The AirTAC GC300C08AF2WGK AirTAC F.R.L. Combination, G1/4 Port 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator assembled as one supply unit. This GC300C08AF2WGK is built for 1/4 in ports with G (BSPP) thread, filters to 5 um to strip water and fine particulate, drains condensate automatically, carries an embedded square pressure gauge reading in psi, and includes a reverse (check) valve so downstream pressure is held if the supply dips. Mounting bracket included.
This is a genuine AirTAC part from the GC300 size class, one of four sizes (200/300/400/600) with port options from 1/8 to 1 in and PT, G or NPT threads. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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.

One point of supply feeding filtered, regulated and lubricated air to spray guns and air-driven finishing equipment, where the 5 um element supports finish quality.
Conditions the air feeding the cylinders and grippers on a carton packing conveyor, with the regulator set to the machine's working pressure and the lubricator misting the actuator circuit.
Supplies regulated, lubricated air to pneumatic clamps and tool-change actuators on a machining centre, with the check valve holding the circuit if the shop supply dips.
Size and port: 300 is the mid-range GC frame on a 1/4 in G-threaded port; step up or down a size when your air demand calls for it. Filtration: this code carries the 5 um element (W) instead of the standard 40 um grade, for finer protection of downstream equipment. Drain: automatic here; manual and differential-pressure drains are the other catalogue choices. The square gauge reads psi, with MPa and bar scales available, and an external round gauge is an option. Thread: G (BSPP) on this code, while PT is the standard thread and NPT is also offered. Bracket included. Flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for the GC300 as curves, not as a single rated figure, so we do not quote a number here. Tell us your working pressure and air demand and we will confirm the sizing from the datasheet on request.
The W code selects the 5 um filter element instead of the standard 40 um grade, for finer protection of downstream tools and actuators. The A code fits the automatic drain, so condensate is expelled without manual attention; manual and differential-pressure drains are the other options.
