The AirTAC GC40015AF2WK AirTAC F.R.L. Combination, PT1/2 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AF2WK is an AirTAC GC series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built on the size 400 body with PT1/2 ports, carries a 5 um filter element (code W) with an automatic drain on the filter bowl, and includes a check (reverse) valve so downstream settings and lubrication are held if upstream supply is interrupted. The regulator is the standard type with an embedded square gauge scaled in psi, and a mounting bracket is included for panel or frame fixing.
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with matching port sizes, and can be ordered with manual or differential-pressure drains, a 40 um standard element instead of 5 um, alternative gauge scales (MPa, psi or bar), G (BSPP) or NPT threads, and with or without a check valve. Flow is published by AirTAC as curves rather than a single rated figure, so we confirm the datasheet and sizing 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: GF400-15 filter, GR400-15 regulator and GL400-15 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.

Feeds filtered, regulated and lubricated air to the tool-change actuators and pneumatic clamps on a machining centre, with the 5 um element protecting fine-tolerance valves from particulate carryover.
Conditions the air feeding spray guns and transfer pumps on a paint line, where stable regulated pressure and consistent oil misting keep finish quality uniform across the shift.
Supplies the cylinders and grippers on a carton-forming and sealing conveyor, with the automatic drain removing condensate from compresses air before it reaches the valves.
Step up or down through the GC sizes (200/300/400/600) to match the port size and flow demand of the air system; this size 400 unit carries 1/2 in PT threads. Choose the drain to suit access: automatic (this model) for unattended condensate removal, manual where an operator drains on schedule, or the differential-pressure default. Filter grade is 40 um standard or 5 um (W) where finer particulate protection is needed - this unit is the 5 um option. Gauge scale can be MPa, psi (this model) or bar, with an external round gauge available as an alternative to the embedded square gauge. Thread is PT as standard; G (BSPP) and NPT are orderable options, and a check valve (K, fitted here) and mounting bracket are selectable.
Because AirTAC publishes flow as curves rather than a single rating, ask us to confirm sizing against your 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no one number is quoted here. Tell us your application and we will confirm the flow and datasheet figures for this size 400 unit on request.
The A in the code sets an automatic drain on the filter bowl, so condensate is ejected without operator attention - useful where the unit sits in an inaccessible spot. The K fits a reverse (check) valve, which holds the regulated downstream pressure and lubrication if the upstream supply is cut. Both are optional; the defaults are a differential-pressure drain and no check valve.
