The AirTAC GC400C15ALC2WG AirTAC F.R.L. Combination, G1/2, 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 lubricator assembled as one unit. This GC400C15ALC2WG is the 400 size with a G1/2 (BSPP) port, an automatic drain on the filter bowl, a 5 um filter element (the finer of the two published grades), a low-pressure regulator and a round pressure gauge reading in psi. In service it removes water and particulate from compressed air, holds a set downstream pressure and meters oil mist into the line, all from a single mounted assembly with the bracket included.
This is a genuine AirTAC part. The GC range is published in 200, 300, 400 and 600 sizes with ports from 1/8" to 1", a choice of automatic, manual or differential-pressure drains, 40 um standard or 5 um (W) filtration, standard or low-pressure regulators, and gauges scaled in MPa, psi or bar. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures on request before you order.

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 impact wrenches, nutrunners and air ratchets at assembly stations, where the filter stage strips water and swarf, the regulator holds tool supply pressure and the lubricator mists oil into the tool air.
Supplying a low set pressure to light-duty clamps and swing cylinders, with the 5 um element protecting the fine metering and valve internals downstream of the unit.
Feeding the cylinders and air grippers that erect and seal cartons, keeping moisture and particles out of the valves while the lubricator conditions the actuator seals in continuous shift running.
The real choices in this family are the size and port step (200/300/400/600, 1/8" to 1"), matched to the flow your line needs; the drain type on the filter bowl (automatic here, or manual or differential-pressure); the filter grade (40 um standard, 5 um/W where finer filtration matters); the regulator type (standard or low-pressure) and the gauge scale (MPa, psi or bar); and the thread (PT is the standard, G or NPT are order options). This unit carries the low-pressure regulator type, a 5 um element, an automatic drain and a psi-scaled round gauge, with a mounting bracket included. Flow is published as curves, not a single rating, so 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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for this series as characteristic curves rather than a single rated figure, so there is no one l/min or SCFM number we can honestly quote. Tell us your working pressure and the air demand of the equipment downstream, and we will confirm the sizing against the datasheet curves on request before you order.
The L marks the low-pressure type of regulator, intended for applications set well below standard line pressures; the exact adjustment range for this type is not published in the sheet we work from, so we confirm it on request. The A sets an automatic drain on the filter bowl, which discharges collected condensate by itself instead of relying on manual draining or a differential-pressure signal.
