The AirTAC GC400C10F2G AirTAC F.R.L. Combination, G3/8 (3/8 in) 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 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 compressed-air treatment set. This GC400C10F2G is the size 400 unit with a G3/8 (3/8 in) G-thread port. It removes water and particulate down to the standard 40 um grade, regulates downstream pressure within the 0.15-0.9 MPa (20-130 psi) standard adjustment range, and adds oil-mist lubrication for downstream air tools and actuators. The filter bowl uses a differential-pressure drain, the regulator is the standard type and carries an embedded square gauge with a psi scale, and no reverse/check valve is fitted. A mounting bracket is included.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600, with a choice of port sizes, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um (W) filter grades, gauge scale options and reverse/check valve variants. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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-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 impact wrenches, nut runners and pneumatic presses at assembly stations, where one set filters supply air, holds a set working pressure and mists oil to the tools.
Supplying case packers, labellers and carton-closing cylinders on a packaging conveyor, keeping moisture and pipe scale out of the valves while lubricating the actuator air.
Treating the shop-air feed to machining centres and pneumatic clamping fixtures, protecting spindles' air seals and regulators from condensate and delivering oiled air to clamps.
Start with the size and port step: 200, 300, 400 and 600 cover progressively larger ports and higher air demand, so match the size to the flow your line actually draws rather than to the pipe alone. Then set the drain: differential-pressure (as fitted here) discharges collected condensate automatically on pressure differential, while automatic and manual drains are orderable variants. Choose the filter grade: 40 um is the standard element and 5 um (code W) suits applications needing finer particulate removal. Pick the gauge scale (MPa, psi or bar) and thread (PT standard; G and NPT as order options); a bracket is included. Because flow is published as curves and not as a single rating, 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, not as a single rated figure, so no single flow number can be quoted here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The trailing G in the code specifies a G (BSPP) parallel thread on the G3/8 (3/8 in) port. PT is the standard thread for the series, and G and NPT are catalogue options you select when ordering, so match the thread to your existing fittings.
