The AirTAC GC400-15 AirTAC F.R.L. Combination, PT1/2, 5 um Filter 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400-15 is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is sized 400 with PT1/2 ports and carries the W filter element, so the air is filtered to 5 um instead of the standard 40 um - the right choice where finer particulate and water removal matters before regulation and lubrication. The drain is the differential-pressure type, which bleeds accumulated condensate as the pressure differential across the bowl builds, and the regulator is the standard type with an external round gauge reading in psi. A mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 to 1 inch, PT (standard), G or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um (W) filter grades, and gauges in MPa, psi or bar scales. Rated flow is published as curves rather than a single figure, so ask us and we will confirm the datasheet and flow figures for this model 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: GF400-15 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.

Feeding a CNC machine tool's pneumatic circuits - clamps, tool changers and air blasts - through one PT1/2 drop: the 5 um element protects fine valves, the regulator holds set pressure and the lubricator mists oil for air cylinders.
Conditioning the air feeding a cartoning or wrapping line's conveyor diverters and sealing cylinders, where the differential-pressure drain keeps condensate off the bowls and the psi gauge lets line staff verify set pressure at a glance.
Installed at the point of use on a paint booth's compressed-air drop, where the 5 um filter grade reduces water and particulate carryover ahead of regulation and the lubricator oils the air tools used in masking and finishing work.
Start with the size and port step: 400 is a mid-large frame, and the PT1/2 port should match or exceed the air line feeding your machine so the combination does not throttle supply. Choose the filter grade deliberately - 40 um is the standard element and suits general plant air, while the 5 um (W) element fitted here suits finer protection downstream; note that finer filtration increases element loading, so drain choice matters. The drain options are differential-pressure (default, as fitted), automatic, or manual - pick automatic where bowls are hard to reach, manual where you want positive operator control. For the gauge, embedded square is standard and external round is optional, with MPa, psi or bar scales; this unit carries the round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options, and a bracket is included.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so we cannot quote you a number here. Send us your application and we will confirm 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 GR400-15 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 we do not quote a number on the page. Tell us your application and required flow, and we will confirm the datasheet and flow figures for this exact model on request before you order.
The W code in GC40015C2W selects the optional 5 um element in place of the 40 um standard, giving finer particulate and water removal - useful before sensitive valves or finishing processes. The drain is the differential-pressure type, which discharges accumulated condensate automatically as the pressure differential across the bowl builds; automatic and manual drains are available as order options.
