The AirTAC GC600C25ALC2GK AirTAC F.R.L. Combination G1 Low-Pressure 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 GC600C25ALC2GK is an AirTAC GC three-unit F.R.L. combination: a separate filter, regulator and lubricator assembled as one set, doing three jobs on the same compressed-air line - removing water and particulate, holding a set downstream pressure, and adding oil mist for downstream air tools and cylinders. This configuration is built around a G1 (1 in) port, the largest size in the range, for high-demand supply lines. The filter carries the standard 40 um element with an automatic drain, so collected condensate is expelled without anyone opening the bowl. The regulator is the low-pressure type and is fitted with an external round gauge reading in psi; a reverse/check valve is also fitted, and the mounting bracket is included. At size 600 the filter bowl is aluminium alloy.
This is a genuine AirTAC part. The GC series is offered in sizes 200, 300, 400 and 600 with matching ports, and can be ordered with manual or automatic or differential-pressure drains, a 5 um (W) filter element instead of the standard 40 um, standard or low-pressure regulation, gauge or no gauge, different gauge scales, a reverse/check valve, and G or NPT thread instead of the PT standard. Flow is published as curves rather than a single rating, so we confirm the datasheet and flow figures 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.

Feeding a bottling hall's ring main, where the F.R.L. set cleans water and debris from the compressed air, holds a steady low-pressure supply for the filler actuators, and lubricates the cylinders running thousands of cycles per shift.
Supplying the air cylinders that lift, stop and divert cartons on a distribution conveyor line, giving them filtered, pressure-stabilised and lubricated air so seals and moving parts last in continuous duty.
Serving the drop lines at machining centres and presses, where the set removes condensate from a humid compressor room supply, regulates pressure for clamping fixtures, and mists oil to the impact tools and air chucks at each station.
Start with the port step: sizes 200, 300, 400 and 600 map to 1/8 in through 1 in ports, and the 600 size with its G1 (1 in) port suits the largest supply lines - but the right step depends on the flow your line actually needs. Next choose the drain: automatic (as here) empties the filter bowl on its own, manual needs an operator, and the differential-pressure default discharges when the pressure drop across the element rises. Filter grade is 40 um standard or 5 um (W) where finer filtration is wanted. The gauge can be the embedded square type or an external round gauge, with MPa, psi or bar scales - this unit has a round psi gauge. Thread is PT as standard, with G (BSPP) and NPT as order options; brackets are included on this set. Because flow is published as curves rather than a single rated figure, ask us to confirm sizing against your application before ordering.
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 this series as curves, not as a single rated number, so there is no one figure we can honestly quote. Tell us your line pressure and the flow your equipment needs, and we will confirm the sizing from the datasheet on request before you order.
The L in the code marks the low-pressure regulator type, intended where the downstream equipment needs a lower working pressure than a standard regulator is aimed at. The exact adjustment range for this low-pressure variant is not published in the material we hold, so we confirm it on request; the standard-range figures apply to the non-L versions of the series.
