The AirTAC GC300C08ALC2WK AirTAC F.R.L. Combination, PT1/4 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 GC300C08ALC2WK is an AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built for a 1/4 in PT port, carries a 5 um filter element for finer water and particulate removal than the standard 40 um grade, drains condensate automatically, and is the low-pressure regulator type for circuits that run below standard supply pressures. It is fitted with an external round gauge scaled in psi, a reverse/check valve, and includes a mounting bracket.
This is a genuine AirTAC part from the GC300 size class, one of four sizes (200, 300, 400, 600) that step up in port size and flow capacity. Across the range you can order different ports and thread standards (PT standard, G and NPT as options), drain types, filter grades, gauge styles and scales. Flow is published as curves rather than a single rating, so ask us to confirm the figures for 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. 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-C0 filter, GR300-C0 regulator and GL300-C0 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 the cylinders and valves of a bench pneumatic press: the 5 um element protects the valve train, the regulator holds a steady low working pressure, and the lubricator mists oil to the cylinder seals.
Conditions the air feeding spray guns on a finishing line - fine 5 um filtration and water removal upstream of the gun, regulated low pressure for the atomising circuit, and oil mist where the line's actuators need it.
Serves the air cylinders on a carton-forming and sealing conveyor: automatic drain keeps condensate out of the supply during shifts, the check valve holds the circuit if upstream pressure dips, and the lubricator feeds the actuators.
Start with the port step: this unit is the 300 size with a 1/4 in PT port; if your line needs more flow, the 400 and 600 sizes step up in port and capacity, and the 200 size steps down. Because flow is published as curves rather than a single rated figure, send us your air demand and let us confirm the right size before you order. Other decodable choices: the 5 um element (code W) versus the 40 um standard grade; automatic drain here versus manual or differential-pressure drain; PT thread standard versus G (BSPP) or NPT as order options; and gauge style and scale - this unit carries the external round gauge in psi, while the embedded square gauge in MPa, psi or bar is the alternative. The low-pressure regulator type suits circuits running below standard supply pressure; we confirm its exact adjustment range on request.
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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line's air demand and operating pressure and we will confirm the sizing against the datasheet curves on request before you order.
The W in the code is the 5 um filter element, a finer grade than the 40 um standard element, chosen where downstream valves and instruments need cleaner air. The A is the automatic drain, which expels collected condensate from the filter bowl on its own instead of relying on manual draining - useful on lines that run unattended.
