The AirTAC GC300C15AF2WK AirTAC F.R.L. Combination, PT1/2 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 GC300C15AF2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator assembled as one air-preparation set. This configuration is the size 300 unit with a PT1/2 (1/2 in) PT thread port, a 5 um filter element (code W), an automatic drain on the filter bowl, an embedded square gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. In use, the filter removes water and particulate down to 5 um, the regulator holds a steady downstream pressure adjustable from 0.15 to 0.9 MPa (20-130 psi), and the lubricator feeds an oil mist to downstream air tools and cylinders. The maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). At size 300, the filter and lubricator bowls are polycarbonate (PC).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with matching port sizes, and each set can be ordered with a different drain type, filter grade (40 um standard or 5 um), gauge scale (MPa, psi or bar), thread option (PT standard, with G and NPT as catalogue options) and reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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 spray booths and finishing stations on a plant air main: the 5 um element and auto drain keep water and grit out of the paint air, the regulator holds a steady gun pressure, and the lubricator is run dry-side or oil-side as the line requires.
Supplies carton sealers, case packers and bagging heads fed from a 1/2 in drop: clean, regulated air keeps actuator strokes consistent shift after shift, while the oil mist extends the life of the machine's air cylinders and valves.
Prepares the air feeding tool clamps, chip-blow nozzles and pallet-clamp cylinders on a machining centre: the regulator pins the clamping pressure, the automatic drain protects the cell from condensate carryover, and the psi gauge gives operators a visible setpoint.
Start with the size and port: the GC series steps through sizes 200, 300, 400 and 600, and the port rises with size - here size 300 gives a PT1/2 (1/2 in) PT thread connection. Match the size step to the air consumption of the machines downstream, then confirm it against the published flow curves before ordering. Next choose the drain: this unit has the automatic drain (code A), which discharges collected condensate without manual attention; manual and differential-pressure drains are the other catalogue choices. Filter grade is 5 um on this unit (code W) against the 40 um standard element - pick 5 um where downstream equipment needs finer particulate removal. The square gauge fitted here reads in psi; MPa and bar scales are also available, and an external round gauge is an option. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and a reverse/check valve (code K) is fitted to hold downstream pressure if the supply drops. 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 application details and we will confirm the datasheet figures and check the sizing against your demand 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 curves rather than a single rated figure, so we do not quote a flow number for this unit. Tell us your operating pressure and the air consumption of the equipment downstream, and we will confirm the datasheet flow curves and check the sizing of the GC300 against your application on request.
The A in GC300C15AF2WK is the drain code: this filter bowl drains condensate automatically, so it suits drops that are not checked daily. The catalogue also offers a manual drain (code M) and a differential-pressure drain (blank) on the same size, so you can order the GC300 with whichever drain type matches how the installation is maintained.
