The AirTAC GC400C15AC2WK AirTAC F.R.L. Combination, PT1/2 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 GC400C15AC2WK is a genuine AirTAC GC-series three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit. This size 400 configuration is built for a 1/2 in PT port and carries the fine 5 um filter element (code W) instead of the standard 40 um grade, so both water and fine particulate are stripped before air reaches the regulator and lubricator. The filter bowl drains automatically, the regulator is the standard type with a fitted round gauge scaled in psi, and a reverse/check valve is fitted to hold the downstream setting. At size 400 the bowls are polycarbonate. The maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and the unit operates from -5 to 70 C in non-freezing conditions. A mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options that include manual or differential-pressure drains, a 40 um standard element, gauge scale choices in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. 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.

At a 1/2 in plant air drop, this F.R.L. set conditions the supply feeding impact wrenches, nut runners and pneumatic clamps: water and fine particles removed at 5 um, pressure held steady by the regulator, and a controlled oil mist carrying the tools.
Packaging machines and palletiser cylinders run for thousands of cycles a shift. This unit gives that line clean, regulated and lubricated air at the half-inch feed, with the check valve helping hold the set pressure and the automatic drain keeping the bowl clear unattended.
CNC and special-purpose machines with air-assisted tool changes, clamping and chip ejection need one conditioned supply point. This three-unit set mounted on its bracket at the machine inlet delivers filtered, regulated, lubricated air to those circuits from a 1/2 in PT connection.
Start with the port and size step: size 400 with a 1/2 in PT port sits in the upper-middle of the GC range (200/300/400/600), so step up to 600 or step down to 300 according to the flow your line needs - we will confirm the flow curve against your demand before you order. This unit already carries the fine 5 um element (the standard is 40 um; choose W only where downstream valves and cylinders genuinely need finer air). The automatic drain here empties the filter bowl without daily attention; manual and differential-pressure drain versions exist if you prefer a different regime. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are the alternatives. Thread is the PT standard - G (BSPP) and NPT are catalogue options to order as specification, not a delivery matter. A mounting bracket is included with this configuration.
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 curves, not as a single rated number, so we do not quote a figure here. Tell us your line demand and working pressure and we will confirm the flow curve and correct size from the datasheet on request before you order.
The W in the code specifies the optional 5 um filter element instead of the 40 um standard, for finer water and particulate removal ahead of the regulator and lubricator. The A specifies an automatic drain, which expels collected condensate from the filter bowl without manual attention - manual and differential-pressure drain versions are available if your maintenance regime prefers them.
