The AirTAC GC30010AC2WGK AirTAC F.R.L. Combination Unit, 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 PT3/8" ports, a 5 µm element, a automatic 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 prepared air supply. This GC30010AC2WGK is the 300 size with a 3/8 in port in G (BSPP) thread. The filter element is the fine 5 um grade (the W option) and the bowl drains automatically, so collected water is expelled without manual attention. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, fitted with an external round gauge scaled in psi, and a reverse/check valve is fitted to hold downstream pressure if the supply drops. Mounting bracket included. Bowls on the 300 size are polycarbonate (PC).
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with port options in PT (standard), G and NPT, drain choices of differential-pressure, automatic or manual, filter grades of 40 um standard or 5 um, gauge scale options, and an optional reverse/check valve. Published flow data appears as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 clean, regulated and lubricated air to the tool-changer and clamping cylinders on a CNC machining centre, with the 5 um element protecting fine control valves from particulate carryover.
Prepares the air feeding stopper, pusher and diverting cylinders along a carton packaging conveyor, with automatic drainage coping with condensate that collects over continuous shifts.
Serves a drop point supplying impact wrenches and air ratchets at an assembly-plant workstation, where the lubricator carries oil mist to the tools and the regulator holds a steady set pressure.
Start with the port step: the 300 size carries 3/8 in ports; step up to 400 or 600, or down to 200, as your line's flow demand dictates - we will check the published flow curves against your consumption before you order. Choose the drain: automatic (as coded here) suits unattended duty, manual suits supervised points, and differential-pressure is the default where a pressure drop can trigger the drain. Filter grade is 40 um standard; the W code gives this finer 5 um element for sensitive downstream equipment. Gauge scale is selectable (MPa, psi or bar) and the round external gauge is optional against the embedded square type. Thread is PT as standard, with G and NPT as order options - this unit is coded G. A reverse/check valve (K) is available where holding downstream pressure matters, and a mounting bracket can be included or omitted.
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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Send us your line's air consumption and operating pressure and we will confirm the datasheet flow figures for this 300-size, 3/8 in unit on request before you order.
The A code means the filter bowl drains itself once collected condensate reaches a set level, with no manual intervention - useful for unattended or hard-to-reach installations. The alternatives are manual draining (code M) and the differential-pressure default; all three are order choices on the GC series, and this unit is supplied with the automatic drain.
