The AirTAC GC40015ALF2W AirTAC F.R.L. Combination, PT1/2, 5 um Filter 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 GC40015ALF2W is an AirTAC GC400 three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one air-preparation set. This configuration is built for 1/2 in PT ports, carries the W filter element (5 um filtration against the 40 um standard) and uses an automatic drain on the filter bowl, so condensate is expelled without manual attention. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi; a reverse/check valve is not fitted. The filter and lubricator bowls are polycarbonate (only size 600 uses aluminium alloy), a mounting bracket is included, and the unit is rated for 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 series spans sizes 200, 300, 400 and 600 with port options from 1/8 to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um (W) filtration, gauge scales in MPa, psi or bar, and G (BSPP) or NPT threads as order options. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures against 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. 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.

Installed ahead of a machining centre's pneumatic circuit, this unit filters water and fine particulate from the shop air, holds a steady regulated supply to clamps and tool-change actuators, and mists oil for cylinder and valve lubrication - one set feeding the whole cell.
Mounted at the drop of a packaging conveyor's air main, it conditions the supply feeding case sealers, diverters and pusher cylinders, keeping condensate and grit out of the valves while the regulator holds the actuator circuit steady through shift-long cycling.
Fitted at a workstation manifold in an assembly plant, it delivers filtered, regulated and lubricated air to impact drivers, air ratchets and pneumatic press cylinders, protecting the tools and giving operators a local gauge to read the circuit pressure at a glance.
The real choices within the GC line are the size and port step, the drain type, the filter grade and the gauge. Size 400 with PT1/2 ports suits larger-bore distribution lines; step down to 200/300 or up to 600 if your porting or demand differs - we confirm the flow curves against your requirement before you order. Drain: this unit is automatic; manual and differential-pressure versions exist if you prefer scheduled draining or a drain tied to pressure drop. Filtration: 5 um (W) here versus the 40 um standard - choose 5 um where downstream valves and cylinders are sensitive to fine particulate. Gauge: the embedded square gauge is standard, scaled in psi here; MPa or bar scales and an external round gauge are options. Thread: PT is the standard; G (BSPP) and NPT are catalogue options to order. The regulator on this unit is the low-pressure type; its exact adjustment range is not published, so confirm it with us if your line pressure sits near the limits.
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 here. Tell us your application and we will confirm the datasheet flow curve and sizing for this unit on request before you order.
The A in the code sets an automatic drain on the filter bowl: condensate is expelled without anyone opening the drain, which suits unattended compressors and lines. Manual and differential-pressure drain variants exist in the same series if your maintenance routine prefers them - ask us to quote the equivalent code.
