The AirTAC GC400C15C2W 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 GC400C15C2W is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one conditioning set. This size 400 unit is configured for 1/2 in PT ports, with the 5 um filter element (code W, against the 40 um standard), a differential-pressure drain on the filter bowl, a standard regulator with a fitted round gauge reading in psi, and the mounting bracket included. It filters water and particulate from the compressed air, holds a set downstream pressure, and meters oil mist into the air line for tools and actuators that need lubrication.
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 differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Max working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us and we will confirm the sizing and 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.

Feeds clean, regulated and lightly oiled air to the tool-changer, clamps and pneumatic actuators on a machining centre, with the 5 um element protecting the machine's valves from fine particulate.
Conditions the air feeding spray guns and air-assisted applicators on a vehicle refinishing line: water and particulate removed ahead of the regulator, with oil mist controlled by the lubricator stage.
Supplies the cylinder and vacuum-actuation circuits on a cartoning or case-packing conveyor line, holding a steady regulated pressure for consistent cycle behaviour while conditioning the air for the machine's valves.
Size 400 with 1/2 in PT ports sits in the middle of the GC range; step up to size 600 or down to size 300 if your line's flow demand points elsewhere, and match the thread to your piping: PT is the standard here, with G (BSPP) and NPT available as order options. The 5 um element in this unit is the finer of the two published grades (40 um is the standard); choose 5 um where downstream valves and instruments are sensitive to finer particulate. Drain is differential-pressure as coded; automatic (A) and manual (M) drains are the alternatives if you prefer unattended or fully manual purging. The gauge here is the external round type reading in psi; embedded square gauges and MPa or bar scales are the other published choices. A bracket is included with this unit. Because flow is published as curves and not as a single rated figure, send us your application details and we will confirm the sizing against the datasheet before you order.
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 there is no one rated flow number we can quote. Send us your line pressure and air demand and we will confirm the sizing against the datasheet on request.
The W in the code GC400C15C2W selects the 5 um element; the catalogue standard for the GC filter stage is 40 um. The 5 um grade is the finer of the two published options and suits lines with sensitive downstream valves and instruments. Drain on this unit is differential-pressure, and the round gauge reads in psi.
