The AirTAC GC300C10AC2WG 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC300C10AC2WG is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air from a single assembled set: a separate filter, a pressure regulator and an oil-mist lubricator. This 300-size unit is built for 3/8 in lines with G (BSPP) ports. The filter element is the fine 5 um grade (code W) for cleaner air than the standard 40 um element, the bowl drains automatically, and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). A round external gauge scaled in psi is fitted, and a mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). No reverse/check valve is fitted on this configuration.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options across 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual draining, 40 um or 5 um filtration, and gauge scale choices of MPa, psi or bar. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

Feeding spray guns and air-assisted applicators on a vehicle paint line, where the 5 um element helps keep water and particulate out of the finish, the regulator holds a steady gun pressure and the lubricator mists oil to air tools downstream.
Supplying the cylinders and actuators that drive carton erecting, case sealing and palletising stations, with filtered, regulated and lubricated air helping the valves and cylinders run consistently through long shifts.
Providing conditioned air to the clamps, tool-changers and air-blow circuits of a CNC machining cell, where stable regulated pressure and fine 5 um filtration support repeatable clamping and clean part ejection.
Start with the size and port: the 300 size with 3/8 in G ports suits lines sized for that connection, and stepping up a size gives a larger port and more flow capacity - match the step to the air demand of the downstream cylinders, tools or process rather than to the pipe alone. Choose the drain type: this unit has an automatic drain, which suits unattended or hard-to-reach installations; manual and differential-pressure drain versions are available if you prefer controlled or demand-based draining. Choose the filter grade: 40 um is the standard element for general protection, while the 5 um element fitted here (code W) is the finer option for sensitive equipment. Select the gauge scale - MPa, psi or bar - and the thread: PT is the standard, with G and NPT available as order options. A mounting bracket is included on this configuration. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so there is no one rated-flow number we can quote for this 300-size, 3/8 in unit. Tell us your application and required air demand and we will confirm the flow figures from the datasheet on request before you order.
The W in the model code GC300C10AC2WG selects the optional 5 um element instead of the standard 40 um element, giving finer removal of water and particulate for sensitive equipment. The A selects an automatic drain, so condensate is expelled without manual attention - useful where the unit is mounted in a cramped or infrequently visited position. A 40 um element and manual or differential-pressure draining are available as alternative configurations.
