The AirTAC GC300C08C2WGK AirTAC F.R.L. Combination, G1/4 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 AirTAC GC300C08C2WGK is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one set, so conditioning, regulation and lubrication are handled in a single installation. This configuration is built for 1/4 in ports with G (BSPP) threads, carries the 5 um filter element (the finer of the two published grades, against the 40 um standard), drains the filter bowl by differential pressure, and is fitted with an external round gauge reading in psi plus a reverse/check valve. The mounting bracket is included. 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 GC300 series sits in the 200/300/400/600 size range, where larger sizes take larger ports and more flow; the published options cover drain type (differential-pressure, automatic or manual), filter grade (40 um standard or 5 um with W), gauge style and scale (MPa, psi or bar), thread (PT standard, G or NPT to order) and the reverse/check valve. 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-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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element keeps particulates out of the finish and the lubricator carries a consistent oil mist to the gun's air motor.
Conditioning the shop-air feed to a machining centre's pneumatic clamps and tool-changer cylinders, with the regulator holding a steady set pressure and the psi gauge giving operators a direct readout.
Supplying the cylinders and air jets on a packaging conveyor, where the check valve holds the circuit against backflow at shut-down and the differential-pressure drain keeps the bowl clear without stopping the line.
Start with the size and port: the 300 size with a 1/4 in port suits lines where 1/4 in supply piping is the norm; step up to 400 or 600 if the circuit demands larger ports and more flow. Choose the filter element to match the duty: 40 um is the standard grade for general plant air, while the 5 um element fitted here (code W) is the choice where finer particle removal protects downstream tools and valves. The differential-pressure drain fitted here flushes the bowl automatically as the pressure differential builds, with no operator attention. The round psi gauge (scale 2) gives a familiar readout for US-style settings; MPa and bar scales are also published options. The K code adds a reverse/check valve, useful where backflow must be prevented at shut-off. Thread is G (BSPP) here; PT is the standard catalogue thread and NPT is available to order. A bracket is included for fixed mounting.
One honest note on sizing: AirTAC publishes flow only as curves, not as a single rated number, so we cannot quote a rated flow for this unit. Send us your application details and we will confirm the datasheet figures against your required flow 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-C0 regulator with a GF300-C0 filter on that branch.
AirTAC publishes flow for this series only as performance curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application details and we will confirm the datasheet flow figures against your required flow before you order.
The W code in the model number selects the 5 um element, the finer of the two published grades; 40 um is the standard element for general plant air. The 5 um grade is chosen where finer particle removal is wanted downstream, such as paint application, instrumentation or close-tolerance pneumatic tools. The same GC300 body is available with the 40 um element if your duty does not need the finer grade.
