The AirTAC GC40015AC2WK AirTAC F.R.L. Combination, PT1/2, 5 um 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC40015AC2WK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one treatment stack. This configuration is the size 400 unit with a PT1/2 (1/2 in) PT-thread port, a 5 um filter element (the finer of the two catalogue grades), an automatic drain on the filter bowl, a round pressure gauge reading in psi, a reverse/check valve fitted, and a mounting bracket included. The bowls on the 400 size are polycarbonate (PC), and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an ambient and medium temperature range of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GC family is published in sizes 200, 300, 400 and 600, with port sizes stepping up from 1/8 in to 1 in, a choice of 40 um standard or 5 um (W) filtration, differential-pressure, automatic or manual drains, embedded square or external round gauges with MPa, psi or bar scales, and PT, G (BSPP) or NPT threads. 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: GF400-15 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 spray guns and air-assisted applicators on a paint line, where the 5 um element, regulated pressure and oil misting support finish quality at the booth.
Supplying the air cylinders and vacuum-assist actuators that index bottles along a packaging conveyor, with the automatic drain handling condensate between shifts.
Providing regulated, lubricated air to clamping cylinders on a machining-centre fixture circuit, with the psi gauge giving the operator a direct setpoint readout.
Start with the port and size step: the 400 size carries a PT1/2 port, and moving to 300 or 600 changes both the port and the flow capacity, so match the step to the air demand of the downstream circuit. Choose the drain to suit attendance: automatic drain (as fitted here) suits unattended installations, manual drain suits stations visited daily, and differential-pressure drain is the catalogue default. Choose the filter grade by sensitivity of the downstream equipment: 40 um is the standard element, 5 um (code W, fitted here) suits finer applications. Gauge scale is selectable (MPa, psi or bar; this unit carries a round psi gauge), and thread is PT as standard with G (BSPP) and NPT available as order options. Note that 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 GR400-15 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 one number. Tell us your line pressure and the air demand of your equipment and we will confirm the sizing from the datasheet on request.
The A in the code GC40015AC2WK specifies an automatic drain, which expels collected condensate from the filter bowl without an operator. The catalogue also offers manual drain (code M) and differential-pressure drain (the default, no code), so you can order the drain type that matches how often the installation is attended.
