The AirTAC GC40015AC2W 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 GC40015AC2W is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 400-size unit with a PT1/2 (1/2 in) port. This configuration carries an automatic drain on the filter bowl, so collected condensate is discharged without manual attention, and a fine 5 um filter element (the W grade, in place of the 40 um standard) for cleaner downstream air. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an external round gauge scaled in psi is fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), operating temperature is -5 to 70 C (non-freezing), and the bowls are polycarbonate (PC) at this size. A mounting bracket is included.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with matching port sizes, and options include manual or differential-pressure drains, the 40 um or 5 um filter grade, embedded square or external round gauges with MPa, psi or bar scales, and PT, G (BSPP) or NPT threads. Flow for this series 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. 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.

Feeds filtered, regulated and lubricated air to the clamping fixtures, tool changers and pneumatic actuators on a CNC machining centre, with the 5 um element protecting fine valve internals on a 1/2 in main.
Conditions the air feeding cylinder-driven carton formers, sealers and diverters on a packaging conveyor line, where the automatic drain copes with condensate on a line that runs unattended through shifts.
Installed at the drop-leg of a compressed-air ring main in an assembly plant, delivering clean, pressure-set and oil-misted air to hand-held pneumatic tools and workholding clamps at each station.
Start with the port step: this unit is size 400 with a PT1/2 connection, and the 200/300/400/600 sizes step up in both port and airflow capacity, so match the size to the air demand of the circuit. Choose the drain to suit access: automatic (as decoded here) suits installations that are not checked daily, manual drain suits attended setups, and differential-pressure drain is the catalogue default. Choose the filter grade by air-quality need: 40 um is standard for general protection, 5 um (this unit, code W) for finer particulate removal. Gauge scale (MPa, psi or bar) and thread (PT standard, with G and NPT as order options) should match the plant convention, and a bracket is included for panel or frame mounting.
One honest note before ordering: airflow for this series is published as performance curves, not a single rated number, so we do not quote a rated flow figure. Send us your application details and we will confirm the 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 airflow for the GC series as performance curves rather than a single rated figure, so we do not state a rated flow number for this unit. Tell us your application and air demand and we will confirm the sizing against the datasheet on request.
The code GC40015AC2W decodes with A for an automatic drain, which discharges condensate from the filter bowl without manual intervention - useful where the unit is mounted in a position that is not checked daily. The trailing W sets the 5 um filter grade instead of the 40 um standard, for finer particulate removal upstream of the regulator and lubricator.
