The AirTAC GC40010AC2WG 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 GC40010AC2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is the GC400 size with a G3/8 port, fitted with the 5 um filter element (code W) for finer water and particulate removal than the 40 um standard element, an automatic drain that expels collected condensate without manual attention, a standard regulator covering 0.15-0.9 MPa (20-130 psi), and a round pressure gauge reading in psi. The bowls on the 400 size are polycarbonate (PC), and the set carries a maximum inlet pressure of 1.0 MPa (145 psi) with an operating temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with a choice of ports, drain types (differential-pressure, automatic or manual), filter grades (40 um standard, 5 um optional), gauge styles and scales, and PT, G or NPT threads. Flow is published in the catalogue as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. 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: GF400-10 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 pneumatic clamps, tool-change actuators and chip ejection cylinders on a machining centre, with the 5 um element protecting fine valves from particulate carryover.
Prepares air for spray guns and atomising stations on a paint booth line: water and 5 um particulate removal ahead of the gun, a steady regulated pressure at the booth, and oil mist for air-tool circuits elsewhere on the line.
Supplies the vacuum generators, sealing jaws and case-eject cylinders on a cartoning line, keeping condensate out of the valves with the automatic drain while the regulator holds a consistent setting across shifts.
Size and port set the capacity of the unit: the GC400 with its 3/8 in port sits mid-range in the GC line (200/300/400/600), so step up or down a size if your line flow sits near the edge of the curve. Choose the drain to match site practice: automatic (this unit) drains condensate unattended, manual needs an operator, and the differential-pressure default drains on a pressure drop. This unit carries the 5 um element (W); the 40 um standard element suits general lines where finer filtration is not required.
Gauge style and scale are decodable choices: embedded square gauge is standard, an external round gauge is optional, with MPa, psi or bar scales - this code specifies a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT available as order options; this unit is the G-thread version. 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 GR400-10 regulator with a GF400-10 filter on that branch.
AirTAC publishes flow for the GC400 as curves in the catalogue rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your line flow and pressure and we will confirm the datasheet curve and sizing for your application on request before you order.
The W in the code specifies the optional 5 um element instead of the 40 um standard, giving finer particulate removal for sensitive downstream equipment. The A specifies an automatic drain, which expels collected condensate from the filter bowl on its own instead of waiting for a manual drain - useful on lines that run unattended.
