The AirTAC GC30008C2K AirTAC F.R.L. Combination PT1/4 Round Psi Gauge 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 GC30008C2K is a three-piece AirTAC GC F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled into one conditioning station. This unit is sized GC300 with a PT1/4 (1/4 in) port, uses the standard 40 um filter element and a differential-pressure drain on the filter bowl, and regulates between 0.15 and 0.9 MPa (20-130 psi). A round gauge scaled in psi is fitted, a reverse/check valve is installed, and the mounting bracket is included. The filter and lubricator bowls are polycarbonate (PC). Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options include automatic or manual drains, a 5 um filter element (code W), G (BSPP) or NPT threads, and gauge scales in MPa, psi or bar. Flow figures are published as curves rather than a single rating, so ask us to confirm the datasheet 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 filtered, regulated and lubricated air to spray guns and air bells on a paint line, where water and particulate must be removed before the air reaches the finish.
Conditioning the air that drives pneumatic cylinders and grippers on a bottling or packaging conveyor, with the regulator holding a stable set point as actuators cycle.
Supplying cleaned, pressure-controlled and lubricated air to clamps and tool-change cylinders on a CNC machining cell, with the fitted check valve in the circuit.
The real choices in this series are the size and port step (200/300/400/600, 1/8 in to 1 in), matched to the flow your line needs; the drain type on the filter bowl (differential-pressure as here, automatic, or manual); the filter grade (40 um standard or 5 um with code W); the gauge and its scale (MPa, psi or bar); the thread (PT standard, with G and NPT as order options); and the reverse/check valve. Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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 number here. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing from the datasheet on request.
The GC combines a separate filter, regulator and lubricator, so each element can be serviced or replaced on its own. This GC30008C2K adds a round gauge scaled in psi and a reverse/check valve to the standard configuration of 40 um filtration, differential-pressure drain, 0.15-0.9 MPa (20-130 psi) regulation and a PT1/4 port.
