The AirTAC GC30008C2G 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 GC30008C2G is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set for compressed air. This size 300 configuration carries a G1/4 (1/4 in) port with G thread, the standard 40 um filter element, and a differential-pressure drain on the filter bowl. The regulator is the standard type with a 0.15-0.9 MPa (20-130 psi) adjustment range, and this code includes a round pressure gauge with a psi scale. The polycarbonate bowls suit the -5 to 70 C (non-freezing) operating range, with a maximum working pressure of 1.0 MPa (145 psi).
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of ports, thread options (PT standard; G and NPT as order options), drain types, a 5 um filter element (code W), gauge scale and reverse/check valve. 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.

A central compressed-air drop feeding a packaging hall: the filter removes water and particulate from the main line, the regulator holds a steady working pressure for the machines, and the lubricator meters oil mist to downstream air tools and cylinders.
Conveyor diverters and stopper cylinders need clean, regulated, lubricated air to cycle reliably shift after shift. This three-unit set at the line drop conditions the supply before it reaches the valve manifold and actuators.
Assembly benches with air impact drivers, riveters and clamps benefit from one conditioned supply point: filtered water-free air, a set pressure for consistent tool torque, and oil mist to keep the tools lubricated through the day.
Start with the size and port: step 200/300/400/600 up or down against the flow your line needs - here size 300 with a 1/4 in port. Because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. Then pick the decodable options: drain type (differential-pressure as on this unit, automatic, or manual - note the manual-drain regulator range starts lower at 0.05 MPa), filter grade (40 um standard, 5 um with code W), gauge type and scale (embedded square standard, external round optional, in MPa, psi or bar - this code carries a round psi gauge), thread (PT standard; G or NPT to order), and the reverse/check valve where backflow protection is wanted.
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 number, so there is no one figure we can quote. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the flow and datasheet figures for this size 300, G1/4 unit on request before you order.
This configuration uses the default differential-pressure drain, which bleeds condensate from the filter bowl automatically as the pressure differential across the element builds. If you prefer, GC units can be ordered with an automatic drain (code A) or a manual drain (code M); note that with a manual drain the regulator adjustment range starts lower, at 0.05-0.9 MPa (7-130 psi) instead of 0.15-0.9 MPa (20-130 psi).
