The AirTAC GC300C15ALC2WGK AirTAC F.R.L. Combination, G1/2 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 GC300C15ALC2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prepared-air station. This size-300 unit is configured with a G1/2 (BSPP) port, a 5 um filter element (the finer of the two catalogue grades) with an automatic drain that expels collected condensate without manual attention, a low-pressure-type regulator, a round pressure gauge reading in psi, a reverse/check valve fitted on the regulator, and a mounting bracket included. It conditions compressed air in one pass: water and particulate are removed, downstream pressure is held at your set point, and a fine oil mist is carried to the air tools and cylinders it feeds.
This is a genuine AirTAC part. The GC line is published in sizes 200, 300, 400 and 600 with a choice of PT, G or NPT thread, differential-pressure, automatic or manual draining, 40 um or 5 um filtration, standard or low-pressure regulation, and gauge scale options. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details against 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 the clamping fixtures, tool-changer cylinders and pneumatic actuators on a machining centre, with the 5 um element protecting fine pilot valves from particulate carryover.
Mounted at the head of a packaging or bottling line to condition the air feeding gripper cylinders, diverters and case-packing actuators, holding a steady set pressure while the automatic drain keeps condensate off the line during continuous shifts.
Installed on a process skid to prepare air for pneumatic quarter-turn valve actuators and positioner circuits, with the check valve holding the downstream circuit if supply pressure dips and the psi gauge giving operators a local reading.
Start with the port and size step: this unit is size 300 with a G1/2 port; the GC family steps through 200, 300, 400 and 600 with ports from 1/8 in to 1 in, so pick the step that matches your line's pipe size and air demand. Because flow is published as curves and not a single rated figure, ask us to confirm the sizing against your application before ordering. Other decodable choices on this configuration: the 5 um element (code W) instead of the 40 um standard, the automatic drain instead of manual or differential-pressure, the low-pressure-type regulator instead of the standard type, the round external gauge with a psi scale (MPa and bar scales are the alternatives), the fitted reverse/check valve, and the included mounting bracket. Thread is G (BSPP) here; PT is the standard catalogue thread and NPT is also an orderable option.
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, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your working pressure and air demand and we will confirm the correct size from the datasheet curves before you order.
The L in the code marks the low-pressure-type regulator rather than the standard type, intended for circuits set below the standard regulator's range. The exact adjustment range for this variant is not published in a single figure, so confirm your set pressure with us and we will verify suitability from the catalogue before ordering.
