The AirTAC GC40015ALF2WGK AirTAC F.R.L. Combination Unit, 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 GC40015ALF2WGK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is built on the GC400 size with G1/2 ports, carries a 5 um filter element (the finer of the two published grades), and uses an automatic drain so collected water is expelled from the filter bowl without manual attention. The regulator is the low-pressure type and is fitted with an embedded square gauge reading in psi; a reverse/check valve is fitted, and a mounting bracket is included. The filter and lubricator bowls are polycarbonate (PC).
This is a genuine AirTAC part. The GC series is published in 200, 300, 400 and 600 sizes with a choice of ports, threads (PT standard; G and NPT as order options), drain types, filter grades, gauge styles and scales. 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. 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.
| GC400 | G-series F.R.L. combination, 400 body — sets the port range. |
|---|---|
| 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). |
| F | Gauge shape: Square. 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.

Feeding pneumatic clamps, tool-change cylinders and chip-clearing jets on a machining centre, where the 5 um element protects precision valves and the lubricator mists oil to the actuators.
Conditioning shop air ahead of spray guns and air-assisted applicators, where water and particulate must be stripped out, pressure held steady at low settings, and a fine mist carried to the gun.
Supplying the diverters, pushers and sealing cylinders along a packaging line, with automatic drainage handling condensate through continuous shifts and the psi gauge giving operators a local setpoint readout.
Start with the port step: the GC series steps through 200, 300, 400 and 600 sizes, and the 400 size with its 1/2 in port sits in the middle of that range, so size up or down against the air demand of the machine it feeds. Choose the drain to match access: automatic (this unit) for unattended duty, manual for periodic checks, or the differential-pressure default. Filter grade is a real choice: 40 um is standard and 5 um (code W, as here) suits finer protection downstream. Gauge scale is selectable (MPa, psi or bar) and the embedded square gauge is standard with an external round gauge optional. Thread is PT as standard with G and NPT available as order options, and a bracket is included on this unit. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application 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 GR400-15 regulator with a GF400-15 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 application and we will confirm the flow and datasheet figures for this unit on request before you order.
This configuration is the low-pressure type of regulator, and the exact adjustment range for that type is not published in the catalogue sheet we work from. We will confirm the range on request. The unit otherwise carries the standard GC400 specification: 1.0 MPa (145 psi) maximum inlet pressure, -5 to 70 C operation, and an embedded square gauge reading in psi.
