The AirTAC GC40010ALC2WGK AirTAC F.R.L. Combination, G3/8 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 PT3/8" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40010ALC2WGK is a three-piece F.R.L. combination: a filter, a pressure regulator and a lubricator assembled as one air-treatment set for compressed air. This size 400 configuration is specified with G3/8 ports, a 5 um filter element (the finer of the two catalogue grades), an automatic drain on the filter bowl, a low-pressure regulator type, a round pressure gauge reading in psi, a reverse/check valve, and a mounting bracket. It conditions air in one pass: water and particulate are drained off, downstream pressure is set on the regulator, and oil mist is metered to lubricate downstream air tools and actuators.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port options, drain types, filter grades, gauge styles and scales to suit the application. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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. 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.

|---|---|
| 10 | Port size PT3/8". 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. |

| 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: GF400-10 filter, GR400-10 regulator and GL400-10 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 clamp cylinders and tool-change actuators on a machining centre, with the 5 um element protecting close-tolerance valve spools and the psi gauge letting setters verify clamp pressure at the cell.
Supplies treated air to the grippers, wrap arms and sealing cylinders on a bottling or packaging line, where the automatic drain keeps condensate out of the circuit during washdown-heavy shifts and the lubricator oils the cylinders in continuous duty.
Mounted at the drop for impact wrenches, ratchets and air screwdrivers in a body or assembly shop, metering oil mist to the tools, holding a stable set pressure via the regulator, and using the check valve to keep the circuit from dumping on supply loss.
Size 400 with G3/8 ports sits in the middle of the GC range; step up to size 600 or down to 300/200 if your line's flow demand points elsewhere - we can check the published flow curves against your consumption before you order. The 5 um element (code W) suits applications that need finer particulate removal than the 40 um standard; the automatic drain empties the bowl without manual attention, which matters where the unit is mounted in a hard-to-reach spot. The gauge here is the external round type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is specified as G (BSPP) on this unit - PT is the standard thread and G/NPT are order options. A bracket is included, and the reverse/check valve holds downstream settings if upstream supply is interrupted.
Note that this is the low-pressure regulator type; the exact adjustment range for the low-pressure variant is not published in the sheet we work from, so confirm your set pressure with us before ordering. Flow is published as curves, not a single rating - ask us to confirm sizing against the 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for this family as curves, not as a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your application's flow demand and line pressure and we will confirm the figures from the datasheet on request before you order.
The code decodes it that way: A is the automatic drain (instead of the differential-pressure default or a manual drain), and W is the 5 um filter grade instead of the 40 um standard. The automatic drain removes condensate without operator attention, and the 5 um element gives finer particulate removal. If you would rather have the 40 um element or a different drain type, that is a catalogue option - just tell us which configuration you need.
