The AirTAC GC300C10AF2WGK 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This GC300C10AF2WGK is built in the 300 size with a G3/8 (BSPP) port. The filter element is the fine 5 um grade (the W option) for cleaner air than the standard 40 um element, the bowl drains automatically so collected condensate is expelled without manual attention, and the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). An embedded square gauge graduated in psi is fitted, a reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC range is offered in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge scale options, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeds filtered, regulated and lubricated air to pneumatic clamps, tool-changer cylinders and chip-clearing blow-off on a machining centre, with the 5 um element protecting close-tolerance valves.
Prepares air for carton-forming, sealing and case-packing cylinders on a packaging conveyor, where the lubricator maintains oil mist for cylinder and valve service life and the automatic drain suits multi-shift running.
A central air-preparation point for grippers, press cylinders and rotary actuators on an assembly line, with the psi gauge giving operators a readable setpoint and the check valve holding downstream pressure during supply dips.
Choose the size step (200/300/400/600) and its matching port against the air demand of the line - this 300 unit carries a 3/8 in port. Drain choice matters: automatic drain (fitted here) suits unattended or hard-to-reach installations, manual drain suits stations checked daily, and the differential-pressure default drains on a pressure drop. The 5 um element fitted here is the right pick for valves, cylinders and instruments that need finer filtration than the 40 um standard. Gauge scale is selectable (MPa, psi or bar) and this unit carries the square psi gauge; the reverse/check valve holds downstream pressure if the supply is interrupted. PT is the standard thread, with G and NPT available as order options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, 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 GC300 as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line pressure and air demand and we will confirm the sizing against the datasheet on request before you order.
The W code in the model sets the fine 5 um element instead of the 40 um standard, which suits downstream valves, cylinders and instruments that need cleaner air. The A code sets the automatic drain, so condensate is expelled from the bowl without daily manual draining - useful on unattended or multi-shift installations.
