The AirTAC GC400C10LC2WGK AirTAC 3-Piece F.R.L., G3/8 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, pressure regulator and oil-mist lubricator built into one set, so each function stays individually serviceable. This GC400C10LC2WGK is the 400 size with a G3/8 (BSPP) port. It carries the W-coded 5 um filter element (40 um is the catalogue standard alternative), a differential-pressure drain on the filter bowl, the L-coded low-pressure regulator, an external round gauge reading in psi, a fitted reverse (check) valve, and a mounting bracket. The filter bowl on this size is polycarbonate (PC). Maximum inlet pressure is 1.0 MPa (145 psi); working temperature 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 to 1 inch, and options for drain type, filter grade, gauge and scale, thread (PT standard; G and NPT to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure 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.

Feeding pneumatic clamps, tool changers and blow-off circuits on a machining centre: the 5 um element strips water and fine particulate before they reach sensitive valves, the low-pressure regulator holds the set pressure, and the lubricator mists oil to the actuated components.
Supplying air cylinders and actuators on a filling or cartoning line, where the filter and differential-pressure drain keep condensate out of the valves, the regulator holds a steady setting, and the lubricator extends the service life of cylinders and directional valves.
Assembly benches and service bays running impact wrenches, ratchets and air rammers: the lubricator delivers a continuous oil mist to the tools, while the filter and regulator keep the supply air clean and at a stable pressure at each drop.
Size and port step up together across 200, 300, 400 and 600, with ports from 1/8 to 1 inch - choose the size whose flow curve covers your demand, and ask us to check it against the datasheet. On this family you select the drain (differential-pressure as fitted here, automatic, or manual), the filter grade (40 um standard or 5 um with the W code, fitted here), the gauge (embedded square as standard, or an external round gauge scaled in MPa, psi or bar - this unit has the round psi gauge), the regulator type (standard or the L-coded low-pressure type used here), the thread (PT is the standard; G and NPT are catalogue options to order), and whether a bracket is included. The adjustment range for the low-pressure type is not published, so confirm it with us before ordering if your set pressure is critical.
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 operating pressure and air demand and we will confirm the sizing against the datasheet on request before you order.
The W code in this model selects the 5 um filter element; the catalogue standard for the GC filter section is 40 um. Choose 5 um where downstream valves, cylinders or instruments need finer protection from particulate and water, and 40 um for general plant air. Both grades are catalogue options on the same size.
