The AirTAC GC40015AC2WG 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 GC40015AC2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 3-piece set. This configuration is the size 400 unit with a G1/2 (BSPP) port, automatic drain on the filter bowl, a fine 5 um filter element, a standard regulator with a round psi gauge fitted, and the mounting bracket included. In use, it cleans water and particulate from the compressed air, holds a set downstream pressure, and adds oil mist for downstream air tools and cylinders.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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.

|---|---|
| 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)). |
| (blank) | Standard 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. |

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 cleaned, regulated and lubricated air to pallet clamps, tool-changer cylinders and air-powered fixtures on a machining centre, with the 5 um element protecting fine pilot valves.
Supplying the pick-and-place cylinders, baggers and carton sealers on a packaging conveyor, where the automatic drain keeps condensate off the valves during continuous shifts.
A point-of-use three-piece set at an assembly station running air screwdrivers and pneumatic press cylinders, with the lubricator extending tool life and the regulator holding set pressure.
Size 400 with a 1/2 in port sits in the middle of the GC range: step up to 600 or down to 300/200 depending on the flow your line needs at that port. The automatic drain on this unit handles condensate without daily manual attention; manual and differential-pressure drains are the other catalogue choices. The 5 um element (code W) suits applications more sensitive to particulate than the 40 um standard element. The fitted round gauge reads in psi; embedded square gauges and MPa/bar scales are the alternatives. Thread here is G (BSPP); PT is the standard thread and G/NPT are order options. Bracket is included.
Because flow is published as curves and not 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 this series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Send us your application details and we will confirm the flow and sizing figures from the datasheet on request.
The A in the code means the filter bowl drains condensate automatically instead of relying on someone opening a manual drain or on a differential-pressure trigger. It suits units mounted in less accessible positions or on lines running unattended; manual and differential-pressure drains remain catalogue options if you prefer them.
