The AirTAC GC400C15C2 AirTAC F.R.L. Combination PT1/2 Round psi Gauge 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 GC400C15C2 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is size 400 with PT1/2 (1/2 in) ports, a 40 um standard filter element, a differential-pressure drain on the filter bowl, and a standard regulator adjustable from 0.15 to 0.9 MPa (20-130 psi). An external round gauge with a psi scale is fitted, the mounting bracket is included, and no reverse/check valve is fitted. The filter and lubricator bowls on this size are polycarbonate.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread type and bracket. Rated flow for this series is published as curves rather than a single 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: GF400-C1 filter, GR400-C1 regulator and GL400-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.

A size 400, 1/2 in F.R.L. set feeding clamps, tool-change cylinders and pallet-actuation circuits on a CNC machining cell: the filter removes water and particulate, the regulator holds the clamp pressure steady, and the lubricator mists oil to the valve and cylinder seals.
Point-of-use air preparation at paint-line drops and air-tool stations in an automotive assembly plant, where the 40 um element and differential-pressure drain keep moisture and debris out of spray equipment and the lubricator conditions the air tools in daily use.
Supplying diverters, case packers, grippers and palletiser cylinders on a packaging line, where a single 1/2 in F.R.L. set conditions the whole drop: clean, regulated, lubricated air for high-cycle actuators, with the round psi gauge giving operators a local pressure reference.
Start with the size and port step: 200, 300, 400 and 600 correspond to increasing port sizes (here PT1/2) and increasing flow capacity, so size the unit against the air demand of the circuit rather than the pipe alone. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against the datasheet before ordering. Then set the real decodable choices: drain type on the filter (differential-pressure as here, automatic with code A, or manual with code M); filter grade (40 um standard as here, or 5 um with code W for finer particulate); gauge style and scale (embedded square gauge standard, external round gauge optional, scales MPa, psi or bar - this unit carries a round psi gauge); thread (PT is the standard, with G/BSPP and NPT available as order options); and bracket (included here, omitted with code J). The regulator on this unit is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range under differential-pressure drain.
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-C1 regulator with a GF400-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 rated flow, Cv or SCFM number. Tell us your application and required flow, and we will confirm the datasheet figures for the GC400 size on request before you order.
In the GC code, the gauge position carries the gauge style and scale: C means an external round gauge and 2 means a psi scale, so GC400C15C2 is fitted with a round gauge reading in psi (an embedded square gauge is the standard alternative, with MPa or bar scales also available). The drain position is blank, which is the differential-pressure drain on the filter bowl; automatic drain is code A and manual drain is code M.
