The AirTAC GC40010ALF2WGK 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 GC series is a three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one set, so one connection conditions compressed air for filtration (water and particulate removal), regulation and lubrication in a single installation. This configuration, GC40010ALF2WGK, is the size 400 unit with a G3/8 (BSPP) port. The filter element is the fine 5 um grade (code W) and the filter bowl has an automatic drain, so collected condensate is expelled without manual attention. The regulator is the low-pressure type and carries the embedded square gauge with a psi scale; a reverse/check valve is fitted and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). The bowls on size 400 units are PC (polycarbonate); only size 600 uses aluminium alloy.
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with matching ports, a choice of drain types (differential-pressure, automatic or manual), 40 um standard or 5 um fine filtration, gauge scales in MPa, psi or bar, and PT (standard), G or NPT thread options. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures for your application before ordering.

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.

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 spray guns and air-assisted applicators on a paint line, where the 5 um element protects the finish from particulate carryover, the regulator holds a steady low-pressure setting and the lubricator mists the gun's air motor.
Installed upstream of a machining centre's clamps, tool-change cylinders and air blow-off circuits, conditioning the supply so clamping pressure stays regulated and moving seals receive oil mist.
Mounted at the drop feeding a packaging line's conveyor diverters, box-forming cylinders and label-head actuators, where filtered, regulated and lubricated air keeps the line's pneumatic motion consistent shift after shift.
Start with size and port: the GC series steps through sizes 200, 300, 400 and 600, and the two digits after the size set the port (06 to 1/8", 08 to 1/4", 10 to 3/8", 15 to 1/2", 20 to 3/4", 25 to 1"). Match the size step to the air demand of the downstream equipment. Then pick the drain: differential-pressure (default), automatic for unattended condensate removal, or manual where you prefer operator control. Choose the filter grade - 40 um standard or 5 um (code W) for finer protection of valves and cylinders. Set the gauge scale to MPa, psi or bar, and select the thread: PT is the standard, with G (BSPP) and NPT available as order options. A mounting bracket is included on this unit. One honest note on sizing: flow for this series is published as curves, not a single rated number, so ask us to confirm sizing against your application and the datasheet 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 series as curves, not as a single rated figure, so we do not quote a rated flow number. Tell us your application and required air demand and we will confirm the sizing against the datasheet on request before you order.
W is the filter grade: 5 um fine filtration instead of the 40 um standard element. K means a reverse/check valve is fitted. A is the automatic drain on the filter bowl, which expels collected condensate by itself instead of the differential-pressure default, so no manual draining is needed.
