The AirTAC GC600C25ALF2G AirTAC F.R.L. Combination Unit, G1 (1 in) 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC series is a three-piece F.R.L. combination: a separate air filter, a pressure regulator and an oil-mist lubricator assembled as one air-treatment set. This GC600C25ALF2G is the size 600 unit with a G1 (1 in) G-thread port, built for the largest port and flow step in the range. The filter section carries the standard 40 um element with an automatic drain, so collected condensate is discharged without manual attention. The regulator is the low-pressure type and is fitted with an embedded square gauge scaled in psi; an external round gauge is available as an option. The bowls on the size 600 filter and lubricator are aluminium alloy, and the unit includes a mounting bracket. A reverse/check valve is not fitted. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination is offered across sizes 200, 300, 400 and 600, with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, a 5 um filter element (code W) in place of the standard 40 um, gauge scale choices of MPa, psi or bar, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rated number, 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: GF600-C2 filter, GR600-C2 regulator and GL600-C2 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 spray-booth and air-balance circuit on a paint line, where the automatic drain handles condensate from a high-volume 1 in main without daily manual blowing down.
Supplies the pneumatic cylinders and air-actuated gates along a bottling or canning conveyor, giving the line one point where water and particles are removed, pressure is set and cylinder air carries a fine oil mist.
Serves the air drops feeding looms and winding machines, where the low-pressure regulator holds a gentle supply setting for sensitive mechanisms and the lubricator keeps air motors and cylinders running smoothly.
Start with the port and size step: the GC series steps through sizes 200, 300, 400 and 600, and this unit sits at the top with a G1 (1 in) port, so match the size step against the air demand of the line rather than the pipe thread alone. Because flow for this series is published as curves and not as a single rated figure, ask us to confirm sizing against your application before ordering. Next choose the drain: this configuration has an automatic drain, which discharges condensate on its own; manual and differential-pressure drain versions are also available in the family. The filter grade here is the standard 40 um element; if downstream equipment needs finer filtration, the 5 um element (code W) is the alternative. The regulator in this unit is the low-pressure type, so confirm the low-pressure range suits your circuit. The fitted square gauge is scaled in psi; MPa and bar scales are the other options, and an external round gauge can be ordered instead. Thread is G (BSPP) on this model; PT is the catalogue standard and NPT is also an order option. A mounting bracket is included; a reverse/check valve is not fitted on this code.
Quick checklist
The aluminium-alloy bowls on the GC600 suit harsher environments than PC bowls. 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 GR600-C2 regulator with a GF600-C2 filter on that branch.
AirTAC publishes flow for the GC series as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line demand and working pressure and we will confirm the datasheet and check this size 600, G1 (1 in) unit against your application before you order.
The A in the code GC600C25ALF2G means the filter bowl drains itself automatically, which suits unattended 1 in mains where condensate collects quickly. If you prefer to control drainage manually or to use the differential-pressure drain arrangement, those versions exist in the GC family and we can quote the matching code.
