The AirTAC GC300C08AC2G AirTAC F.R.L. Combination Unit, 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 GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-preparation set. This configuration, GC300C08AC2G, is the size 300 unit with a G1/4 (1/4 in) port and G thread. The filter section carries a 40 um element with an automatic drain, so collected condensate is expelled without manual attention. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi) and is fitted with an external round gauge reading in psi, while the lubricator delivers an oil mist to downstream pneumatic components. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and the polycarbonate bowls suit indoor compressed-air service. A mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT (standard), G or NPT threads to order. Flow is published by the manufacturer as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Feeds spray guns and air-assisted applicators at a body shop: the filter removes water and particulate, the regulator holds a steady gun pressure read on the psi gauge, and the lubricator mists oil to the gun's air motor.
Prepares the air supply for the stopper, pusher and lift cylinders along a bottling conveyor, keeping moisture and debris out of the valves while the lubricator extends cylinder seal life.
Conditions the air feeding pneumatic clamps and swing cylinders on a CNC machining fixture, where the regulator holds a repeatable clamping pressure and the automatic drain keeps condensate out of the circuit.
Start with the port size: this unit is size 300 with a 1/4 in port, and the larger the size (200/300/400/600) the larger the port and the greater the flow capacity. Choose the drain to match service: automatic drain (fitted here) suits unattended installations, manual drain suits periodically checked points, and differential-pressure drain is the catalogue default. The standard 40 um element covers general pneumatic supply; specify the 5 um W grade where finer particulate removal is needed. The round gauge here reads in psi; MPa and bar scales are also available. Thread is G (BSPP) on this model, with PT as the standard and G/NPT as orderable options, and a mounting bracket is included. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application 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 GC series as curves rather than a single rated figure, so no single l/min or SCFM number is quoted here. Tell us your application and we will confirm the flow and datasheet figures for this size 300, 1/4 in unit on request.
The filter section of this model carries the A (automatic) drain code, so condensate is expelled without anyone opening the bowl - useful for units mounted out of easy reach. The catalogue also offers manual drain (code M) and differential-pressure drain (blank) as orderable alternatives on the same size.
