The AirTAC GC30015C2WK 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 PT1/2" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015C2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is size 300 with a PT1/2 (1/2 in) port, PT thread as standard. The filter element is the fine 5 um grade (code W) with a differential-pressure drain, so water and particulate are removed before air reaches downstream tools. The standard regulator adjusts from 0.15-0.9 MPa (20-130 psi), with a round psi gauge fitted, and the set includes a reverse/check valve (code K) to hold downstream pressure if the supply drops. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The filter and lubricator bowls on this size are polycarbonate (PC).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, plus options such as 40 um or 5 um filtration, automatic, manual or differential-pressure drains, gauge type and scale, and G or NPT thread variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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: GF300-15 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.

Finely filtered, regulated and lubricated air feeds spray guns and air-assisted applicators on a paint line, keeping water, scale and oversize particles out of the finish while the regulator holds a steady gun pressure.
On a carton-forming and sealing conveyor, the combination conditions the air feeding the pneumatic pushers and clamp cylinders, with the check valve helping hold the set pressure if the main supply dips.
A machine-tool cell uses the set to prepare air for workholding clamps, tool-change actuators and air-powered fixtures, where clean, dry, correctly lubricated and closely regulated supply protects the downstream components.
Start with the port and size step: this unit is size 300 with a PT1/2 port; if your line needs more or less air, the GC family steps through sizes 200/300/400/600 with ports from 1/8 in to 1 in. Choose the drain to suit maintenance access: differential-pressure (this unit), automatic, or manual. Choose the filter grade: 40 um standard or 5 um (W) for finer protection - this unit carries the 5 um grade. The regulator on this set is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range and a round psi gauge; square embedded gauges and MPa/psi/bar scales are the catalogue alternatives. Thread is PT as standard, with G (BSPP) and NPT available as order options; a mounting bracket is included, and the K code confirms a reverse/check valve is fitted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the relevant flow figures from the datasheet on request before you order.
The W in the code GC30015C2WK selects the optional 5 um filter element instead of the standard 40 um grade, for finer protection of downstream equipment. The K selects a reverse/check valve, which helps hold the downstream set pressure if the upstream supply is interrupted. Both are catalogue options; the drain on this unit is the differential-pressure type, and the round gauge reads in psi.
