The AirTAC GC600-20 AirTAC F.R.L. Combination, PT3/4, 5 um Filter 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 GC600-20 is an AirTAC GC-series three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one set. This configuration is the size 600 unit with a 3/4 in PT port, the 5 um filter element (code W) for finer water and particulate removal than the standard 40 um grade, an automatic drain on the filter bowl, and a round external pressure gauge with a psi scale. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi), maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing). At size 600 the filter bowl is aluminium alloy.
This is a genuine AirTAC part. The GC family is offered in sizes 200, 300, 400 and 600 with matching port sizes, and options include the 40 um standard or 5 um (W) filter grade, differential-pressure, automatic or manual draining, gauge choice and scale (MPa, psi or bar), and G (BSPP) or NPT threads in place of the PT standard. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet figures 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. 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.

At a 3/4 in main drop feeding paint booths, the 5 um element and regulator deliver cleaned, pressure-controlled air to spray equipment, while the lubricator mists oil for downstream air tools.
On a cartoning or case-packing conveyor line, this F.R.L. set conditions the plant air feeding pneumatic cylinders and grippers, holding a stable set pressure and lubricating the actuators.
For a workshop pneumatic press or clamping cell on a 3/4 in supply, the combination filters water and particles from the compressed air, regulates working pressure, and oils the air circuit.
Start with the port and size step: this is the size 600 unit with a 3/4 in PT port, the largest step in the GC range (200/300/400/600), so size up or down against the air demand of the line. The 5 um (W) element suits points of use that need finer filtration than the 40 um standard; the automatic drain on this unit evacuates condensate without manual attention, while manual and differential-pressure drains remain available in the family. The regulator is the standard type, adjustable 0.15-0.9 MPa (20-130 psi), and the gauge on this configuration is the external round type with a psi scale; square embedded gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT as order options, and a mounting bracket is included.
One honest note on sizing: flow for this series is published as curves, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the sizing and datasheet figures before you order.
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 state a number here. Send us your application details and we will confirm the flow and datasheet figures for this 3/4 in, size 600 unit on request.
This GC600-20 is ordered with the automatic drain (code A), which discharges condensate from the filter bowl without operator attention. The catalogue also offers manual draining (code M) and the differential-pressure drain as the default, so you can choose the drain type that matches how the unit is maintained.
