The AirTAC GC400C15F2WK AirTAC F.R.L. Combination, PT1/2 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 GC400C15F2WK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is the size 400 unit with 1/2 in PT ports, a 5 um filter element (the finer of the two catalogue grades), a differential-pressure drain on the filter bowl, an embedded square gauge reading in psi, a reverse/check valve fitted on the regulator, and a mounting bracket included. In use it dries and cleans the compressed air, holds a set downstream pressure, and carries oil mist to downstream pneumatic tools and cylinders.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port options, drain types, filter grades, gauge scales and thread forms (PT standard, with G and NPT as order options) chosen per code. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures for your application 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-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 spray guns and air-assisted applicators on a paint line, where the 5 um element, set regulator pressure and oil mist keep finish quality consistent across the booth.
Supplies the cylinders and grippers on a case-packing conveyor; the check valve holds the set pressure against back-surges and the lubricator keeps actuator seals working.
Prepares the air feeding pneumatic clamps and tool-change cylinders on a machining centre, with the psi gauge giving the operator a local set-point readout at the machine.
Start with the size and port: 400 is the second-largest of the four GC sizes (200/300/400/600), and this unit carries 1/2 in PT ports, so step up to 600 or down to 300 depending on the pipe size and air demand of the line. Choose the filter grade: this code carries the 5 um element (code W) where the standard grade is 40 um, so pick 5 um when downstream valves and instruments need finer air. The drain here is differential-pressure (the default); automatic (A) and manual (M) drains are separate codes. The gauge is the embedded square type reading psi; MPa and bar scales and an external round gauge are alternatives. Thread is PT as standard, with G (BSPP) and NPT available to order as specifications, and the bracket is included in this code.
One honest note before ordering: filter and regulator flow are published as curves, not a single rated figure, so send us your application's air demand and we will confirm sizing against the datasheet before you commit.
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, not as a single rated number, so we do not quote a figure here. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the flow and sizing against the datasheet on request before you order.
The W in the code GC400C15F2WK selects the optional 5 um grade; the catalogue standard for the GC filter section is 40 um. The 5 um element is the choice when downstream directional valves, instruments or finish-sensitive tools need cleaner air. The drain on this unit is the differential-pressure type, and automatic or manual drains are available on other codes.
