The AirTAC GC600-20 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 GC600-20 is a three-piece F.R.L. combination that conditions compressed air in one assembly: a filter that removes water and particulate, a pressure regulator, and an oil-mist lubricator. This size 600 configuration is built around a 3/4 inch PT port. The filter element is the standard 40 um grade, the bowl drains automatically, and because this is the 600 size the bowls are aluminium alloy. The regulator is the standard type with an adjustment range of 0.15-0.9 MPa (20-130 psi) and a fitted round gauge reading in psi, and a reverse/check valve is fitted. The maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GC combination is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 inch up to 1 inch, and with choices of drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, thread (PT standard, with G and NPT as catalogue options) and bracket. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and flow 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.

Feeds clean, regulated and lubricated air to the tool-clamp and pallet-change circuits of a CNC machining centre, protecting valves and cylinders from water and swarf-laden shop air.
Installed at the line drop serving air-driven paint agitators and spray-gun air feeds, where filtered, pressure-stabilised and lightly oiled air supports consistent finish work.
Conditions the air feeding pneumatic pushers, diverters and clamp cylinders on a packaging and palletising conveyor, keeping the actuators running smoothly through long shifts.
Start with the port and size step: this unit is size 600 with a 3/4 inch PT port, the largest step in the range, so match it against the air demand of the circuit - and ask us to confirm sizing, because flow is published as curves rather than a single rating. The drain here is automatic, which suits unattended installations; manual and differential-pressure drain versions exist if you prefer scheduled or load-dependent draining. The filter grade is the standard 40 um; a 5 um element (code W) is available where downstream equipment needs finer filtration. The gauge is a round external type scaled in psi; embedded square gauges and MPa or bar scales are the other catalogue choices. Thread is PT as standard, with G (BSPP) and NPT available to order, and 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 the GC series as curves rather than a single rated figure, so we do not quote a rated flow, Cv or SCFM number. Tell us your application and operating pressure and we will confirm the flow and datasheet figures for this model on request before you order.
The A in the code means the filter bowl drains automatically, so collected condensate is discharged without manual intervention - useful for units mounted out of easy reach or on lines that run unattended. The trailing K means a reverse/check valve is fitted, and the C2 indicates the round gauge scaled in psi.
