The AirTAC GC600-20G AirTAC F.R.L. Combination, G3/4, 5 um 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 PT3/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The GC600-20G is an AirTAC size 600 three-piece F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator, assembled as one set. This configuration is built around a G3/4 (3/4 in) port with G thread, a 5 um filter element, an automatic drain on the filter bowl, and a fitted square gauge reading in psi. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), and the unit carries a maximum inlet pressure of 1.0 MPa (145 psi) over a working temperature range of -5 to 70 C (non-freezing). At size 600, the filter bowl is aluminium alloy.
This is a genuine AirTAC part, sold by an authorised distributor. The GC series is available in sizes 200, 300, 400 and 600, with port options, drain types, filter grades (40 um standard, 5 um optional), gauge styles and scales, and thread variants (PT standard, with G and NPT as order options). Flow for this series is published as curves rather than a single rated figure, so contact us and we will confirm the datasheet 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: GF600-20 filter, GR600-20 regulator and GL600-20 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 machine shop can mount this F.R.L. at the drop feeding its CNC machining centre's pneumatic actuators and tool-clamp circuits, filtering machining-hall air to 5 um, holding a steady regulated pressure and delivering oil mist to the cylinders.
On a bottling or carton-packing line, this unit at the header feeding conveyor stop-gate and divertor cylinders keeps water and particles out of the valves, regulates supply pressure for consistent gate action, and lubricates the cylinders in continuous duty.
A metal stamping plant can install this combination at the supply to a press's clutch, counterbalance and part-blow-off circuits, where the 5 um grade protects the control valves, the regulator sets working pressure, and the lubricator services the air motors.
Size 600 with a G3/4 port is the largest step in the GC range, so start by matching it against the air consumption of the line it feeds - and because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering. The drain choice matters in practice: this unit has an automatic drain, which empties the bowl without operator attention; manual and differential-pressure drain versions exist if you prefer scheduled or load-dependent draining. The 5 um element (code W) is the finer option versus the 40 um standard, useful where downstream valves and cylinders need cleaner air.
Other decodable choices: the square gauge is fitted here reading psi, with MPa or bar scales and an external round gauge available as options; thread is G on this unit while PT is the standard and NPT can be ordered; and a mounting bracket is included. Set the regulator anywhere in its 0.15-0.9 MPa (20-130 psi) range and set the lubricator's oil-mist rate to suit the tools and cylinders downstream.
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 GR600-20 regulator with a GF600-20 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 rated flow number. Tell us your operating pressure and air demand and we will confirm the flow figures from the datasheet for this exact model on request before you order.
The A in the code GC60020AF2WG specifies an automatic drain, which expels collected condensate from the bowl without manual intervention; the W specifies the 5 um element instead of the 40 um standard. Both are order-time choices - manual and differential-pressure drains and the 40 um grade are available on other variants in the series.
