The AirTAC GC400C15ALF2WG AirTAC F.R.L. Unit, G1/2, 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC400C15ALF2WG is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and lubricator assembled as one air-preparation set. This size 400 configuration is built for 1/2 in lines with G (BSPP) thread, carries a 5 um filter element for finer water and particulate removal, and uses an automatic drain so collected condensate is discharged without manual attention. The regulator is the low-pressure type and the set is fitted with an embedded square gauge reading in psi; a metal bowl is used on this unit, a mounting bracket is included, and the maximum inlet pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C (non-freezing).
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, and with choices of drain type, filter grade, gauge scale and thread (PT is standard; G and NPT are order options). Flow figures for this series are published as curves rather than a single rating, so ask us and we will confirm the datasheet values for your application before you order.

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-C1 filter, GR400-C1 regulator and GL400-C1 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 the tool-clamp, chip-ejection and actuation circuits of a CNC machining centre, with the 5 um element protecting fine pneumatic components on a 1/2 in supply line.
Prepares the air feeding paint spray guns on an automotive finishing line: the filter removes water and particulate, the low-pressure regulator holds a gentle setting, and the lubricator mists oil to the gun trigger and needle.
Supplies treated air to the cylinders and air jets on a packaging or cartoning conveyor, keeping moisture and debris out of the valves while the lubricator services the moving seals across a shift.
Start with the port step: size 400 with a 1/2 in port suits lines where the compressor supply and downstream demand justify the larger bore; smaller 200/300 sets or the larger 600 size exist if your flow path differs. Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your actual air demand before ordering. This unit is already decoded with the finer 5 um element (the 40 um element is the standard alternative), an automatic drain (manual and differential-pressure drains are the other catalogue choices), a low-pressure regulator, and a square gauge scaled in psi (MPa and bar scales are available). Thread is G (BSPP) here; PT is the standard thread and NPT is an order option, all stated as specification. A mounting bracket is included with this configuration.
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-C1 regulator with a GF400-C1 filter on that branch.
AirTAC publishes flow for this series as performance curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and air demand and we will confirm the datasheet curve values for the GC400 at 1/2 in port on request before you order.
The GC filter stage takes a 40 um element as standard, with 5 um available as the W-grade option; the W in this model code selects the finer 5 um element. Choose 5 um where downstream valves, cylinders or tools need finer protection, and note the automatic drain on this set discharges collected condensate without manual intervention.
