The AirTAC GC300C08AC2WG 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-unit F.R.L. combination: a filter, a pressure regulator and an oil-mist lubricator supplied as separate matched units, so one installation cleans, regulates and lubricates the compressed air. This size 300 set is configured for G1/4 (BSPP) ports, with a 5 um filter element (the standard element is 40 um; the W code orders the finer grade), an automatic drain on the filter bowl, a standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range, and an external round pressure gauge reading in psi. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. On this 300 size the filter bowl is polycarbonate (only the 600 size uses aluminium alloy), and a mounting bracket is included.
This is a genuine AirTAC part. The GC range is available in sizes 200, 300, 400 and 600 (a larger size means a larger port and more flow), with manual, automatic or differential-pressure drains, 40 um or 5 um (W) filtration, embedded square or external round gauges scaled in MPa, psi or bar, and PT (the standard thread), G or NPT as order options. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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-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 clean, regulated and lubricated air to the pneumatic clamps and tool-change cylinders of a machining centre, with the 5 um element protecting fine spool valves upstream of the cell.
Supplying carton-forming, sealing and case-packing cylinders on a packaging line, where the automatic drain handles condensate through multi-shift running and the lubricator keeps cylinder seals working.
Air preparation for impact wrenches, air screwdrivers and riveters at an automotive or furniture assembly station, with the regulator holding a steady setting for consistent tool torque.
The primary choice is size and port: the 200/300/400/600 steps move up in port size and flow capacity, so match the set to the air demand of the circuit - this is the 300 size with G1/4 ports. Drain type matters at the filter: automatic drains condensate without attention, manual requires periodic bleeding, and the differential-pressure default drains on a pressure drop; this set carries the automatic drain. Filter grade is 5 um here (W code) against the 40 um standard - choose the finer grade where downstream valves and cylinders need cleaner air. The gauge on this set is an external round type reading psi; embedded square gauges and MPa or bar scales are the alternatives. Threads come as PT (standard) with G or NPT to order, and a bracket is included. Flow is published as curves, not a single rating, so 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 there is no one l/min or SCFM number we can quote honestly. Tell us your line pressure and the air demand of your equipment, and we will confirm the correct size and the datasheet flow curve for this G1/4 set on request before you order.
The A code in GC300C08AC2WG means the filter bowl carries an automatic drain, which expels collected condensate without anyone opening the bowl - useful on unattended or multi-shift lines. The alternatives are manual draining (M code), which needs periodic bleeding by an operator, and the differential-pressure drain, which is the series default and drains on a pressure drop across the element.
