The AirTAC GC600-20 AirTAC F.R.L. Combination Unit, 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 PT3/4" ports, a 5 µm element, a automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi).
The AirTAC GC600-20 is a three-piece F.R.L. combination that filters, regulates and lubricates compressed air in one assembled set: a separate filter with 5 um element and automatic drain, a pressure regulator with a fitted round psi gauge, and an oil-mist lubricator. The G3/4 (BSPP) port suits larger plant air drops, the maximum inlet pressure is 1.0 MPa (145 psi), the regulator adjustment range on this automatic-drain set is 0.15-0.9 MPa (20-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). The bowls on this size 600 unit are aluminium alloy, and a reverse/check valve is fitted (code K) with the mounting bracket included.
This is a genuine AirTAC part. The GC family is available in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as order options), drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, and reverse/check valve. Flow is published as curves rather than a single rating, so we confirm the datasheet and sizing figures 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.

Clean, regulated and lubricated air for tool changers, clamps and pneumatic actuators on a machining centre fed from a 3/4 in plant air drop, with the 5 um element protecting fine-control valves.
Conditioning the air feed to impact wrenches and air ratchets at assembly stations: the regulator holds a stable setting while the lubricator carries oil mist to the tools.
Feeding the valve manifold and cylinders of a palletising or case-packing cell, where the automatic drain keeps condensate off the valves and the check valve holds the circuit on air loss.
Start with the size and port: 200/300/400/600 step up in port and flow capacity, so match the size to the air demand of the downstream circuit - here the 600 size with G3/4 ports is the largest step. Choose the drain type: automatic (this unit) drains the filter bowl without attention, manual needs operator action, and the default is differential-pressure. Choose the filter grade: 40 um is standard for general plant air, 5 um (code W, fitted here) for finer protection. Pick the gauge style and scale (embedded square standard, external round optional; MPa, psi or bar), the thread (PT standard, G or NPT to order), and whether a bracket or reverse/check valve is wanted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 family as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Tell us your application and we will confirm the flow and sizing from the datasheet on request.
The code W in GC60020AC2WGK selects the 5 um element instead of the 40 um standard, for finer protection of downstream valves and cylinders. The code A selects the automatic drain, which expels collected condensate from the filter bowl without manual attention.
