The AirTAC AirTAC GC40015ALC2W F.R.L. Unit, 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 AirTAC GC40015ALC2W is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one air-treatment set. This configuration is built for a 1/2 in PT port and carries the fine 5 um filter element (code W) with an automatic drain, so condensate is expelled from the filter bowl without manual attention. The regulator is the low-pressure type, and this unit is fitted with an external round gauge scaled in psi. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing). The filter and lubricator bowls are PC (polycarbonate), and a mounting bracket is included.
This is a genuine AirTAC part. The GC series 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 drain, a 40 um standard or 5 um (W) filter element, standard or low-pressure regulation, gauge style and scale options, PT, G or NPT threads, and reverse/check valve variants. Flow is published as curves rather than a single rated figure, so ask us to confirm flow and datasheet figures for 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.

Feeds filtered, regulated and lubricated air to a 1/2 in pneumatic press or clamp circuit, where the 5 um element protects valves and cylinders and the low-pressure regulator suits circuits running at reduced settings.
Supplies treated air to packaging machinery and conveyor diverters on a 1/2 in main drop, with the automatic drain keeping condensate out of the line during continuous shifts and the lubricator misting downstream actuators.
Installed as a point-of-use F.R.L. on a factory assembly-cell air drop, conditioning the supply before it reaches air tools and cylinders, with the psi gauge giving operators a local pressure readout.
Start with the size step: 200, 300, 400 and 600 correspond to increasing port size and flow capacity, so match the size to the air demand of the downstream circuit - this unit sits at size 400 with a 1/2 in PT port. Choose the drain type where a bowl is fitted: differential-pressure (default), automatic (as here), or manual. Choose the filter grade: 40 um standard or 5 um (W) for finer particulate removal, as selected here. For the regulator, pick standard or low-pressure type, and select the gauge style (embedded square standard, external round optional) and scale (MPa, psi or bar - this unit has a round psi gauge). Select the thread: PT is the standard, with G (BSPP) and NPT available as order options. A bracket is included with this unit.
One honest note on sizing: flow is published as curves, not a single rated figure, so please ask us to confirm sizing 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 the GC series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your application and we will confirm the flow and datasheet figures for this 1/2 in, size 400 unit on request.
The A in the code sets the automatic drain, which expels collected condensate from the filter bowl without manual intervention - useful on lines that run unattended. The W sets the 5 um filter element instead of the 40 um standard, giving finer particulate removal ahead of the regulator and lubricator.
