The AirTAC GC300C10AC2WGK 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 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 supply unit. This configuration, GC300C10AC2WGK, is the size 300 unit with G3/8 (BSPP) ports. It filters compressed air to 5 um (the finer of the two catalogue grades), regulates downstream pressure with the standard regulator over 0.15-0.9 MPa (20-130 psi), and adds oil-mist lubrication for downstream pneumatic components. The filter bowl drains automatically, an external round gauge reading in psi is fitted, a reverse (check) valve is included (code K), and the mounting bracket is supplied.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade, gauge type and scale, thread form (PT standard; G and NPT to order) and 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: GF300-C1 filter, GR300-C1 regulator and GL300-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 spray guns on a paint line: the 5 um element removes water and particulate, the regulator holds a steady gun pressure, and the lubricator is bypassed or set as the line requires for finish-critical work.
Supplying the pneumatic cylinders and air grippers that index, stop and divert bottles on a packaging conveyor, with filtered, regulated and lubricated air from a single G3/8 drop.
Running the pneumatic clamps, tool-change actuators and chip-ejection jets on a machining centre, where the check valve helps hold the downstream circuit and the psi gauge gives operators a local reading.
Size and port step up together: 200, 300, 400 and 600 cover ports from 1/8 to 1 inch, so pick the size whose flow curve covers your consumption at your working pressure - we can check the curve against your demand. Drain type is a real choice: automatic (this unit, code A) drains the bowl without attention, manual needs operator action, and differential-pressure drains only when the element loads up. Filter grade is 40 um standard or 5 um (code W, fitted here) where finer particulate removal is needed. Gauge options are the embedded square gauge or the external round gauge (fitted here) with MPa, psi or bar scales. Thread is PT as standard with G (BSPP, this unit) and NPT as order options; a bracket is included and a check valve can be specified (code K, fitted here).
Because flow is published as curves and not as a single rated figure, ask us to confirm sizing against your application 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a figure here. Send us your working pressure and air consumption and we will confirm the sizing from the datasheet curves before you order.
The code says so: W is the 5 um element (40 um is the standard grade) and A is the automatic drain, which empties the bowl without operator attention. If your application tolerates coarser filtration or you prefer manual control, the same size 300 unit is available in those variants - ask us for the alternative codes.
