The AirTAC GC300C10AC2WK AirTAC F.R.L. Combination, PT3/8, 5 um 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 air-treatment stack. This GC300C10AC2WK is built on the size 300 body with a 3/8 in PT port. The filter element is the fine 5 um grade (the W option, against the standard 40 um) with an automatic drain, so collected condensate is discharged without manual attention. The standard regulator adjusts over 0.15-0.9 MPa (20-130 psi) and this configuration carries a round pressure gauge scaled in psi. A reverse/check valve is fitted, the bowl on this unit is metal, and the mounting bracket is included.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and check-valve options. Flow is published by AirTAC as selection curves rather than a single rated figure, so ask us to confirm the flow and 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 cleaned, regulated and lubricated air to a machining centre's pneumatic clamps and tool-change cylinders, with the 5 um element protecting fine valves from particulate carryover.
Supplying the air cylinders on a carton-forming and sealing conveyor, where the automatic drain handles condensate during continuous shifts and the lubricator mists the actuator seals.
A treatment stack at the point of use on a plant air drop, regulating downstream pressure for impact wrenches and air ratchets while the psi gauge gives operators a local reading.
Start with the port and size step: this unit is size 300 with a 3/8 in PT port; if your line runs larger bore piping, the 400 or 600 sizes step up in port and handling capacity, while size 200 steps down. Choose the drain to match maintenance access: automatic drain (as fitted here) discharges condensate on its own, manual drain suits attended installations, and the differential-pressure default drains on a pressure drop. Filtration is 5 um here; the standard grade is 40 um if finer filtration is not required. The gauge can be ordered round or square, scaled in MPa, psi or bar - this unit is round, psi. Thread is PT as standard, with G (BSPP) and NPT available as order options, and a bracket is included for panel or wall mounting.
Because AirTAC publishes flow as curves rather than a single rated number, we do not quote a flow figure here. Send us your application details and we will confirm sizing against the datasheet curves 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 this series as selection curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the flow from the datasheet curves on request before you order.
The W code in the model sets the fine 5 um element instead of the standard 40 um grade, which suits downstream valves and sensitive actuators. The A code sets the automatic drain, so the filter bowl discharges collected condensate by itself instead of waiting for a manual drain visit.
