The AirTAC GC40010F2WGK 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and lubricator built up as one unit, so incoming compressed air is cleaned of water and particulate, regulated to your set pressure, and carries a fine oil mist to downstream components. This GC40010F2WGK is the size 400 unit with a G3/8 (BSPP) port, a 5 um filter element (code W), differential-pressure drain, standard regulator with an embedded square gauge reading in psi, and a reverse/check valve fitted; a mounting bracket is included. Max inlet pressure is 1.0 MPa (145 psi), the regulation range for this drain type is 0.15-0.9 MPa (20-130 psi), operating temperature is -5 to 70 C (non-freezing), and the filter and lubricator bowls are polycarbonate (only size 600 uses aluminium alloy).
It is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and with choices of drain type, 40 um standard or 5 um (W) filtration, gauge scale (MPa, psi or bar), thread (PT standard; G and NPT as order options) and check valve. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Feeding clamps, tool-change cylinders and air blow-off on a machining centre with filtered, regulated and lubricated air at a stable set pressure.
Conditioning the air supply to carton sealers, case packers and pick-and-place cylinders so seals and actuators run on clean, moisture-reduced, lubricated air.
Installed at the air drop feeding a work cell of air tools and pneumatic screwdrivers, combining filtration, regulation and oil-mist lubrication in one unit.
The real choices within the GC line: step through sizes 200/300/400/600 and ports 1/8 to 1 inch against the flow your line needs; pick the drain (differential-pressure as here, automatic, or manual); choose 40 um standard or 5 um (W) filtration; set the gauge scale to MPa, psi or bar; and order PT (standard), G or NPT thread. This unit already carries the 5 um element, the psi square gauge and the check valve, so it suits applications that need finer filtration and protection against reverse flow. Regulation range is 0.15-0.9 MPa (20-130 psi) with this drain type, against a 1.0 MPa (145 psi) maximum inlet.
Because rated flow is published only as curves, not a single figure, 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 GC series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing against the datasheet curves on request before you order.
Yes. The GC series is standard with a 40 um element; the W code on GC40010F2WGK specifies the finer 5 um grade, which suits applications with sensitive downstream components. This unit also carries a differential-pressure drain, a square psi gauge and a reverse/check valve (code K); if you would rather have 40 um filtration, a different drain or gauge scale, ask us for the equivalent code.
