The AirTAC GC400C15AF2WK AirTAC F.R.L. Combination, PT1/2, 5 um 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 AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-preparation set. This GC400C15AF2WK is the size 400 unit with a PT1/2 port, so it conditions the air supply for a 1/2 in line: the filter element removes water and particulate down to 5 um, the automatic drain ejects collected condensate from the bowl without manual attention, the regulator holds downstream pressure anywhere in its 0.15-0.9 MPa (20-130 psi) adjustment range, and the lubricator meters oil mist into the air for downstream tools and cylinders. The embedded square gauge reads in psi, a reverse/check valve is fitted, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with a matching port step, and with options for drain type, 40 um or 5 um filtration, gauge scale (MPa, psi or bar), reverse/check valve and G or NPT thread in place of the PT standard. Flow is published as curves rather than a single rating, so ask us and we will confirm the sizing and datasheet figures for your application before you order.

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 booths and air-driven paint equipment where the 5 um element protects the finishing process from water and particulate while the regulator holds a steady gun pressure and the lubricator is set to serve air tools on the line.
Conditioning the plant air feeding carton sealers, wrappers and palletiser cylinders: clean, regulated and lubricated air keeps actuators and valves running consistently through long production shifts.
Supplying CNC workholding clamps and air-powered fixtures where stable regulated pressure is needed for repeatable clamping force, the check valve holds the circuit against supply dips, and the automatic drain keeps condensate out of the clamping lines.
Start with the port step: size 400 carries a 1/2 in port, and the GC range steps through 200, 300, 400 and 600, so pick the size whose flow curve covers your line demand rather than matching port thread alone. Choose the drain to suit access: automatic (this unit) drains the bowl on its own, manual needs an operator, and the differential-pressure default drains on a pressure drop. Choose 40 um for general air preparation or 5 um (code W, as here) where finer particulate removal matters. The gauge is the embedded square type; scale can be MPa, psi or bar, and an external round gauge is optional. Thread is PT as standard, with G (BSPP) and NPT as order options; a reverse/check valve and mounting bracket can be specified. Flow is published as curves, not a single rated figure, so send us your application and we will confirm sizing against 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, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your line size and air demand and we will confirm the sizing against the datasheet curves on request before you order.
The A in the code GC400C15AF2WK specifies an automatic drain, which ejects collected condensate from the filter bowl without operator attention - useful where the unit is mounted in an inaccessible spot. The GC series can also be ordered with a manual drain or with the differential-pressure drain as the default, and the filter grade can be the 40 um standard or this 5 um (W) option.
