The AirTAC GC30015AF2WGK AirTAC F.R.L. Combination Unit 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015AF2WGK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit for compressed-air lines. This configuration is built around a 1/2 in (G1/2) port with G thread, a 5 um filter element, an automatic drain on the filter bowl, a standard regulator with an embedded square gauge reading in psi, and a fitted reverse/check valve. The mounting bracket is included, and the polycarbonate bowls suit the 300 size. It filters water and particulate from the air, holds a set downstream pressure, and meters oil mist into the stream to lubricate downstream tools and actuators.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in. Options across the series include manual or differential-pressure drains, a 40 um standard element, alternative gauge scales, and PT or NPT threads in place of G. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet figures 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: GF300-15 filter, GR300-15 regulator and GL300-15 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 spray guns and air-assisted applicators on a paint line, where the 5 um element, regulated pressure and oil mist keep finish quality consistent across a shift.
Supplying grippers, pushers and stopper cylinders on a filling line, with the check valve holding the set pressure and the lubricator keeping cylinder seals working smoothly.
Powering pneumatic clamps and tool-change cylinders on a machine tool, where the regulator holds a steady clamp pressure and the psi gauge gives operators a direct readout.
Choose the GC size by the port and flow step your line needs: this 300 unit carries a 1/2 in G1/2 port; smaller 200 units step down to 1/8-1/4 in and larger 400/600 units step up to 3/4-1 in. Within the size you can pick the drain (automatic, as fitted here, manual, or differential-pressure), the filter element (5 um as specified here, or the 40 um standard), the gauge scale (MPa, psi or bar; this unit reads psi on the embedded square gauge, with an external round gauge optional), the thread (G as coded here, with PT as the standard and NPT as a catalogue option), the reverse/check valve, and whether a bracket is included. Flow is published as curves rather than a single rated number, so send us your application details and we will confirm sizing 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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated number, so we do not quote a figure such as l/min or SCFM. Tell us your line pressure and the flow your application needs, and we will confirm the sizing from the datasheet on request.
The A in the code means the filter bowl drains itself automatically, so the unit does not depend on someone opening a manual drain. The GC series also offers a manual drain and a differential-pressure drain; the 40 um standard element can be substituted for the 5 um element fitted here, and the thread can be ordered in PT or NPT instead of the G (BSPP) specified.
