The AirTAC GC600-20ALF2K AirTAC F.R.L. Combination, PT3/4 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 40 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC600-20ALF2K is a three-unit F.R.L. combination: a separate air filter, pressure regulator and oil-mist lubricator assembled as one supply package. This size-600 configuration carries a 3/4 in PT port, a 40 um filter element with automatic drain, aluminium alloy bowls, a low-pressure type regulator with an embedded square gauge scaled in psi, a fitted reverse/check valve, and a mounting bracket. It treats the compressed air line in one pass: water and particulate are removed, downstream pressure is set on the gauge, and a fine oil mist is carried to the connected pneumatic equipment.
This is a genuine AirTAC part. The GC series spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and options including manual or differential-pressure drains, a 5 um filter element (code W), gauge scale in MPa, psi or bar, and G (BSPP) or NPT threads in place of the PT standard. Published flow data appears as curves rather than a single rating, so we confirm the figures from the datasheet 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. 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 filtered, regulated and lubricated air to the tool-change clamps, pneumatic chucks and coolant-valve actuators on a machining centre, with the 3/4 in port serving the machine's main drop.
Supplies the carton-forming, sealing and case-packing cylinders on a packaging line, keeping moisture out of the valves and metering oil mist to the cylinders that cycle all shift.
Conditions the air feeding spray-booth air tools and conveyor spurs in a paint shop, where the automatic-drain bowl and 40 um element protect downstream equipment from water and debris.
Start with the size and port: the 600 frame with its 3/4 in PT port sits at the top of the GC range, so match it against the air demand of the line before ordering - flow is published as curves, not a single rating, so ask us to confirm sizing against your application. Choose the drain to suit the installation: automatic (as fitted here) empties the bowl without operator attention, manual suits attended stations, and differential-pressure drain is the catalogue default. The 40 um element is standard; specify the W code if the application needs 5 um filtration. The square gauge is scaled in psi here, with MPa or bar available, and an external round gauge is optional. PT is the standard thread; G (BSPP) and NPT are order options. A bracket is included with this unit.
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, not as a single rated figure, so we do not quote a number here. Ask us and we will confirm the flow data from the datasheet against your application before you order.
The GC is a three-piece combination - separate filter, regulator and lubricator - so each element is serviced on its own; a two-unit set such as the GFC omits the standalone lubricator. The automatic drain fitted to this unit's filter bowl expels collected condensate by itself, so the bowl does not need manual draining during operation.
