The AirTAC GC300C08AF2WG 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built up as one working unit. This GC300C08AF2WG is the size 300 set with a G1/4 port, fitted with an automatic drain on the filter bowl, a 5 um filter element (the finer of the two catalogue grades), a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), and an embedded square gauge reading in psi. A mounting bracket is included; no reverse/check valve is fitted.
It is a genuine AirTAC part for compressed air, rated up to 1.0 MPa (145 psi) inlet and -5 to 70 C (non-freezing). The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, with options for thread (PT is the standard; G and NPT are catalogue options), drain type, filter grade and gauge scale. Flow is published as curves rather than a single rating, so ask us to confirm the sizing figures and datasheet 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.

Feeding impact wrenches, nutrunners and air cylinders at an assembly station with filtered, regulated and lubricated air from a single G1/4 drop.
Supplying the stopper, pusher and lift cylinders along a packaging conveyor, where the 5 um element protects directional valves and the lubricator keeps cylinder seals moving.
Regulating and lubricating air to clamps, tool-change cylinders and blow-off nozzles on a machining centre, with the psi gauge giving operators a local setpoint check.
Size 300 with a 1/4 in port sits mid-range in the GC family (200/300/400/600, 1/8 to 1 in); step up or down a size when your air demand changes - we can check the published flow curves against your consumption before you order. Drain choices are differential-pressure (default), automatic (this unit) or manual; automatic suits unattended installations. Filter grade is 40 um standard or 5 um (this unit, code W) for finer protection downstream. The embedded square gauge reads psi here; MPa and bar scales, and an external round gauge, are options. Thread is G on this unit; PT is the standard and NPT is an order option. A mounting bracket is included with the set.
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 we do not quote a number here. Send us your application details and we will confirm the flow curves and datasheet figures for the GC300 size before you order.
The standard element filters to 40 um, which suits general plant air. This unit carries the 5 um element (code W) for finer particulate removal ahead of sensitive valves, cylinders and tools. Both grades are catalogue options on GC units, and the automatic drain on this set removes collected condensate from the filter bowl without manual attention.
