The AirTAC GC30010C2WK AirTAC F.R.L. Combination, PT3/8 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 PT3/8" ports, a 5 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, pressure regulator and lubricator assembled into one conditioning station. This GC30010C2WK is built for 3/8 in PT lines and pairs a 5 um filter element (the finer of the two published grades) with a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi), a differential-pressure drain, a round pressure gauge reading in psi, and a reverse/check valve. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls are polycarbonate at this size, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options including manual or automatic drains, the 40 um standard element, G (BSPP) or NPT threads, and gauge scales in MPa, psi or bar. Rated flow is published as curves rather than a single figure, so ask us to confirm sizing and datasheet details 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: GF300-10 filter, GR300-10 regulator and GL300-10 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.

Conditioning the shop-air feed to pneumatic vises, clamps and tool-change cylinders on a machining centre: water and particles down to 5 um removed, pressure held steady by the regulator, and oil mist delivered to the actuators.
Feeding the pick-and-place and sealing cylinders on a packaging conveyor, where the regulator keeps actuation pressure consistent across the shift and the lubricator protects cylinders and directional valves.
Prepping air for spray guns and air motors in a finishing shop: the 5 um grade helps protect the finish from water and particulate while the regulator sets gun pressure at the point of use.
Choose the size by the port and flow step: size 300 sits at 3/8 in PT here, with 200/300/400/600 covering 1/8 in to 1 in as demand grows. Drain options are differential-pressure (this unit), automatic (A) or manual (M), and the filter element is 5 um (W) versus the 40 um standard. The gauge can be the embedded square type or an external round gauge scaled in MPa, psi or bar - this code specifies a round psi gauge - and K adds a reverse/check valve. Threads come as PT standard, with G (BSPP) or NPT as order options. Because rated flow is published as curves rather than one number, send us your flow and pressure requirements and we will confirm the right size 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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote one number. Send us your line pressure and required flow and we will confirm sizing against the published curves and datasheet on request.
The W in the code specifies the optional 5 um element instead of the 40 um standard, and C2 specifies the external round gauge with a psi scale (1 = MPa, 2 = psi, 3 = bar). The K adds a reverse/check valve. All are catalogue options you can order in other combinations.
