The AirTAC GC40015ALC2WGK 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 PT1/2" ports, a 5 µm element, a automatic 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, pressure regulator and lubricator set up together as one complete air-preparation station. This GC40015ALC2WGK is the size 400 unit with a G1/2 port, automatic drain, 5 um filtration (the W grade), a low-pressure type regulator, a round gauge scaled in psi, a reverse/check valve and a mounting bracket. The filter and lubricator bowls are polycarbonate; maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and options for drain type, 40 um or 5 um filtration, gauge style and scale, PT, G or NPT thread, and a reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm the 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

|---|---|
| 15 | Port size PT1/2". This body offers 10 = PT3/8", 15 = PT1/2". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| W | Filtering grade 5 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| G | G (BSPP) thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Supplies filtered, regulated and lubricated air to spray guns and air-assisted equipment. The 5 um grade supports finish quality, the automatic drain handles condensate without daily attention, and the psi gauge lets the booth operator verify setpoints at a glance.
Prepares air for clamping fixtures, tool-change cylinders and air-blast nozzles. The low-pressure type regulator suits circuits that run below full line pressure, while the reverse/check valve guards downstream circuits against backflow if supply pressure drops.
Feeds the cylinders and air actuators on filling, capping and carton-sealing stations. The lubricator delivers an oil mist to keep actuators running smoothly, the filter removes water and particulate before it reaches the valves, and the automatic drain suits lines that run unattended.
Size and port set the air capacity: step up from 200 to 600 as your flow demand grows, with this size 400 unit carrying a 1/2 inch port. Choose the drain to match the installation: automatic (fitted here) where the unit is hard to reach, manual for periodic servicing, or the differential-pressure default. Filtration is 5 um on this unit (W code) against the 40 um standard, and the regulator is the low-pressure type for circuits that run below full line pressure. The gauge is round and scaled in psi, with MPa and bar scales available as alternatives, and the thread is G (BSPP) where PT is the standard and NPT is an order option. Flow is published as curves, not a single rating, so 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 number here. Tell us your application and we will confirm the flow and the full datasheet figures for this GC40015ALC2WGK on request.
This unit carries the A code, so the filter bowl expels collected condensate automatically without daily manual attention. The GC range is also available with a manual drain or the differential-pressure default if your maintenance routine prefers one of those.
