The AirTAC GC30015ALC2WK AirTAC F.R.L. 1/2 in FRL Combination Unit 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one complete air-preparation set. This configuration, GC30015ALC2WK, is the 300 size with a PT1/2 (1/2 in) PT thread. The filter element is the fine 5 um grade (W) with an automatic drain, so collected water is expelled without manual attention. The regulator is the low-pressure type (L) for circuits that run at lower set pressures, and it is fitted with an external round gauge reading in psi. A reverse/check valve (K) is fitted, and the set includes a mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade, gauge style and scale, thread form (PT standard, G and NPT as order options) and bracket. Flow is published as curves rather than a single rating, 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds filtered, regulated and lubricated air to a machining centre's pneumatic clamps and tool-change cylinders. The 5 um element protects fine valve spools from particulate and water, the automatic drain keeps the bowl clear during unattended shifts, and the low-pressure regulator type suits circuits that hold lower set pressures.
Supplies the air cylinders and air-driven diverters on a packaging or conveyor line. The lubricator mists oil downstream to keep cylinder seals and valve seats working smoothly, the regulator holds a steady line pressure for consistent cycle behaviour, and the round psi gauge lets operators read the setting at a glance.
Prepares air for the lower-pressure actuation circuits on a bottling or filling line, where the low-pressure regulator type is the right match for reduced set pressures. The check valve holds the downstream circuit if upstream supply dips, and the automatic drain removes condensed water before it reaches the machine's valves.
Start with the size and port: 300 is the mid-range frame, and the 15 code gives a 1/2 in PT port - step up to 400 or 600 if your line's air demand is high, or down to 200 if the circuit is small. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering. This unit already fixes several choices: 5 um filtration (W) instead of the 40 um standard element, an automatic drain instead of manual or differential-pressure, the low-pressure regulator type, and a round psi gauge. If you would prefer the 40 um element, a different drain, a square embedded gauge, or MPa or bar scale, those are decodable alternatives within the same family. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order. A bracket is included with this code, and the reverse/check valve is fitted.
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 this series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and operating pressure and we will confirm the flow and datasheet figures for this exact configuration on request before you order.
L is the low-pressure regulator type. It is intended for circuits that need lower set pressures than the standard-type regulator is aimed at. The exact adjustment range for the low-pressure type is not published in the sheet we work from, so please confirm the range with us on request. Everything else in this code decodes as: 300 size, PT1/2 port, PT thread, automatic drain, 5 um filter element, round psi gauge, reverse/check valve fitted, bracket included.
