The AirTAC GC300C15AC2G AirTAC F.R.L. Combination G1/2 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 GC300C15AC2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled for 1/2 in (G1/2) porting with G thread. This configuration carries an automatic drain on the filter bowl, the standard 40 um filter element, a fitted round gauge reading in psi, and the standard regulator with a 0.15-0.9 MPa (20-130 psi) adjustment range. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. The 300-size bowls are polycarbonate, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um (W) filtration, gauge style and scale, PT, G or NPT thread, and a reverse/check valve option. Flow is published as curves rather than a single rating, 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-C1 filter, GR300-C1 regulator and GL300-C1 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.

Supplies filtered, regulated and lubricated air to clamps, tool changers and cylinders on a CNC machining cell, with the 40 um element catching water and pipe-scale particulate before the regulator is set to the machine's working pressure.
Feeds the stopper cylinders and diverters along a bottling plant conveyor, where the lubricator maintains an oil mist for cylinder seals and the automatic drain empties the filter bowl without stopping the line.
A three-unit point-of-use supply for air tools and fixtures at an automotive assembly station, with the round psi gauge giving operators a local pressure readout at the workplace.
Size and port step up with air demand: 200, 300, 400 and 600 cover ports from 1/8 in to 1 in, and this unit sits at 300 with a 1/2 in G1/2 port. The filter drain is differential-pressure by default, with automatic (this unit) or manual as options; the regulator adjustment range follows the drain type, so an automatic-drain filter gives 0.15-0.9 MPa (20-130 psi). Filtration is 40 um standard or 5 um with the W code. Gauges are an embedded square gauge as standard or an external round gauge, scaled in MPa, psi or bar (this unit: round, psi). Thread is PT as standard with G and NPT as order 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-C1 regulator with a GF300-C1 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 operating pressure and air demand and we will confirm the flow from the datasheet for this 300-size, G1/2 unit before you order.
A GC combines a separate filter, regulator and lubricator, so each element can be serviced or replaced on its own; a GFC packages the filter-regulator and lubricator as a two-piece set. This GC300C15AC2G adds an automatic-drain filter bowl, a 40 um element and a round psi gauge, and a 5 um element is available with the W code.
