The AirTAC GC40015LF2WK AirTAC F.R.L. Unit, 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC40015LF2WK 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 built around a 1/2 in PT port, with a 5 um filter element (the finer of the two published grades), a differential-pressure drain on the filter bowl, a low-pressure type regulator with an embedded square gauge scaled in psi, a reverse/check valve fitted on the regulator, and a mounting bracket included. In service, the filter strips water and particulate from the compressed air, the regulator holds a steady low downstream pressure, and the lubricator meters oil mist into the supply for downstream air tools and cylinders.
This is a genuine AirTAC part from the GC series, which spans sizes 200 to 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus drain, filter-grade, gauge-scale and reverse-valve choices. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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. 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.

Feeding spray guns and air-assisted applicators on a paint line, where the 5 um element, steady low-pressure regulation and oil misting keep finish quality consistent through the shift.
Supplying the cylinders and grippers that erect, fill and seal cartons on a packaging conveyor, with the reverse/check valve helping hold downstream pressure if the upstream supply dips.
Running clamps, vise actuators and air chucks on machining cells, where filtered, regulated, lightly oiled air keeps clamping action repeatable and tooling lubricated.
Start with the port and size: this unit steps up to the 400 size at 1/2 in PT, so check it against the air consumption of the machines it will feed - larger sizes carry larger ports and more flow capacity. Because flow is published as curves and not as a single rating, ask us to confirm sizing against your application before ordering. Other decodable choices: the 5 um element here is the finer option (40 um is the standard grade); the differential-pressure drain is the default and automatic (A) or manual (M) drains are orderable; the square gauge is fitted here scaled in psi, with MPa or bar scales and an external round gauge available; PT is the standard thread with G and NPT as order options; and the bracket is included. Note this is the low-pressure type regulator - its exact adjustment range is not published in the material we hold, so confirm the range with us for your set pressure.
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 number, so we do not quote a figure that is not in our validated data. Tell us your line pressure and the air consumption of the equipment you will feed, and we will confirm the sizing against the datasheet curves on request before you order.
The L in the code marks the low-pressure type regulator, intended for circuits that hold a lower downstream pressure than the standard type; its exact adjustment range is not published in our data, so confirm it with us. The W marks the 5 um filter element, the finer of the two published grades (40 um is standard) - choose 5 um where downstream valves, cylinders or tools need cleaner air. Both are fixed by the code, not field-changeable choices.
