The AirTAC GC400C15MLC2W AirTAC F.R.L. Combination, 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 GC series is AirTAC's three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator built up as one supply package, so the same assembly removes water and particulate, holds a set downstream pressure and meters oil mist into the line. This GC400C15MLC2W is a size 400 unit with a PT1/2 port, a 5 um filter element, a manual drain on the filter bowl, a low-pressure regulator and a round pressure gauge scaled in psi.
This is a genuine AirTAC part. The GC range spans sizes 200 to 600 with ports from 1/8 to 1 inch, and options including differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge style and scale, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your application.

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.

Supplies filtered, regulated and lubricated air to the clamping and tool-change cylinders on a machining centre, with 5 um filtration ahead of sensitive valves and oil mist keeping cylinder seals supple.
Feeds the stopper, pusher and lift cylinders along a bottling conveyor, holding a steady low set pressure for gentle container handling while the lubricator mists oil into continuously cycling actuators.
A point-of-use F.R.L. for assembly benches running impact drivers and riveters: water and fine particulate removed at 5 um, pressure set locally at the bench, and oil mist carried out to the air tools.
Size 400 with a PT1/2 port is chosen by matching the port step and the size's flow capability to the line it feeds - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. The C2W decode gives a round external gauge scaled in psi (the embedded square gauge with MPa, psi or bar scales is the standard alternative), a manual drain you open by hand instead of the differential-pressure default, and the W 5 um element in place of the 40 um standard. The L code makes this a low-pressure regulator; the exact range is not published, so confirm it against your set pressure. Thread is PT as standard, with G and NPT as order options.
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 a number here. Tell us your working pressure and air consumption and we will confirm the datasheet curve figures for this exact model on request.
M sets a manual drain you open by hand instead of the differential-pressure default. L makes the regulator a low-pressure type; the exact range is not published, so confirm it with us against your set pressure. C2 fits the round external gauge scaled in psi. W swaps the standard 40 um element for a 5 um one. Everything else follows the GC400 standard build.
