The AirTAC GC40015AF2WGK AirTAC F.R.L. Combination G1/2, 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning station. This 400-size unit is set up with a G1/2 port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain on the filter bowl, a square pressure gauge reading in psi, a reverse/check valve on the regulator, and a mounting bracket. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, with a maximum inlet pressure of 1.0 MPa (145 psi) and a regulator adjustment range of 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 40 um standard element, gauge scale in MPa or bar, and PT or NPT threads in place of G. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for 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: GF400-15 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 clean, regulated and lubricated air to the tool-change cylinders, clamps and pneumatic actuators on a machining centre, with the 5 um element protecting fine control valves from particulate carryover.
A conditioning point on the air drop serving robotic grippers and pick-and-place cylinders, where the regulator holds a stable working pressure and the lubricator carries oil mist to the actuators.
Supplies treated air to the sealing jaws, diverters and conveyor stop cylinders on a packaging line, with the automatic drain removing condensate so the line keeps running without daily bowl checks.
Size and port are the first decision: the 400 size with its 1/2 in port sits in the middle of the GC range (200/300/400/600), and the right step depends on the air demand of the downstream circuit - we can check the published flow curves against your requirement. This unit already carries the finer 5 um element (W code) instead of the 40 um standard, an automatic drain (no manual draining of condensate), a square psi gauge, and a reverse/check valve. If you would prefer a manual or differential-pressure drain, a 40 um element, an MPa or bar gauge scale, a PT or NPT thread, or a different size, those are catalogue options on the same family. Because flow is published 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 we do not quote a rated flow, Cv or SCFM number. Tell us your working pressure and the air demand of your circuit and we will confirm the flow figures from the datasheet for this 400-size, G1/2 unit before you order.
The A in the code specifies an automatic drain, which ejects collected condensate from the filter bowl without manual attention - useful on lines that run unattended. The W code specifies the 5 um element instead of the 40 um standard, the finer filtration choice for protecting downstream valves and cylinders. Both are catalogue options on the GC family if you need a different combination.
