The AirTAC GC300C15C2WK AirTAC F.R.L. Combination, PT1/2, 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 GC300C15C2WK is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-treatment stack. This configuration is the size 300 unit with PT1/2 ports, 5 um filtration (the W grade, finer than the 40 um standard element), differential-pressure draining of the filter bowl, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, a round external gauge with a psi scale, a reverse/check valve fitted, and the mounting bracket included. In service it removes water and particulate from the compressed air, holds a set downstream pressure, and adds a controlled oil mist for air-driven tools and cylinders.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread form (PT standard; G and NPT as order options) and check valve. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 a bank of impact wrenches, ratchets and air cylinders at an assembly station: the filter stage strips water and 5 um particulate, the regulator holds a steady tool pressure, and the lubricator carries oil mist to keep the tools running shift after shift.
Supplying the cylinders and air grippers on a carton-forming or case-packing conveyor: conditioned air protects the valve islands, the set pressure keeps motion repeatable, and the oil mist lubricates the cylinder seals for long service life.
Powering the clamps, tool-change cylinders and air blast on a machining centre: the 5 um grade guards the clamping valves from fine contamination, the regulator pins the clamp pressure, and the check valve holds the circuit against supply dips.
Start with the size and port: the 300 size with PT1/2 ports sits in the middle of the GC range, and the right step depends on the air consumption of the machines downstream - ask us to check the published flow curves against your demand before ordering. The 5 um element (code W) suits applications that need finer particulate removal than the 40 um standard; both grades are available across the family. Drain choice is differential-pressure (this unit, the default), automatic or manual; the differential-pressure drain discharges collected condensate when the pressure differential across the element rises. The regulator here is the standard type with a 0.15-0.9 MPa (20-130 psi) range, fitted with a round external gauge on a psi scale (MPa and bar scales, and the embedded square gauge, are the catalogue alternatives). Thread is PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included; a reverse/check valve is factory-fitted on this code.
Because AirTAC publishes flow as curves rather than a single rating, send us your line pressure and air demand and we will confirm the correct 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, not as a single rated number, so there is no one figure we can quote. Send us your working pressure and the air consumption of the equipment downstream, and we will confirm the sizing from the datasheet on request.
The differential-pressure drain is the default drain on the filter bowl: it discharges collected condensate automatically when the pressure drop across the filter element rises to a set level, with no manual blowing down. The 5 um element is the W grade - a finer filtration option than the 40 um standard element - chosen on this code for applications that need cleaner air downstream.
