The AirTAC GC40015AC2WGK 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment stack. This configuration, GC40015AC2WGK, is the size 400 unit with a G1/2 (1/2 in) G-thread port. The filter element is the fine 5 um grade (W) and the bowl drains automatically, so collected water is expelled without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round external gauge on the psi scale is fitted so the set pressure can be read directly. A reverse/check valve (K) is fitted and the mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter and lubricator bowls are polycarbonate (PC); only the size 600 units use aluminium alloy bowls.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of PT (standard), G or NPT thread, differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, and gauge scale options. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the datasheet figures for your application on request.

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: GF400-15 filter, GR400-15 regulator and GL400-15 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 guns and air-assisted applicators on a paint line, where the 5 um element, regulated pressure and consistent oil misting protect finish quality across a shift.
Supplying the pneumatic cylinders on a carton-forming and case-sealing conveyor, with regulated pressure for consistent stroke force and automatic drainage for continuous running.
Conditioning the air feeding clamping cylinders and air vices on machining centres, where the psi gauge lets the setter verify clamp pressure and the lubricator keeps actuation smooth.
Start with the port and size step: the GC400 carries a 1/2 in port, and the 200/300/400/600 ladder exists so you can step up when your circuit needs more flow capacity - match the step to the air demand of the downstream cylinders or tools rather than to the pipe alone. Decide the drain: automatic (as fitted here) suits unattended or hard-to-reach installations, manual suits supervised points, and differential-pressure is the default. Choose the filter grade: 40 um is the standard element for general plant air, while the 5 um (W) element fitted here suits finer downstream equipment. Pick the gauge scale (MPa, psi or bar) and the thread: PT is the standard, with G and NPT available as order options. A bracket is included with this unit.
One honest note on sizing: flow for this series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the correct size against the datasheet curves 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated number, so we do not state a figure here. Tell us your application and air demand and we will confirm the sizing against the datasheet curves on request before you order.
In the code GC40015AC2WGK, the W position selects the optional 5 um fine filtration instead of the 40 um standard element, and the A position selects the automatic drain instead of the differential-pressure default. That pairing suits fine downstream equipment and installations where nobody opens the drain by hand. Both choices can be ordered differently within the GC400 range if your application prefers the standard grade or a manual drain.
