The AirTAC AirTAC GC600-20G F.R.L. Combination Unit, G3/4 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 AirTAC GC600 is a three-piece F.R.L. air-treatment combination: a separate filter, pressure regulator and oil-mist lubricator built up as one coordinated set. This configuration is the size 600 unit with a G3/4 (3/4 inch) port in G (BSPP) thread. The filter section carries a 5 um element (code W) with an automatic drain, so collected water is expelled without manual attention, and the filter bowl is aluminium alloy, as is standard at size 600. The regulator is the low-pressure type and comes with an embedded square gauge scaled in psi; an external round gauge is available as an option. The lubricator delivers oil mist downstream to protect air tools and cylinders. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). A mounting bracket is included.
This is a genuine AirTAC part. The GC series is available in sizes 200, 300, 400 and 600, with port sizes from 1/8 inch to 1 inch, PT as the standard thread and G or NPT as order options, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um (W) filtration, gauge scale in MPa, psi or bar, and an optional reverse/check valve. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.

Feeds clean, regulated and lubricated air to the cylinders and grippers on a bottling or carton-packing line, with the 5 um element helping protect the directional valves that cycle throughout each shift.
Supplies the actuation circuit of a pneumatic press or clamping fixture, where the low-pressure regulator holds the working pressure the tooling was set up for and the lubricator keeps cylinder seals conditioned.
Prepares the air feeding diverters, gates and stoppers on a conveyor or sortation system, with the automatic drain clearing condensate so the valves are not exposed to accumulated water.
Start with the port step: size 600 with a G3/4 port suits lines running larger volumes of compressed air, while sizes 200 to 400 cover smaller ports down to 1/8 inch. Match the size to the flow your line needs - because flow is published as curves rather than one rated number, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type; its exact regulation range is not published, so confirm it with us if your set pressure is critical. The 5 um element (code W) is the finer choice over the 40 um standard where downstream valves and cylinders need cleaner air. The automatic drain handles condensate on its own; manual and differential-pressure drains are the alternatives in this family. The fitted square gauge is scaled in psi, with MPa or bar available as options. PT is the standard thread and G or NPT are order options - this code specifies G (BSPP). A 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 GR600-20 regulator with a GF600-20 filter on that branch.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a rated flow number. Tell us your line conditions and required flow and we will confirm the datasheet figures and check the sizing for your application on request.
The W code in the model specifies the 5 um element instead of the 40 um standard, giving finer removal of particulate ahead of the regulator and lubricator. The A code specifies an automatic drain, which expels collected condensate from the filter bowl by itself instead of waiting for a manual drain. Both are order choices within the GC series.
