The AirTAC GC30010ALF2WGK AirTAC F.R.L. Unit, G3/8, Low-Pressure 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 PT3/8" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator, assembled as one air-treatment set. This configuration, the GC30010ALF2WGK, is built for a 3/8 in port with G (BSPP) thread, carries the fine 5 um filter element (code W), drains condensate automatically, and uses the low-pressure regulator type with an embedded square gauge scaled in psi. A reverse/check valve is fitted and the mounting bracket is included. The filter and lubricator bowls are PC (polycarbonate) at this size.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600, with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, 40 um standard or 5 um fine filtration, gauge scale choices, and PT, G or NPT threads. 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. 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: GF300-10 filter, GR300-10 regulator and GL300-10 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 filtered, regulated and lubricated air to a welding robot's gripper and clamp circuit, where the fine 5 um element protects the valve island and the automatic drain keeps moisture out of a cell that runs unattended.
Conditioning the air supply for conveyor stopper cylinders and case-ejector actuators on a packaging line, with the lubricator delivering oil mist to keep cylinder seals working through long shifts.
Treating air for a textile or process machine that runs on a low-pressure circuit, where the low-pressure regulator type, psi-scaled square gauge and check valve give the operator a set-and-watch supply point.
Start with the port step: this unit is the size 300 set with a 3/8 in G-threaded port, one step up from 1/4 in and one below 1/2 in - match it to the line size and required flow of the machine it feeds. The automatic drain here empties the filter bowl on its own, which suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives in the family. The 5 um element (code W) is the finer choice over the standard 40 um where downstream valves and cylinders need cleaner air. The gauge is the embedded square type scaled in psi, with MPa or bar scales and an external round gauge available as options. Thread is G (BSPP) on this code; PT is the catalogue standard and NPT is also offered. A bracket is included, and the reverse/check valve holds downstream pressure if the supply drops.
One honest note on sizing: AirTAC publishes flow for this family as curves, not as a single rated number, so send us your application details and we will confirm the sizing against the datasheet before you order.
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 GR300-10 regulator with a GF300-10 filter on that branch.
AirTAC publishes flow for the GC series as curves rather than a single rated figure, so there is no one number we can honestly quote. Send us your application details and we will confirm the flow and datasheet figures for this exact 3/8 in configuration on request before you order.
The A in this code means the filter bowl drains condensate automatically instead of waiting for someone to open a manual drain. It is the practical choice for unattended or hard-to-reach installations. The family also offers manual and differential-pressure drain options if you prefer those.
