-assisted applicators on a paint line, where the 5 um element, regulated pressure and oil misting in one package keep finish quality consistent across a shift.
Supplies the flap-fold and tamping cylinders on a packaging conveyor, with the check valve holding the set pressure if the plant air dips mid-cycle.
Prepares the air feeding tool-change clamps and pneumatic chucks on a machining centre, giving one filtered, regulated and lubricated take-off point at the machine.
Start with the size and port: GC400 with a 1/2 in port suits lines whose air consumption sits in the upper mid-range of the G-series span, and the honest way to check is against the published flow curves - we will confirm sizing on request. This unit already carries the 5 um element (code W); the catalogue standard is 40 um, so choose 5 um where downstream valves and cylinders need finer protection. The drain here is differential-pressure, which bleeds collected water automatically as the pressure differential rises; automatic (A) and manual (M) drains are orderable alternatives. The gauge is round with a psi scale; square embedded gauges and MPa or bar scales are also available. Thread is G (BSPP) on this code - PT is the catalogue standard, with G and NPT as order options - and the bracket is included. No flow number is stated as a rating because the catalogue publishes flow only as curves; ask us to confirm the datasheet figure for 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, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and consumption and we will confirm the datasheet curve and check the sizing for your application before you order.
The W in the code GC400C15C2WGK selects the 5 um filter grade, which removes finer water and particulate than the 40 um standard element. It is the right choice when feeding precision valves, cylinders or applicators; if your line does not need fine filtration, a 40 um version of the same combination is available to order.
