The AirTAC GC300C10AF2WK 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 GC300C10AF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filtered-air supply station. This 300-size unit carries PT3/8 ports, a 5 um filter element (code W, finer than the 40 um standard), an automatic drain on the filter bowl, and a fitted reverse/check valve. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and an embedded square gauge scaled in psi; an external round gauge is optional. The filter bowl on this 300 size is PC (polycarbonate), and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8" to 1", drain choices (differential-pressure, automatic or manual), filter grades of 40 um standard or 5 um optional, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to 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-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.

Feeds clean, regulated and lubricated air to the tool-clamp, pallet-clamp and chip-eject cylinders on a CNC machining centre, with the 5 um element protecting fine spool valves and the automatic drain clearing condensate between shifts.
Supplies the diverters, pushers and bag-clamp cylinders on a carton packaging conveyor, where the regulator holds a steady setting for consistent cylinder stroke times and the lubricator keeps seals and valves running smoothly.
Installed as a point-of-use F.R.L. station at an assembly plant workstation, conditioning the air feeding air screwdrivers, clamping fixtures and small presses, with the psi gauge giving operators a local, readable line setting.
Size up by port and expected demand: the 300 size with 3/8" PT ports sits mid-range in the GC line (200/300/400/600), so step up or down if your line flow sits outside it - and because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit is already configured with the finer 5 um element (W), automatic drain (A) and a psi-scaled square gauge (F2); if you would rather have the 40 um standard element, a manual or differential-pressure drain, or a bar or MPa scale, those are decodable alternatives in the same series. The fitted reverse/check valve (K) holds downstream settings if upstream supply is interrupted.
Thread is PT as standard; G (BSPP) and NPT are catalogue options you can order - state your preference, it is a specification choice, not a delivery matter. A mounting bracket is included with this unit. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
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 figure, so we do not quote a number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
In the code GC300C10AF2WK, the A sets an automatic drain on the filter bowl (instead of the default differential-pressure or a manual drain) and the W sets the finer 5 um filter element instead of the 40 um standard. The F2 adds the embedded square gauge scaled in psi, and K fits a reverse/check valve. If you need the 40 um grade or a different drain or gauge scale, other decodable variants exist in the same GC300 series.
