The AirTAC GC300C15C2W 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 GC300C15C2W is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one filtered-air package. This configuration is built for 1/2 in PT ports, carries the 5 um filter element (code W) instead of the standard 40 um, and drains its filter bowl by differential pressure. The standard regulator is fitted with an external round gauge reading in psi, a check/reverse valve is not fitted, and a mounting bracket is included. The filter and lubricator bowls on this 300 size are polycarbonate, and the unit is rated for a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual bowl drains, 40 um or 5 um filtration, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. 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.

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 clean, regulated and lubricated air to the pneumatic valves, clamps and tool-change cylinders on a CNC machining centre, where the 5 um element protects fine pilot valves from particulate carryover.
Conditioning the supply at a drop point on an assembly-plant ring main so impact wrenches, nutrunners and air ratchets receive filtered, pressure-stabilised, oil-misted air for consistent tool life.
Serving the pneumatic cylinders and diverters on a carton packaging and conveyor line, where one combined filter-regulator-lubricator point keeps the whole downstream circuit conditioned from a single 1/2 in drop.
Start with the port and size: this unit steps up to 1/2 in PT ports on the 300 frame, so match it to the line size and air demand of the circuit it feeds. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. Choose the drain to suit access: differential-pressure (as fitted here) drains automatically while the unit works, automatic suits unattended installations, and manual suits supervised points. Choose 5 um filtration, as on this model, when downstream equipment needs finer particle removal than the 40 um standard. Gauge scale (MPa, psi or bar), square or round gauge style, thread option (PT standard, G or NPT to order) and bracket choice are all decodable from the code - this one carries a round psi gauge and includes the bracket.
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 no single l/min or SCFM number can be quoted honestly. Tell us your line pressure and air demand and we will confirm the flow curve and correct sizing from the datasheet on request.
The W in the code GC300C15C2W selects the optional 5 um filter element in place of the 40 um standard, giving finer particulate removal for sensitive downstream equipment. The C2 selects an external round gauge reading in psi; embedded square gauges and MPa or bar scales are the alternative catalogue options.
