The AirTAC GC40015ALF2WG AirTAC F.R.L. Unit, G1/2 Port, 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 AirTAC GC40015ALF2WG is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built for a G1/2 (BSPP) port on the size 400 body. The filter carries a 5 um element with an automatic drain, so collected water is expelled without manual attention, and the polycarbonate bowls let you see the fluid level and condensate at a glance. The regulator is the low-pressure type and the unit arrives with an embedded square gauge reading in psi, a mounting bracket, and no reverse (check) valve fitted.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600, with a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, square or external round gauges scaled in MPa, psi or bar, and PT (standard), G or NPT threads to order. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm figures from the datasheet for your application.

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 the cylinder and gripper circuits of a carton-forming and case-sealing conveyor line, where the 5 um element keeps moisture and debris out of directional valves and the lubricator mists oil to the actuators.
Supplies the workholding clamps and tool-change cylinders on a CNC machining centre, with the low-pressure regulator holding a steady supply pressure and the psi gauge giving the operator a direct readout at the machine.
Conditions the supply to loom air jets and shed-moving cylinders in a weaving shed, where the automatic drain copes with condensate from long compressed-air runs and the lubricator protects the machine's cylinders.
Start with the port and size: this unit steps up to G1/2 on the size 400 body, the right neighbourhood for lines that have outgrown 1/4 in and 3/8 in supplies. Choose the drain to suit access: automatic (fitted here) suits units mounted high or in infrequently visited corners, manual suits attended stations, and the differential-pressure default drains only when the pressure drop warrants it. Filtration is 5 um here; the 40 um standard element is the usual choice for general actuation, while 5 um protects finer downstream components. The square gauge reads psi; MPa or bar scales and an external round gauge are alternatives. Thread is G (BSPP) on this code, with PT as the catalogue standard and G or NPT available as order options, and the bracket is included. Note that the regulator is the low-pressure type; its exact adjustment range is not published, so confirm it with us. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing 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 GR400-15 regulator with a GF400-15 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated figure, so we do not quote a number. Tell us your working pressure and the flow your line needs and we will confirm the sizing from the datasheet before you order.
The L in the code makes this a low-pressure regulator; the exact adjustment range is not published, so confirm it with us if your setpoint matters. The A gives the filter bowl an automatic drain, which expels collected condensate on its own instead of waiting for someone to open a manual drain valve.
