The AirTAC GC400-10 AirTAC F.R.L. Combination, PT3/8, 5 um 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 GC400-10 is a three-piece AirTAC F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit for compressed air. This configuration is built for a PT 3/8 inch port in size 400, with a 5 um filter element (the finer of the two published grades), an automatic drain on the filter bowl so collected condensate is expelled without manual attention, and a round pressure gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi). The filter and lubricator bowls are polycarbonate (only size 600 uses aluminium alloy), no reverse/check valve is fitted, and the set includes a mounting bracket.
This is a genuine AirTAC part. The GC line is published in sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, and choices of drain type, filter grade, gauge style and scale, and thread (PT standard, with G and NPT as order options). Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet 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. 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: the filter removes water and fine particulate, the regulator holds a steady setting, and the lubricator mists oil to the actuators.
Supplying the sealing heads, pushers and diverters on a packaging conveyor, where the automatic drain handles condensate on a line that runs unattended through shifts.
Conditioning air ahead of spray guns and air-assisted applicators in a finishing booth, where the 5 um element supports cleaner air and the regulator gives the operator a stable pressure setting.
Start with the port and size: this unit steps up to 3/8 inch PT in size 400, so match it to the air consumption of the tools and cylinders downstream - if your demand sits near the top of a smaller size, move up one size. Choose the drain to suit access: automatic (this unit) suits installations that are not checked daily; manual suits attended stations; differential-pressure is the default. Choose the filter grade by sensitivity of the downstream equipment: 40 um is the standard element, 5 um (this unit, code W) suits finer applications. Gauge style and scale are decodable: embedded square gauge standard, external round gauge optional, in MPa, psi or bar scales - this unit carries a round psi gauge. Thread is PT as standard; G (BSPP) and NPT are catalogue options to order.
Because flow is published as curves and not as a single rated number, we do not quote a flow figure here. Send us your application and we will confirm sizing against 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 number here. Tell us your operating pressure and the air consumption of the equipment downstream, and we will confirm the sizing against the datasheet on request.
The code GC40010AC2W decodes to the W filter grade (5 um, against the 40 um standard element) and the A drain option (automatic, against the differential-pressure default). The 5 um element suits applications that want finer particulate removal, and the automatic drain expels collected condensate without someone having to open the drain by hand.
