The AirTAC GC30008F2WGK 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 differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC30008F2WGK is a three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one unit. This configuration is sized 300 with a G1/4 (BSPP) port, carries the W filter element for 5 um filtration (finer than the 40 um standard), uses the differential-pressure drain that bleeds the bowl automatically as flow passes, and is fitted with an embedded square gauge reading in psi. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, a reverse/check valve is fitted to hold downstream pressure if the supply drops, and a mounting bracket is included. The filter and lubricator bowls are PC (polycarbonate).
This is a genuine AirTAC part from the GC series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, drain, filter-grade, gauge-scale, thread and check-valve options. Flow figures for the series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing for your application.

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.

Feeds filtered, regulated and lubricated air to the tool-clamp and pallet-changer circuits of a machining centre, with the 5 um element protecting tight-tolerance valves and the psi gauge giving operators a familiar readout.
A single conditioning point for the pick-and-place cylinders and sealing jaws on a packaging line: water and particulate removed upstream, pressure held steady by the regulator, and oil mist carried to the cylinders, with the check valve holding settings through brief supply dips.
Conditions the air feeding a valve manifold in a robotic assembly cell, where the 5 um grade guards the directional valves, the lubricator services the actuators downstream, and the bracket mounts the set cleanly beside the manifold.
Choose the GC size by the port and flow your line needs: this 300 unit steps up to G1/4; larger sizes carry larger ports and more flow, which we confirm from the curves before you order. The W element here gives 5 um filtration - keep it only if your actuators or valves need the finer grade, since the 40 um standard element suits general supply. Drain choice matters: the differential-pressure drain fitted here needs flow to purge the bowl, so pick an automatic drain for idle lines or a manual drain where you want full control. Gauge scale is psi on this unit (MPa and bar scales exist), and the fitted check valve holds downstream settings against supply loss. Thread is G (BSPP); PT is the catalogue standard and NPT is orderable as an option. Flow is published as curves, not a single rating - 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, not as a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The W in the model code specifies the optional 5 um element. It suits circuits with sensitive valves or components that need finer filtration; the 40 um element remains the standard choice for general supply, and both grades are available across the GC range.
