The AirTAC GC400C15AF2WG AirTAC F.R.L. Combination, G1/2 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15AF2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This configuration is the 400 size with G1/2 (BSPP) ports, fitted with the 5 um filter element (code W), an automatic drain on the filter bowl, a standard regulator adjustable from 0.15-0.9 MPa (20-130 psi), and the embedded square gauge scaled in psi. A mounting bracket is included and no reverse/check valve is fitted. The filter and lubricator bowls on this 400 size are polycarbonate (PC); maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family is published in 200, 300, 400 and 600 sizes with a choice of PT (standard), G or NPT threads, 40 um standard or 5 um fine filtration, differential-pressure, automatic or manual drains, and gauge scales in MPa, psi or bar. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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-C1 filter, GR400-C1 regulator and GL400-C1 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 CNC cell: the 5 um element protects fine valves from particulate, the regulator holds a steady set pressure for repeatable clamping, and the lubricator mists oil to the actuator seals.
Supplying the cylinders and grippers on a carton-forming and sealing line, where the automatic drain clears condensate through long shifts without an operator, the square psi gauge gives a visible set point, and lubricated air keeps high-cycle cylinders running.
Conditioning air at the drop to paint guns and air tools in a body shop: water and 5 um-grade particulate are removed before the regulator, the set pressure is held steady at the gun, and the oil-mist lubricator serves downstream air tools only where specified.
Step through the real choices before ordering a GC combination. First pick the size and port: 200, 300, 400 and 600 step up in port and flow capacity, so match the size to the air demand of the machine rather than only to the existing pipe thread - here the 400 size gives a 1/2 in port. Second, choose the drain: differential-pressure (the default), automatic (as on this model, which ejects condensate without daily attention) or manual. Third, choose the filter grade: 40 um standard or 5 um with code W, which this unit carries for finer particulate protection downstream. Then set the gauge scale (MPa, psi or bar - this one is psi) and the thread: PT is the standard, with G (BSPP) and NPT available as catalogue options to order. A bracket is included; a reverse/check valve (code K) is a separate option and is not fitted here. Because flow in this series is published as curves and not as a single rated number, send us your application's air demand and we will confirm the 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for the GC series as performance curves, not as a single rated figure, so we do not quote one number. Tell us your application's air demand and line pressure and we will confirm the sizing from the datasheet on request before you order.
Both are read straight from the code: A in the drain position means the filter bowl drains condensate automatically instead of the differential-pressure default or a manual drain, and W in the filter position selects the 5 um element instead of the 40 um standard. Choose manual drain if you prefer a controlled, operator-checked blowdown; choose 40 um if coarser protection is sufficient.
