The AirTAC GC30015AC2WGK AirTAC F.R.L. Unit G1/2 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30015AC2WGK 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 around a G1/2 port, a 5 um filter element for finer protection than the standard 40 um grade, and an automatic drain that expels collected condensate from the filter bowl without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and an external round gauge with a psi scale is fitted so downstream pressure can be read directly. A reverse/check valve is included, and the mounting bracket is supplied.
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 inch, plus choices of drain type, filter grade, gauge scale and thread form (PT standard, G and NPT as order options). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. 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: GF300-15 filter, GR300-15 regulator and GL300-15 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 the clamping fixtures, tool-change cylinders and air-powered spindles of a machining centre, where the 5 um element protects fine valve seats and the check valve holds downstream pressure if the main supply dips.
Conditions the air feeding the cylinders and air-jet nozzles on a carton-forming and sealing conveyor, with the lubricator metering oil mist to extend cylinder seal life and the automatic drain clearing condensate on a line that runs unattended.
Installed as a drop-leg treatment station at a plant workbench, giving operators a regulated, lubricated and finely filtered air supply for air tools and small actuators, with the psi gauge letting the station be set and checked at a glance.
Start with the port and size step: this unit is size 300 with a G1/2 port, and larger sizes carry larger ports and more flow capacity, so match the step to the air demand of the circuit rather than oversizing on guesswork. The 5 um element (code W) suits applications that need finer particulate removal than the standard 40 um grade; the automatic drain is the right choice where the unit is not visited daily, while manual and differential-pressure drains remain available in the series. The fitted round gauge reads in psi; square embedded gauges and MPa or bar scales are the other catalogue options. Thread is G here, with PT as the standard form and NPT available to order. Because flow is published as curves and not as a single rating, send us your application details and we will confirm the sizing against the datasheet before you commit.
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 GR300-15 regulator with a GF300-15 filter on that branch.
AirTAC publishes flow for the GC series as capacity curves, not as a single rated number, so we do not quote a figure that could be misleading. Tell us your application and operating pressure and we will confirm the flow data from the datasheet on request before you order.
The A code in this model fits the automatic drain, which discharges condensate from the filter bowl by itself and suits units mounted in awkward or rarely visited positions. The series also offers a manual drain for supervised points and a differential-pressure drain as the default; all three share the same 0.15-0.9 MPa (20-130 psi) regulation range on this configuration.
