The AirTAC GC30008F2GK 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 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC30008F2GK is an AirTAC GC-series three-unit F.R.L. combination: a separate filter, pressure regulator and oil-mist lubricator assembled as one air-preparation set. This size-300 configuration is built for a G1/4 (BSPP) port, carries the standard 40 um filter element with a differential-pressure drain on the filter bowl, and includes a reverse/check valve on the regulator. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and an embedded square gauge scaled in psi; an external round gauge is available as an option. Mounting bracket included.
This is a genuine AirTAC part. The GC family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including automatic or manual drains, a 5 um filter element (code W), gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing for your application on request.

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 clean, regulated and lubricated air to the tool-changer, clamps and pneumatic actuators on a CNC machining centre, with the check valve holding downstream settings if supply pressure dips.
Mounted at the drop point on an automotive assembly line, it filters line water and scale, sets a stable working pressure for impact tools and cylinders, and mists oil for air motors and cylinders.
Prepares air for the cylinders and grippers on a carton-forming and sealing conveyor, keeping moisture and debris out of the valves while the lubricator protects high-cycle actuators.
Start with the size and port: this unit is size 300 with a G1/4 port; step up to size 400 or 600 if your line needs more flow, or down to size 200 for compact points of use. Drain choice on the filter bowl is differential-pressure (standard here), automatic (code A) or manual (code M); the standard element is 40 um, with 5 um (code W) when finer particulate capture is needed. Gauge scale is selectable (MPa, psi or bar - this unit ships with a square psi gauge), and the thread can be ordered in PT (standard), G or NPT. A bracket is included. Because flow is published as curves rather than 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 this series as curves, not as a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
K means a reverse (check) valve is fitted to the regulator, so downstream pressure is held if the upstream supply drops. This unit also carries a square gauge scaled in psi, a differential-pressure drain, the standard 40 um element, and a G1/4 thread; PT is the standard thread and G or NPT are order options.
