The AirTAC GC300C10MC2WG 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 GC300C10MC2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set. This configuration is the 300 size with a G3/8 (BSPP) port, fitted with the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, a manual drain on the filter bowl, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and the lubricator delivers oil mist downstream to keep air tools and cylinders running. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). A mounting bracket is included; no reverse/check valve is fitted.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with a choice of port sizes, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, and gauge type and scale options. Flow figures for this series are published as curves rather than a single rated number, so ask us and we will confirm the datasheet and sizing for your application before you order.

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 clean, regulated and lubricated air to the solenoid valves, clamps and cylinders that actuate workholding and tool changes on a machining centre, with the 5 um element protecting fine pilot circuits.
Conditioning the air feed at a bench or line station where impact wrenches, nutrunners and air ratchets work continuously; the lubricator's oil mist keeps the tool motors from running dry.
Supplying the air cylinders on case packers, carton sealers and palletisers, where the regulator holds a steady setting as machines cycle and the filter sheds water picked up in the main header.
Start with the size and port: the 300 body with its 3/8 in port suits mid-range pneumatic circuits, and stepping up to 400 or 600 gives more flow capacity at the same line pressure. Choose the drain to match the installation: this unit has a manual drain (code M), which is simple and dependable but needs someone to drain the bowl periodically; automatic or differential-pressure drains suit unmanned installations. This unit carries the 5 um element (code W) instead of the 40 um standard, which is worthwhile where finer particulate matters. The gauge here is the external round type with a psi scale; embedded square gauges and MPa or bar scales are alternatives. Thread is G (BSPP) on this code, with PT as the catalogue standard and NPT orderable. A mounting bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a flow number here. Send us your line pressure and expected air demand and we will confirm the right size 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 GR300-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for the GC series as performance curves rather than a single rated figure, so we do not state a flow number here. Send us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The M code means the filter bowl is drained by hand: someone opens the drain periodically to release collected water. If the unit will sit in an unmanned installation, the automatic (A) or differential-pressure (blank) drain options are worth considering instead. Note that with a manual drain the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
