The AirTAC GC400C10AC2WK AirTAC F.R.L. Combination, PT3/8 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 assembled into one supply unit that conditions compressed air in a single installation. This GC400 configuration is built for PT3/8 ports and carries the 5 um filter element (code W) with an automatic drain, so condensate is expelled from the polycarbonate bowl without manual intervention. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), a round psi gauge is fitted, a reverse/check valve holds the downstream setting, and the mounting bracket is included. Operating temperature is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 inch, plus choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale (MPa, psi or bar), thread (PT standard, with G and NPT as order options) and a reverse/check valve. Flow is published as curves rather than a single rating, 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.

Feeds impact wrenches, air cylinders and clamps at assembly stations: the 5 um element strips water and particulate, the regulator sets tool pressure, and the lubricator mists oil to keep air tools running.
Supplies the cylinders and grippers that index bottles along a filling conveyor. The automatic drain clears condensate during continuous runs and the check valve holds the regulator setting through pressure dips.
Conditions air for pneumatic workholding and tool-change circuits on a machining centre: fine 5 um filtration protects precision valves, the regulator holds clamp force, and the psi gauge gives operators a direct read.
Step through the GC sizes (200/300/400/600) to match the port and the flow your circuit needs; this unit lands on PT3/8. The 5 um element (code W) on this model gives finer filtration than the 40 um standard - useful ahead of precision valves - while the automatic drain suits unattended duty; manual-drain and differential-pressure-drain variants are available if you prefer. The round psi gauge is fitted here; the embedded square gauge is standard and scales can be specified in MPa, psi or bar. Thread is PT as standard, with G (BSPP) and NPT as order options, and the bracket is included. Flow is published as curves, not a single rating - send us your air demand and we will confirm sizing from the datasheet 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 curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your air demand and operating pressure and we will confirm the sizing from the datasheet on request before you order.
This model carries the W-code 5 um element, which filters more finely than the 40 um standard and is the better choice ahead of precision valves, instruments and sensitive actuators. Both grades are available across the GC sizes, so you can match the element to each circuit.
