The AirTAC GC40010AF2WG AirTAC F.R.L. Combination 3/8 in G Thread 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 GC40010AF2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is the size 400 unit with a 3/8 in port in G (BSPP) thread, a 5 um filter element for finer particulate removal, an automatic drain that expels collected condensate without manual attention, and a fitted square gauge reading in psi. The standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), the polycarbonate bowls suit -5 to 70 C non-freezing service, and a mounting bracket is included.
This is a genuine AirTAC part. The GC range spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options include manual or differential-pressure drains, the 40 um standard element, alternative gauge scales (MPa, psi, bar), PT or NPT thread, and a reverse/check valve. Flow is published 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.

Feeding filtered, regulated and lubricated air to the pneumatic actuators, clamps and tool-changer cylinders on a machining centre, with the 5 um element protecting fine control valves.
Conditioning air for the pick-and-place and sealing cylinders on a packaging conveyor, where the automatic drain handles condensate during continuous shifts and the lubricator mists oil to the cylinders.
Serving as the point-of-use F.R.L. at a drop from the plant air ring main, giving each assembly cell its own filtration, set pressure and oil mist for air tools and screwdrivers.
Size 400 with a 3/8 in port sits in the middle of the GC range; step up to 600 or down to 300/200 according to the flow your line needs, and confirm the match against the published flow curves before ordering. Drain choice matters: automatic (this unit) suits unattended duty, manual drain suits supervised points, and the differential-pressure default drains on a pressure drop. Filter grade is 5 um here (code W) against the 40 um standard - choose 5 um where downstream valves and cylinders need finer protection. The fitted square gauge reads psi; MPa and bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this model, with PT as the standard and NPT as an order option. Flow is published as curves, not a single rating, so send us your application details and we will confirm sizing 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 the GC400 as curves rather than a single rated figure, so there is no one rated flow number we can quote. Tell us your working pressure and the air demand of the equipment you are feeding, and we will confirm the sizing from the datasheet on request before you order.
The W code in GC40010AF2WG specifies the 5 um element instead of the 40 um standard, giving finer particulate removal for sensitive downstream valves and cylinders. The A code specifies the automatic drain, which expels collected condensate on its own - a good fit where the unit runs unattended; manual and differential-pressure drains remain available in the range.
