The AirTAC GC30015ALC2W 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30015ALC2W is a three-piece AirTAC GC combination unit that filters, regulates and lubricates compressed air in one assembly: a separate filter, a separate pressure regulator and a separate oil-mist lubricator. This configuration is sized 300 with a PT1/2 (1/2 in) port, PT thread as standard (G and NPT are order options), a 5 um filter element (code W, finer than the 40 um standard), an automatic drain on the filter bowl, and a low-pressure type regulator. The round gauge fitted to this code reads in psi; the embedded square gauge is the standard fitting and an external round gauge is optional. The PC (polycarbonate) bowls carry the automatic drain and the lubricator's oil-mist feed, and the regulator's set pressure is read directly off the gauge.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600 with matching port sizes, and the decodable options include drain type (differential-pressure, automatic or manual), filter grade (40 um standard, 5 um with W), gauge style and scale (MPa, psi or bar), thread (PT, G or NPT) and the low-pressure regulator type. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet figures against your application on request.

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.

Feeding spray guns and atomising headers on a finishing line, where the 5 um element protects the air supply ahead of the regulator and the lubricator carries a fine oil mist to keep gun spindles and air motors running smoothly.
Conditioning the shop-air feed to a machining centre's pneumatic actuators, tool-change cylinders and air bearings: filtered, held at a stable set pressure read on the psi gauge, and lubricated where the machine's circuit calls for oil mist.
Supplying the air cylinders that index, clamp and divert product on a packaging conveyor, with the automatic drain keeping condensate out of the line during long shifts and the low-pressure regulator matching the circuit's operating pressure.
Start with the size and port: 300 is the mid-range of the GC line (200/300/400/600), and the port steps up with size, so pick the step that matches the air demand of the circuit downstream - we can confirm the flow curve for each size on request. This code already fixes several choices: 5 um filtration (W) for finer water and particulate removal than the 40 um standard, an automatic drain so the filter bowl discharges condensate without manual attention, and a low-pressure type regulator for circuits that run below standard supply pressures. The fitted round gauge is scaled in psi; if you prefer bar or MPa, or the embedded square gauge, those are orderable variants. Thread is PT as standard - specify G (BSPP) or NPT when ordering if your pipework needs it. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing 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, not as a single rated figure, so we do not quote one number here. Tell us your application and downstream air demand, and we will confirm the datasheet flow curve for the GC300 size and check the sizing with you before you order.
Both are read from the code: A is the automatic drain, which discharges condensate from the filter bowl without manual intervention (the alternatives are the differential-pressure default and manual drain M), and W is the 5 um filter grade, finer than the 40 um standard element. The low-pressure L regulator type and the psi-scaled round gauge (C2) are also part of this configuration.
