The AirTAC GC400C15F2WGK AirTAC F.R.L. Combination, G1/2 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one supply unit that cleans, regulates and lubricates compressed air downstream. This GC400 configuration is built for 1/2 in ports with G (BSPP) thread, carries the fine 5 um filter element (code W) instead of the 40 um standard, and drains the filter bowl by differential pressure, so the bowl purges as the pressure across the element builds. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), a psi-scale gauge is fitted so the set pressure can be read directly, and a reverse/check valve (code K) holds downstream pressure if the upstream supply drops. The mounting bracket is included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, so the same three-unit layout is available from 1/8 in up to 1 in ports, with manual or automatic drain, 40 um or 5 um filtration, MPa, psi or bar gauge scales, and PT, G or NPT threads as order options. AirTAC publishes flow for this series as curves rather than a single rated figure, so ask us and we will confirm the sizing and datasheet figures for your application 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.

Feeds clean, regulated and lubricated air to the tool-change clamps, pneumatic chucks and coolant-mist circuits of a machining centre, with the 5 um element protecting fine spool valves on a 1/2 in shop-air drop.
Supplies the diverters, sealers and vacuum generators along a packaging conveyor, where the check valve keeps actuators from drifting if the main supply dips mid-cycle and the lubricator mists the cylinder seals.
Mounted at the drop of a plant-air header in an assembly cell, it conditions air for impact tools, clamping fixtures and air-fed workstations, with the psi gauge letting maintenance set and verify the cell pressure.
Start with the port and size step: this unit is size 400 with 1/2 in G-thread ports; if your line needs less or more air, the same combination exists in sizes 200, 300 and 600. You have already chosen the fine 5 um element (W); the 40 um standard element suits general plant air and loads the drain less, so step down to 5 um only where downstream valves, cylinders or instruments need the cleaner air. The differential-pressure drain is hands-off; a manual-drain (M) or automatic-drain (A) version can be ordered instead if your duty cycle or bowl orientation calls for it. Gauge scale is set here to psi; MPa or bar scales are available, and an embedded square gauge can replace the fitted round gauge. Thread is G (BSPP) on this code, with PT as the standard and NPT as an order option, and the bracket is included. Flow for the GC series is published as curves, not a single rating, so send us your air demand and we will confirm the correct size 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 performance curves, not as a single rated figure, so we do not quote one number. Tell us your air demand and line pressure and we will confirm the sizing against the datasheet on request before you order.
The W in the code GC400C15F2WGK selects the optional 5 um filter element in place of the 40 um standard. Choose 5 um where downstream valves, instruments or air-fed equipment need finer particle removal; choose 40 um for general plant air. Both grades are available across the GC range, and the drain choice (differential-pressure, automatic or manual) is independent of the grade.
