The AirTAC GC400C15AC2W AirTAC F.R.L. Combination Unit, PT1/2, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15AC2W is an AirTAC GC three-unit F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one 3-piece set, so the downstream air is cleaned of water and particulate, held at a set working pressure, and carries a fine oil mist for pneumatic tools and cylinders. This configuration is the size 400 unit with a 1/2 in PT port, the fine 5 um filter element (code W), an automatic drain on the filter bowl so collected condensate is ejected without manual attention, a round pressure gauge reading in psi, and a mounting bracket included. The maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjustment range is 0.15-0.9 MPa (20-130 psi), and the working temperature range is -5 to 70 C (non-freezing). The filter bowl on this size is polycarbonate.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with matching port sizes, and with options including manual or differential-pressure drain instead of automatic, the standard 40 um element instead of 5 um, square embedded or round external gauges with MPa, psi or bar scales, and G (BSPP) or NPT threads in place of PT. 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-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 spray guns and air-assisted applicators on a paint line, where the 5 um element, a stable regulated pressure and a controlled oil mist are all wanted at the drop, and the automatic drain copes with condensate from a long supply run.
Supplying the pneumatic cylinders on a carton-forming and case-sealing conveyor, where one point of filtration, regulation and lubrication at the line keeps sealing and diverting cylinders running consistently through the shift.
Feeding the air-actuated clamps and tool-change actuators on a machining centre, where the regulator holds the clamping pressure set on the psi gauge and the lubricator mists the actuator internals continuously.
Start with the port and size step: the GC400 with its 1/2 in PT port sits in the middle of the GC range (200/300/400/600), and the right step depends on the air consumption of the machines downstream - ask us to check the published flow curves against your demand before ordering, since there is no single rated flow number to quote. Choose the drain: automatic (this unit) ejects condensate on its own, manual needs someone to open the drain, and differential-pressure draining is the default on other variants. Choose the element: 40 um is the standard grade, this unit carries the finer 5 um (W) element for cleaner air. The gauge here is the external round type reading in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available to order, and a mounting bracket is included with this unit.
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 rather than a single rated figure, so we do not quote one number. Tell us your working pressure and the air consumption of the equipment downstream, and we will confirm the sizing from the datasheet on request before you order.
The A in the code sets the automatic drain, so the filter bowl ejects collected condensate by itself instead of waiting for a manual drain; the W sets the finer 5 um element instead of the standard 40 um. Both are catalogue choices - manual or differential-pressure drains and the 40 um element are available on other GC400 variants if you prefer them.
