The AirTAC GC400C10AC2GK AirTAC 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 GC400C10AC2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This configuration is size 400 with G3/8 (BSPP) ports, a 40 um standard filter element, an automatic drain on the filter bowl, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and a round pressure gauge reading in psi. A reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, 40 um or 5 um (code W) filtration, gauge scale, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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 cleaned, regulated and lubricated air to the pneumatic clamps, tool-change cylinders and chip-ejection actuators on a CNC machining centre, with the 40 um element protecting valves from swarf-laden shop air.
Supplying treated air to carton-forming, sealing and case-packing machinery, where the automatic drain copes with condensate from long compressed-air runs and the lubricator keeps cylinder seals working shift after shift.
Conditioning air for diverter gates, stoppers and lift-and-locate cylinders along a conveyor system, with the regulator holding a steady setpoint so sorting actions stay consistent through the day.
Size 400 with 3/8 in ports suits lines where air demand sits above the 1/4 in step; step up or down a size if your flow requirement or existing pipework points elsewhere. The automatic drain on this unit handles condensate without manual attention - choose manual drain only if you prefer operator-controlled draining, or differential-pressure drain as the default alternative. The 40 um element is the standard grade; specify 5 um (code W) if downstream equipment needs finer particulate removal.
The fitted round gauge reads in psi; MPa or bar scales are available if your team works in those units. Thread here is G (BSPP); PT is the catalogue standard and NPT is also an order option - match the thread to your fittings. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your air consumption 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 this series as curves rather than a single rated figure, so we do not quote a rated l/min or SCFM number. Tell us your application and required air consumption and we will confirm the flow and datasheet figures for the GC400 at 3/8 in before you order.
The A in the code GC400C10AC2GK selects the automatic drain, which expels condensate from the filter bowl without operator attention; manual and differential-pressure drains are the other catalogue choices. The C2 selects a round gauge with a psi scale - MPa and bar scales are also available, and an embedded square gauge is the standard alternative.
