The AirTAC GC300C15AC2GK AirTAC F.R.L. Combination Unit 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, set up to clean water and particulate out of the compressed air, hold a steady downstream pressure and add a controlled oil mist for air tools and cylinders. This GC300C15AC2GK is built in size 300 with G1/2 ports, carries the standard 40 um filter element with an automatic drain on the filter bowl, and is fitted with the external round gauge reading in psi. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing). A reverse/check valve is fitted and the mounting bracket is included. At size 300, the filter and lubricator bowls are PC (polycarbonate).
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options, drain types, filter grades (40 um standard, 5 um with code W), gauge styles and scales, thread options and bracket choices to match. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures 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-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.

Feeding a mixed bank of impact wrenches, nut runners and air cylinders at a final-assembly station: the filter removes water and swarf carryover, the regulator holds a steady setting for consistent tool torque, and the lubricator keeps a light oil mist in the tool air lines.
Supplying the pneumatic pushers, clamps and sealing-head actuators along a packaging conveyor, where the automatic drain handles condensate between shifts and the check valve holds the set pressure against upstream dips.
A wall-mounted service drop for air drills, grinders and blow guns at a maintenance bench: one unit filters the shop air, sets the working pressure for the task at hand and meters oil mist into the stream to extend tool life.
Step through the real choices before ordering. Size and port: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air demand of the downstream circuit; this unit is size 300 with a 1/2 in port. Drain type: the filter bowl can be ordered with automatic drain (as here), manual drain, or the differential-pressure default, depending on how often the site can attend to draining. Filter grade: 40 um is the standard element; specify code W for the 5 um option where finer particulate removal is needed. Gauge: the embedded square gauge is standard and external round gauges are optional, with MPa, psi or bar scales - this configuration carries the round gauge in psi. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order, and this unit is specified with G. Bracket: included on this code. Because flow is published as curves and not a single rating, send us your application details and we will confirm sizing against the datasheet 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-C1 regulator with a GF300-C1 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Send us your application and required flow, and we will confirm the sizing against the datasheet on request before you order.
The A in the code sets an automatic drain on the filter bowl: collected condensate is discharged without anyone opening the drain by hand, which suits installations that run unattended or between shifts. Manual and differential-pressure drain versions are available on the same size if your site prefers them. Note also that this code carries the optional external round gauge reading in psi, the G (BSPP) thread, a fitted reverse/check valve and the included mounting bracket.
