The AirTAC GC30008AC2G 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 PT1/4" ports, a 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008AC2G is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter removes water and particulate down to 40 um, a standard regulator holds downstream pressure anywhere in the 0.15-0.9 MPa (20-130 psi) range, and a lubricator feeds oil mist to downstream tools and actuators. This 300-size unit is fitted with G1/4 ports, an automatic drain that expels collected condensate without manual attention, a round pressure gauge reading in psi, and a mounting bracket. The filter and lubricator bowls are polycarbonate, and the unit handles a maximum inlet pressure of 1.0 MPa (145 psi) at temperatures from -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, and can be ordered with manual or differential-pressure drains, a 5 um filter element (code W), square or round gauges in MPa, psi or bar scales, a reverse/check valve, and PT, G or NPT threads. 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 filtered, regulated and lubricated air to a machining centre's pneumatic tool-changer and clamping circuits, where the automatic drain keeps condensate out of the valves during unattended shifts.
Conditioning the air supply to conveyor diverters, carton-formers and sealing cylinders on a packaging line, with the lubricator extending cylinder and valve service life.
A point-of-use F.R.L. at an assembly workstation, delivering clean, pressure-regulated, oil-misted air to air screwdrivers, impact drivers and small pneumatic presses.
Start with the size and port: the 300 frame with G1/4 ports suits lines where the required flow sits above the 200 class but a compact footprint still matters - size up to 400 or 600 if your demand is higher. The automatic drain on this unit suits unmanned or hard-to-reach installations; choose manual drain where you prefer controlled, scheduled blowdown, or differential-pressure drain where you want discharge tied to the pressure drop across the element. The standard 40 um element is right for general plant air; specify the 5 um grade (code W) only where downstream equipment needs finer filtration. The round gauge on this unit reads in psi; square gauges and MPa or bar scales are available. PT is the standard thread, with G and NPT as order options, and a mounting bracket is included.
Because flow is published as curves rather than a single rating, we do not quote a rated flow number here. Send us your application details and we will confirm sizing against the datasheet curves 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 GR300-08 regulator with a GF300-08 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a flow number here. Send us your application's flow and pressure requirements and we will confirm the correct size against the datasheet curves on request.
The A in the code GC30008AC2G specifies an automatic drain, which expels collected condensate from the filter bowl without operator attention - useful for unmanned or hard-to-access installations. The GC series is also available with a manual drain or the default differential-pressure drain if you prefer a different discharge method.
