The AirTAC GC40015F2W AirTAC F.R.L. Unit 1/2 in PT, 5 um, psi Gauge 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC400 series is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This configuration is size 400 with a PT1/2 (1/2 in) PT thread, the finer 5 um filter element (code W), a differential-pressure drain on the filter bowl, and the embedded square gauge fitted with a psi scale. The standard regulator covers an adjustment range of 0.15-0.9 MPa (20-130 psi), the polycarbonate bowls suit the 400 size, and the mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC line is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um (W) filtration, MPa, psi or bar gauge 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 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.

A paint line needs clean, regulated and lubricated air at each booth drop. This unit filters water and particulate down to 5 um, holds the regulator at the set pressure, and mists oil into the supply for air tools and cylinders on the line.
Carton sealers and wrapping machines run continuously on shop air. This F.R.L. set at the machine inlet removes condensate and 5 um particles, keeps supply pressure steady for consistent actuator speed, and lubricates the valve-and-cylinder circuit.
Pneumatic clamps and fixtures on a machining centre need stable, conditioned air. This unit conditions the drop before the clamping circuit: 5 um filtration protects the valves, the regulator holds clamping pressure, and the lubricator feeds the cylinders.
Start with the port step: size 400 carries a 1/2 in PT connection, and the correct size is chosen against the flow your line needs - we can confirm the published flow curves against your demand before you order. For the filter stage you chose the 5 um element (code W) over the 40 um standard, which suits downstream equipment that needs finer particulate removal; the drain on this unit is the differential-pressure type (automatic A and manual M are the other catalogue options). The gauge is the embedded square type with a psi scale; MPa and bar scales and an external round gauge are also available. Thread is PT as standard, with G (BSPP) and NPT as order options, and the mounting bracket is included.
One honest note on sizing: AirTAC publishes flow as curves, not a single rated number, so please ask us to confirm the datasheet figures for this exact model 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 this series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Tell us your application and we will confirm the datasheet flow curves and check the sizing of this 1/2 in unit against your demand on request.
The W in the code GC40015F2W selects the finer 5 um filter element instead of the 40 um standard, which suits downstream equipment that needs finer particulate removal. The blank drain position is the differential-pressure type; automatic (A) and manual (M) drains are the other catalogue options if you prefer a different drainage method.
