The AirTAC GC300C08MC2WGK 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 GC300C08MC2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is built for a G1/4 (1/4 in) port, filters to 5 um instead of the 40 um standard element, and uses a manual drain you open by hand. The regulator is the standard type with an adjustment range of 0.05-0.9 MPa (7-130 psi), a round psi gauge is fitted, and a reverse/check valve is included. The filter bowl on this 300 size is polycarbonate (PC), and a mounting bracket is supplied.
It is a genuine AirTAC part. The GC range is offered in 200, 300, 400 and 600 sizes covering ports from 1/8 to 1 in, with PT as the standard thread and G or NPT available to order, plus choices of drain type, filter grade, gauge scale and reverse/check valve. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm datasheet figures against 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.

Installed ahead of a CNC machining cell, the GC300C08MC2WGK removes water and 5 um particles from shop air, holds a set pressure for clamping circuits and meters oil mist to spindle and tool-change actuators on a G1/4 line.
On a packaging line, the combination conditions the air feeding carton-forming and sealing cylinders: filtered and regulated supply keeps cylinder strokes consistent while the lubricator delivers oil mist to cylinders and directional valves.
At bench assembly stations running impact drivers and air ratchets, the set gives each operator a filtered, regulated and lubricated G1/4 drop, with the round psi gauge for at-a-glance checks of the working pressure.
Start from the port and size: this is the 300 size with a G1/4 port, and the larger 400 and 600 sizes carry bigger ports and more flow capacity, so step up if your line demand is high. Filter grade is a real choice: 40 um is standard and the W code selects the finer 5 um element fitted here. Drain type is another: differential-pressure is the default, with automatic (A) and manual (M) available - this model has the manual drain. Gauges come as the embedded square type or an external round gauge in MPa, psi or bar scales; this unit carries the round psi gauge. Thread is G here, with PT as standard and NPT to order, and a mounting bracket is included. Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your application 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 the GC300 as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure and expected air consumption and we will confirm the sizing against the datasheet before you order.
The W in GC300C08MC2WGK selects the optional 5 um filter element instead of the 40 um standard, and M selects a manual drain you open by hand instead of the differential-pressure drain fitted as default. Both are catalogue choices on the GC300; ask us if you would prefer the 40 um element or an automatic drain.
