The AirTAC GC400C15MLC2WGK AirTAC F.R.L. Unit G1/2 5 um Low-Pressure 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 filter, regulator and lubricator assembled as one set to clean, regulate and oil-mist lubricate compressed air. This GC400C15MLC2WGK is built for G1/2 ports and carries the 5 um filter element (code W) for finer water and particulate removal, a manual drain on the filter bowl, a low-pressure regulator, a round gauge scaled in psi, a reverse/check valve, and a mounting bracket. The polycarbonate bowl keeps the filter condition visible, and the set handles a maximum inlet pressure of 1.0 MPa (145 psi) at -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC family spans sizes 200 to 600 with ports from 1/8 to 1 inch, and options for drain type, filter grade, gauge style and scale, thread (PT standard, with G and NPT available to order) and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures for your application before ordering.

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 the pneumatic grippers and pushers on a bottling line with filtered, regulated and lubricated air, with the low-pressure regulator matching circuits that run below standard working pressures.
Conditions the air feeding clamping cylinders on a machining centre: the 5 um element protects fine valve internals, the regulator holds set pressure and the lubricator mists oil for cylinder seals.
Supplies the air cylinders that raise stops and divert products on a packaging conveyor, with the reverse/check valve holding downstream pressure and the round psi gauge giving a local reading.
Size 400 with G1/2 ports sits in the middle of the GC range; step up or down through sizes 200 to 600 as your flow demand changes, since larger sizes carry larger ports and more flow. The 5 um element (code W) suits air feeding sensitive components, while the standard grade is 40 um. Manual drain means an operator drains the filter bowl during checks; automatic and differential-pressure drains are available if you prefer unattended drainage. The low-pressure regulator on this unit is intended for circuits below standard working ranges - confirm its exact range with us. The fitted round gauge reads in psi; embedded square gauges and MPa or bar scales are alternatives. PT is the standard thread, with G and NPT catalogue options to order, and a bracket is 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 the GC series as curves, not a single rated number, so we do not quote a figure here. Tell us your application and we will confirm the datasheet flow curve for the 400 size at G1/2 before you order.
The W code fits the 5 um element instead of the standard 40 um, for finer particulate removal ahead of sensitive tools and valves. Manual drain means an operator drains the filter bowl during checks; automatic and differential-pressure drain versions are available if you want unattended drainage.
