The AirTAC GC600C20ALF2WGK AirTAC F.R.L. Combination, G3/4 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 See datasheet ports, a 40 µm element, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600C20ALF2WGK is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one 600-size set. This configuration is built around a G3/4 (3/4 in) port, 5 um filtration (the finer of the two catalogue grades), an automatic drain on the filter bowl, a low-pressure type regulator with an embedded square gauge scaled in psi, and a reverse/check valve fitted. The aluminium alloy bowls used at the 600 size suit installations where a polycarbonate bowl would not be the first choice, and the set includes a mounting bracket.
This is a genuine AirTAC part supplied by airdistribution partner airtacdistr.com for the US market. The GC series is available in 200, 300, 400 and 600 sizes with a choice of port, drain type, filter grade (40 um standard, 5 um optional), gauge scale (MPa, psi or bar) and thread (PT standard; G and NPT are order options). Max working inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Installed at the take-off point of a factory compressed-air ring main, the filter strips water and 5 um particulate, the regulator holds a steady low working pressure for the downstream circuit, and the lubricator feeds oil mist to the air tools and cylinders on that leg.
On a bottling or cartoning line with dozens of pneumatic actuators, this three-unit set conditions the whole header supply: clean, dry, regulated air with consistent lubrication keeps the cylinders and stopper gates running shift after shift, and the automatic drain empties the bowl without an operator visit.
Fitted ahead of a machining centre's pneumatic panel, the combination protects clamps, tool-change cylinders and air chucks: fine 5 um filtration guards the valves, the low-pressure regulator matches the circuit's modest working pressure, and the check valve helps hold the downstream circuit if supply pressure dips.
The 600 size with its 3/4 in port sits at the top of the GC range, so step up or down (200/300/400/600) according to the flow your line needs - and because flow is published as curves, not a single rating, ask us to confirm sizing against your application before ordering. This unit already carries the finer 5 um grade (code W) instead of the 40 um standard, an automatic drain instead of manual or differential-pressure, and a psi-scaled square gauge; the external round gauge and MPa or bar scales are alternatives you can order. Thread is G here, with PT as the standard and NPT available as an order option. The low-pressure type regulator is the right choice where your working pressure stays well below the standard regulator's range; its exact adjustment range is not published, so confirm it with us. A reverse/check valve is fitted and the mounting bracket is included.
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 figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and we will confirm the flow figures from the datasheet on request, and help you check whether the 600 size is the right step against the 200/300/400 sizes.
The automatic drain (code A) expels collected condensate from the filter bowl on its own, so no manual draining round is needed. The 5 um element (code W) is the finer of the two catalogue grades, the standard being 40 um, so it suits circuits with more sensitive valves and cylinders. Both are fixed in this code; the alternative drain types (manual, differential-pressure) and the 40 um grade are available in other GC order codes.
