The AirTAC GC300C15ALC2GK AirTAC F.R.L. Combination, G1/2, Low-Pressure 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled into one prepared-air station. This GC300C15ALC2GK is the size 300 unit with a G1/2 (BSPP) port. It strips water and particulate down to the standard 40 um grade, holds downstream pressure with the low-pressure type regulator, and meters oil mist into the air line. The automatic drain opens the filter bowl by itself, the external round gauge reads in psi, and a reverse/check valve is fitted. The bowls on this unit are metal, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and catalogue options for manual or automatic draining, a 5 um filter element (code W), gauge style and scale, G or NPT threads, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm sizing 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.

Feeds filtered, regulated and lubricated air to the pneumatic clamps and tool-change cylinders on a machining centre, with the psi gauge giving the operator a direct setpoint readout.
Prepares supply for the cylinders and air grippers on a carton-forming or case-packing conveyor, where the automatic drain keeps condensate out of the valves through long shifts.
A prepared-air drop on an assembly-plant ring serving impact wrenches and fixture cylinders; the lubricator carries oil mist to the tools and the low-pressure type regulator suits circuits run at reduced pressure.
Start with the port step: size 300 carries 1/2 inch ports, and the GC range steps through 200, 300, 400 and 600 as air demand rises - match the size to your line's consumption and we will confirm the flow curve for the exact model. On this unit the drain is automatic, so the filter bowl needs no daily manual bleeding; manual and differential-pressure drain versions exist if you prefer. The filter grade is the standard 40 um element; specify code W for 5 um where finer filtration matters. The regulator here is the low-pressure type - confirm its adjustment range with us, since the standard-type range does not apply to this variant. The gauge is the external round type reading in psi; the embedded square gauge and MPa or bar scales are the other catalogue choices. Thread is G (BSPP); PT is the standard thread and NPT is orderable. A mounting bracket is included.
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 number here. Tell us your line's air consumption and working pressure and we will confirm the flow curve and sizing for GC300C15ALC2GK from the datasheet before you order.
The L code in GC300C15ALC2GK selects the low-pressure regulator variant rather than the standard one; its exact adjustment range is not published in our material, so confirm the range with us against your setpoint before ordering. The rest of the code decodes as: G1/2 port, G thread, automatic drain, 40 um element, round psi gauge, check valve fitted, bracket included.
