The AirTAC GC40015LC2WK 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 PT1/2" ports, a 5 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015LC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one complete air-treatment set. This 400-size configuration is ported PT1/2, carries the 5 um filter element (code W) instead of the standard 40 um, and uses a differential-pressure drain on the filter bowl. The regulator is the low-pressure type, and this unit is fitted with a round external pressure gauge on a psi scale plus a reverse/check valve (code K). All bowls on this size are PC (polycarbonate), and the mounting bracket is included.
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, PT as the standard thread and G (BSPP) or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale in MPa, psi or bar, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds clean, regulated and lubricated air to a machining centre's clamping fixtures, tool-change cylinders and pneumatic gates from a 1/2 in shop-air drop, with the 5 um element protecting fine pilot valves.
Conditions the air feeding spray guns and air-assisted equipment on a paint line, where the 5 um grade and oil-mist lubrication support consistent gun operation at the booth.
Supplies the cylinders and air-driven diverters on a packaging or bottling conveyor, with the regulator holding a stable low-pressure setting and the check valve holding downstream pressure if the supply dips.
Start with the port step: this unit is the 400 size at PT1/2, one step above the 300 series, so step up or down according to the air demand of the circuit - flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering. This configuration already fixes several choices: 5 um filtration (the W element, one grade finer than the 40 um standard), a differential-pressure drain, the low-pressure regulator type, a round gauge on a psi scale, and a fitted reverse/check valve. If you would rather have the standard 40 um element, an automatic or manual drain, a square embedded gauge, or an MPa or bar scale, those are available in the same family. Thread is PT as standard; G (BSPP) and NPT versions are order options, and the mounting bracket is included with this unit.
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 this family as performance curves rather than a single rated figure, so we do not quote one number. Tell us your application and we will confirm the flow and sizing from the datasheet on request before you order.
L marks the low-pressure regulator type, and K means a reverse/check valve is fitted, so downstream pressure is held if the supply line loses pressure. The code also shows C2 (round gauge, psi scale) and W (5 um filter element instead of the 40 um standard); the drain is the differential-pressure type, the standard default.
