The AirTAC GC30008C2GK AirTAC F.R.L. Combination, G1/4 Port 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 GC30008C2GK is a genuine AirTAC three-unit F.R.L. combination in the GC300 series: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 3-piece set. This configuration is sized for a 1/4 inch port with G (BSPP) thread. The filter stage removes water and particulate down to the standard 40 um grade, with a differential-pressure drain that bleeds accumulated condensate automatically as pressure differential builds. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and a round external gauge with a psi scale is fitted so downstream pressure can be read directly. The lubricator meters oil mist into the air line for downstream pneumatic components, and a reverse/check valve is fitted to hold downstream settings if upstream supply is interrupted.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with a choice of ports and threads, filter grade (40 um standard, 5 um with code W), drain type (differential-pressure, automatic or manual), gauge scale (MPa, psi or bar) and the reverse/check valve option. Maximum working (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 we confirm flow and datasheet figures 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.

Feeding filtered, regulated and lubricated air to the pneumatic actuators, tool-clamp cylinders and chip-clearing jets on a machining centre, with the psi gauge giving the setter a direct readout at the machine.
Conditioning the air feeding pick-and-place and carton-closing cylinders on a packaging conveyor, where the lubricator keeps seal life up and the check valve holds the set pressure through brief supply dips.
A point-of-use F.R.L. set at an assembly bench drop, removing water and scale from the shop air line, holding a stable working pressure for air tools and screwdrivers, and oil-misting the tool circuit.
Start with the port step: size 300 carries a 1/4 inch port, and the GC family steps through 200, 300, 400 and 600 as port size and flow capacity rise - match the size to the air consumption of the downstream circuit. Choose the drain type where it applies: this unit uses the differential-pressure drain (default); automatic (code A) or manual (code M) drains are available in the family. Filter grade is 40 um standard; specify 5 um (code W) where finer particulate removal is needed. Gauge scale is selectable (MPa, psi or bar) - this configuration carries a round psi gauge. Thread is G (BSPP) here; PT is the standard thread and G/NPT are order options. A mounting 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 the GC series as curves, not as a single rated figure, so we do not quote a number. Tell us your working pressure and air consumption and we will confirm the correct size from the datasheet curves on request before you order.
The C2 suffix in GC30008C2GK specifies a round external gauge with a psi scale; the embedded square gauge with MPa/psi/bar scales is the family standard and the round gauge is the optional style. The K suffix specifies a reverse/check valve fitted, which holds the downstream setting if the upstream supply drops.
