The AirTAC AirTAC GC400C15AC2G F.R.L. Combination, G1/2, 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 GC series is AirTAC's three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one prep station. This GC400C15AC2G is the size 400 unit with a G1/2 (BSPP) port, an automatic drain on the filter bowl, the standard 40 um filter element, and an external round gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, maximum inlet pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). At this size the filter and lubricator bowls are polycarbonate, and a mounting bracket is included.
This is a genuine AirTAC part. The GC line spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual or differential-pressure drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads - PT is the standard, with G and NPT ordered as catalogue options. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures against 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: 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.

Delivers filtered, regulated and lubricated air to press cylinders and clamps fed from a 1/2 in main drop on a stamping or forming cell.
Supplies air cylinders, grippers and diverters on packaging lines where one F.R.L. station serves a whole machine section.
Point-of-use air prep for tools and actuators at shop stations, with the lubricator keeping tool seals oiled and the regulator holding set pressure.
Step up or down through sizes 200, 300, 400 and 600 to match the port and the flow your line needs; this size 400 unit carries a 1/2 in port. Choose the drain on the filter bowl: automatic (as coded here), manual, or the differential-pressure default. The 40 um element is standard and a 5 um element (code W) is available when finer filtration is wanted. Gauges can be ordered with MPa, psi or bar scales, and threads come as PT (standard), G or NPT. Brackets are included. Flow for this series is published as curves, not a single rated figure, so send us your application and we will confirm sizing from 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 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 there is no one l/min or SCFM number we can quote honestly. Tell us your application and we will confirm the sizing from the datasheet on request.
The trailing G specifies a G (BSPP) thread on the 1/2 in port; PT is the standard thread, and G or NPT are ordered as catalogue options. The C2 in the code selects the external round gauge with a psi scale; MPa and bar scales are available, and the embedded square gauge is the standard fitting.
