The AirTAC GC300C15ALF2WK 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 GC series is AirTAC's three-piece F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-treatment stack. This GC300C15ALF2WK is built for 1/2 in PT ports and carries the 5 um filter element (code W) instead of the standard 40 um, an automatic drain that ejects collected condensate without manual attention, a low-pressure regulator, an embedded square gauge reading in psi, and a reverse/check valve. The bowl is metal, a mounting bracket is included, 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 range spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options for thread type (PT standard, with G and NPT as order choices), drain type, filter grade, gauge scale and check valve. Flow is published as curves rather than a single rated figure, 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.

Conditioning the 1/2 in air feed to a bench pneumatic press: water and particles down to 5 um are removed, downstream pressure is held at a low setpoint, and the cylinders receive a fine oil mist.
Supplying treated air to the pick-and-place cylinders and grippers on a packaging conveyor, where the automatic drain keeps condensate out of the valves through continuous shifts.
Feeding impact wrenches and air ratchets at a truck-service drop: filtered, low-pressure regulated air plus lubrication keeps the tools running through the working day.
Step up or down through the GC sizes (200 / 300 / 400 / 600) to match the port and the air demand of your line; this unit sits at size 300 with a 1/2 in PT port. Choose the drain: automatic (fitted here) for installations that are not checked daily, manual for controlled blow-down, or differential-pressure as the default. Pick the 40 um standard element or the finer 5 um W grade fitted here. Gauge scale is selectable (MPa, psi or bar; this unit reads psi), the regulator is the low-pressure L variant, and thread can be ordered as G or NPT instead of PT. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing against 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 curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your line pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet on request.
The L code in GC300C15ALF2WK marks the low-pressure regulator variant, intended for lower downstream setpoints than the standard type. The exact adjustment range for this variant is not published in our current data, so we confirm it on request before you order.
