The AirTAC GC400-15AF2W 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 PT1/2" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400-15AF2W 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. On this configuration the filter element is the 5 um grade (the W option, against the 40 um standard) with an automatic drain, the regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and an embedded square gauge scaled in psi, and the lubricator feeds oil mist downstream to pneumatic tools and cylinders. The port is PT1/2 (PT thread as standard), maximum inlet pressure is 1.0 MPa (145 psi), the bowls on the filter and lubricator are polycarbonate at this size, and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, a choice of PT, G (BSPP) or NPT thread, manual, automatic or differential-pressure draining, 40 um or 5 um filtration, and gauge scale options. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the 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. 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: GF400-15 filter, GR400-15 regulator and GL400-15 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.

Supply filtered, regulated and lubricated air to the clamping fixtures, tool-change cylinders and air-powered accessories on a machining centre, with the 5 um element protecting the machine's directional valves.
Feed spray guns and air-driven applicators at a paint line, where the regulator holds a stable set pressure, the 5 um filtration limits water and particulate in the finish, and the lubricator conditions downstream air tools.
Serve the cylinders and air cylinders on a carton-forming and sealing line from one conditioned supply point, keeping the pressure constant across shift-length cycles and draining condensate automatically.
Start with the port step: this unit is size 400 with a PT1/2 port; smaller and larger sizes in the GC family step the port and flow capacity up or down, so match the size to the air demand of the circuit rather than the pipe alone. Choose the drain: automatic (fitted here) drains the filter bowl without operator attention, manual suits attended installations, and differential-pressure draining is the catalogue default. Choose the filter grade: 40 um is standard for general supply, while the 5 um element fitted here suits finer protection of valves and tools. Select the gauge scale (MPa, psi or bar - psi here), the thread (PT standard, G or NPT to order), and whether a mounting bracket is needed. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering.
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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so no rated flow number, Cv or SCFM value is stated here. Tell us your application and required flow, and we will confirm the datasheet figures for this size before you order.
The W in the code GC40015AF2W selects the 5 um filter element instead of the 40 um standard, and the A selects an automatic drain instead of the differential-pressure default. Other configurations in the same GC400 size are available with the 40 um element and with manual or differential-pressure draining - just ask for the code you need.
