The AirTAC AirTAC GC400C10LC2WG F.R.L. Combination, 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-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one coordinated set for compressed-air preparation. This GC400C10LC2WG is the size 400 unit with a G3/8 (BSPP) female port. The filter element is the fine 5 um grade (code W) and the bowls drain by differential pressure, so condensate is expelled automatically when the pressure differential across the element calls for it, with no manual draining routine. The regulator is the low-pressure (L) type, and the set carries a round pressure gauge with a psi scale; a mounting bracket is included and no reverse/check valve is fitted.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port sizes stepping up from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard or 5 um), gauge style and scale, thread form and reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet figures against 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.

A press cell running air cylinders on a low-pressure circuit gets filtered, regulated and lubricated air from one GC set at the cell drop, keeping the cylinders and valves supplied without three separate components to mount and plumb.
At an impact-wrench and ratchet station, the 5 um element removes water and fines that chew up tool vanes, the regulator holds a steady low-pressure setting, and the lubricator mists oil into the tool air line.
Packaging machines with air actuators and grippers need clean, stable, lubricated air at each drop; a GC400 set at the line feed conditions the supply before it reaches the machine's valve manifold.
Start with the port and size: this unit is size 400 with a G3/8 port; smaller GC300 and larger GC600 sets cover lighter and heavier circuits, so step size against the air demand of the line. Choose the filter grade to match downstream sensitivity - 40 um is the standard element, while the 5 um (W) element fitted here suits finer downstream equipment. Drain type is a real choice: differential-pressure (fitted here), fully automatic, or manual. On the regulator side, pick standard or low-pressure (L) type - this code is the low-pressure variant - and select gauge style and scale (square embedded or round external; MPa, psi or bar). Thread is PT as standard, with G (BSPP) and NPT available as order options; a bracket can be included or omitted.
One honest note on sizing: rated flow for this series is published only as performance curves, not as a single number, so we do not quote a flow figure here. Send us your application details and we will confirm the sizing and datasheet figures on request 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not quote a flow number here. Tell us your application - port size, downstream equipment and working pressure - and we will confirm the flow and datasheet figures on request before you order.
The L in GC400C10LC2WG marks the low-pressure type of regulator, intended for circuits that run below the pressures a standard GC regulator is set up for. The exact adjustment range for this low-pressure variant is not published in the material we hold, so ask us to confirm it on request. A standard-type GC400 is available if your circuit does not need the low-pressure variant.
