The AirTAC GC400C15ALC2WGK AirTAC F.R.L. Combination G1/2 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 GC400C15ALC2WGK is a three-piece AirTAC GC combination that filters, regulates and lubricates compressed air using three separate units: a filter, a regulator and a lubricator. This size 400 configuration is built with G1/2 (BSPP) ports, a 5 um filter element for finer water and particulate removal, an automatic drain that expels collected condensate without manual attention, and a low-pressure regulator supplied with a round psi gauge. A reverse/check valve is fitted and a mounting bracket is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowls are metal.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and with choices of drain type, filter grade, gauge style and scale, thread (PT standard, G and NPT to order) and reverse/check valve. Flow for this series is published as curves rather than a single rating, so ask us to confirm sizing and any datasheet figure against your application before ordering.

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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element, low-pressure regulation and oil misting help protect finish quality.
Supplying actuators and valves on carton formers, sealers and case packers, with the automatic drain keeping condensate out of the circuit during long runs.
Powering workholding clamps and tool-change cylinders on machining centres, where filtered, regulated and lubricated air keeps actuation consistent shift after shift.
The real choices in this series are all decodable from the model code. Step through sizes 200/300/400/600 and the matching port (here G1/2) according to the flow your line needs. Choose the drain: differential-pressure (the default), automatic (as fitted here) or manual. Choose the filter grade: 40 um standard or 5 um with the W code (fitted here). Regulators come in standard or low-pressure type; this unit is the low-pressure type, and its exact regulation range is not published, so confirm it with us. Gauges: an embedded square gauge is standard and an external round gauge is optional, with MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard with G (BSPP) and NPT as order options, and a mounting bracket is included on this configuration. Because flow is published as curves rather than a single rating, ask us to confirm sizing against the 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number here. Tell us your line demand and we will confirm sizing from the datasheet on request.
The A in the code fits the automatic drain, which expels collected condensate without manual attention. The series is also offered with a manual drain, while the differential-pressure drain is the default - tell us which you prefer when ordering.
