The AirTAC GC30008AF2WGK AirTAC F.R.L. Combination, G1/4 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 PT1/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008AF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply unit. This configuration is built around a G1/4 (BSPP) port in the 300 size. The filter stage carries the 5 um element (code W) for finer water and particulate removal than the standard 40 um grade, with an automatic drain that expels collected condensate without manual attention. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), an embedded square gauge reading in psi, and a reverse/check valve (code K) fitted downstream. The lubricator mists oil into the air line for downstream pneumatic components. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). The bowls on the 300 size are polycarbonate (PC); only the 600 size uses aluminium alloy.
This is a genuine AirTAC part. The GC family is available in 200, 300, 400 and 600 sizes with port sizes from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drains, 40 um or 5 um filter grades, gauge scale options, and PT, G or NPT threads. Flow figures for this series are published as curves rather than a single rated number, so ask us to confirm the datasheet and sizing 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: GF300-08 filter, GR300-08 regulator and GL300-08 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 a bank of air tools and cylinders at an assembly workstation, where the 5 um element protects directional valves, the regulator holds set pressure and the lubricator keeps tool seals conditioned.
Supplying the clamp, pusher and divert cylinders on a packaging conveyor, with the check valve holding downstream pressure and the automatic drain keeping condensate out of the valve manifold.
Conditioning the shop-air feed to a CNC machine's tool-change and clamping circuits, where the 5 um grade, regulated pressure and metered oil mist support consistent actuator and valve operation.
Start with size and port: the 300 size with its 1/4 in port suits mid-range supply lines, while 200, 400 and 600 sizes step up or down in port and flow capacity - match the step to the air demand of the circuit rather than oversizing on guesswork. Choose the drain to suit access: automatic (as fitted here) where the unit is hard to reach, manual where an operator is on hand, or the differential-pressure default. Choose the filter grade: 40 um is standard for general supply; the 5 um element on this unit suits finer protection of valves and cylinders. Select the gauge scale (MPa, psi or bar) and thread (PT standard, G or NPT to order); a bracket is included on this unit. Because flow for this series is published as curves and not as a single rated figure, 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 GR300-08 regulator with a GF300-08 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, Cv or SCFM number. Tell us your line size and air demand and we will confirm the flow data from the datasheet for this exact model on request before you order.
The GC combines three separate bodies - filter, regulator and lubricator - so each stage can be serviced or replaced on its own, and the filter and lubricator sit either side of the regulator. A GFC two-unit set merges the filter and regulator into one body and suits tighter panels where fewer joints matter. Both cover filtration, regulation and lubrication; the choice is service layout, not function.
