The AirTAC GC40010AC2GK AirTAC 3-Piece F.R.L., G3/8 (3/8 in) 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 40 µm element, a automatic 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 assembled as one unit. This GC40010AC2GK is built for G3/8 (3/8 in) lines and carries an automatic drain on the filter bowl, the standard 40 um filter element, a standard-type regulator, a round gauge reading in psi, a reverse/check valve and a mounting bracket. The bowls on the 400 size are polycarbonate (PC).
It is a genuine AirTAC part, rated for compressed air at up to 1.0 MPa (145 psi) inlet, with a regulation range of 0.15-0.9 MPa (20-130 psi) and a working temperature of -5 to 70 C (non-freezing). The GC line is available in sizes 200, 300, 400 and 600 with PT, G or NPT threads, a choice of drain type, 40 um or 5 um (W) filtration and gauge scale options. Flow is published as curves rather than a single rating, so we confirm figures from the datasheet 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: GF400-10 filter, GR400-10 regulator and GL400-10 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.

Feeds filtered, regulated and lubricated air to the clamping fixtures, tool-change cylinders and air gates on a CNC machining centre, with the psi round gauge giving the operator a direct setpoint readout at the machine.
Conditions the air feeding carton-forming and case-sealing cylinders on a packaging conveyor line; the 40 um element removes water and particulate while the lubricator keeps cylinder and valve seals running smoothly.
Supplies a spray booth or paint shop ring main, where the regulator holds a steady gun pressure, the filter drops water and grit before the guns, and the oil mist protects downstream air tools.
Size and port are the first choice: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air demand of the circuit - this unit sits at 400 with a 3/8 in G thread. Where a bowl is fitted you can choose differential-pressure drain (the default), automatic drain (this model) or manual drain; the regulation range follows that choice - 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, 0.05-0.9 MPa (7-130 psi) with manual drain. Filter grade is 40 um standard or 5 um with code W. Gauges come as an embedded square gauge or an external round gauge with MPa, psi or bar scales. Thread is PT as standard with G and NPT as order options, and a bracket is included on this model. 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the flow from the GC400 datasheet on request before you order.
The A in GC40010AC2GK sets an automatic drain, which discharges collected condensate without manual intervention. The GC series is also offered with differential-pressure drain (the default) or manual drain (code M). Note the regulation range differs: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with manual drain.
