The AirTAC GC300C08F2G 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 GC300C08F2G is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set for 1/4 in (G1/4) pipework with G thread. The filter element is the standard 40 um grade and the bowl drains by differential pressure, so condensate is expelled as the pressure differential builds during operation. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi) and carries an embedded square gauge reading in psi, so downstream pressure can be set and monitored at a glance. The lubricator meters oil mist into the air stream for downstream pneumatic tools and actuators. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowls on this size are polycarbonate, and a mounting bracket is included.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with matching port sizes, so the same combination concept scales from small point-of-use drops up to high-flow plant air. Across the range you can order alternative drain types (automatic or manual), a finer 5 um filter element (code W), gauge scales in MPa, psi or bar, and G or NPT thread options. Rated flow for this series is published as curves rather than a single figure, so ask us and we will confirm the datasheet and flow data for your application on request.

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.

Point-of-use preparation at a machining cell: the filter removes water and swarf-carrying particulate, the regulator holds a steady setting for pneumatic clamps and chucks, and the lubricator feeds mist to air tools on the same drop.
Feeding the cylinders and actuators on a carton-forming and sealing conveyor, where the 40 um element protects valve spools, the regulator keeps cylinder speed consistent, and the lubricator extends seal and O-ring life.
A workbench station supplying impact wrenches, ratchets and air screwdrivers: clean, regulated and lubricated air at one G1/4 connection keeps hand tools running through a full shift without inline oiling by operators.
Start with the size and port: the 300 size with a 1/4 in port suits compact point-of-use drops, while larger sizes 400 and 600 move more air - match the size to the flow your circuit actually needs rather than to the pipe alone. Then choose the drain: this unit uses the differential-pressure drain (the default); automatic or manual drains are available in the series if you prefer hands-off or scheduled draining. The 40 um element is standard; specify the W code for the 5 um grade where finer filtration is required. Gauge scale can be psi (as fitted here), MPa or bar, and thread can be ordered in G or NPT instead of the PT standard. A mounting bracket is included with this configuration. Because rated 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the datasheet and the relevant flow-curve data for this 300-size, G1/4 unit on request.
Yes. Differential-pressure draining is the default on the GC series and is what this configuration carries, but the same 300-size combination can be ordered with an automatic drain for hands-off condensate removal or a manual drain for scheduled draining. Note that the regulator adjustment range depends on the drain type: 0.15-0.9 MPa (20-130 psi) with the automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with the manual drain.
