The AirTAC GC400C15C2G AirTAC F.R.L. Combination G1/2 Round Gauge Psi 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 GC400C15C2G 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 size 400 unit is built for 1/2 inch ports with G (BSPP) thread, filters to 40 um as standard, and uses a differential-pressure drain on the filter bowl, so accumulated condensate bleeds off automatically when the pressure differential across the element rises. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), and this configuration is supplied with a round external gauge scaled in psi. No reverse/check valve is fitted, and a mounting bracket is included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600, with port options from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um (code W) filtration, gauge scale in MPa, psi or bar, and PT, G or NPT thread. Published flow data appears 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: 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.

At paint-line drop points the set filters water and particulate from the shop air, holds a steady regulated pressure at the spray guns, and meters oil mist to keep air tools and actuators running through the shift.
Feeding clamps, tool-change cylinders and chip-clearing blow-off on a machining centre, the combination cleans the compressed air, sets the working pressure the fixture circuit was designed around, and lubricates the valve-and-cylinder train.
On a filling and cartoning line the unit conditions the air serving grippers, diverters and case sealers: 40 um filtration ahead of the valves, regulated pressure for consistent actuator speed, and oil mist for the air cylinders.
Work from the port step first: size 400 carries 1/2 inch ports, and the GC range steps up through 200, 300, 400 and 600 as port size and flow demand grow - match the step against the flow your line needs, then let us confirm the curve. Choose the drain to suit the installation: differential-pressure (this unit) drains the filter bowl automatically as the element loads, automatic (code A) drains on a cycle, and manual (code M) needs an operator. Filtration is 40 um standard; specify 5 um (code W) where downstream valves or tools need finer air. The gauge here is a round external gauge in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is G (BSPP) on this code, with PT as the standard and NPT available to order, and a mounting bracket is included.
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 this series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line pressure and the flow your application needs, and we will confirm the datasheet curve and the right size step on request before you order.
The C2 code in GC400C15C2G specifies a round external gauge scaled in psi, which suits US-market panels. The catalogue also offers an embedded square gauge and MPa or bar scales, so you can order the same three-unit set with the gauge arrangement your panel reads.
