The AirTAC GFR600C20ALC2TK AirTAC Filter Regulator NPT 3/4 in is a genuine G-series filter regulator: water separation, 40 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has See datasheet ports, a differential-pressure drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR600C20ALC2TK is a size-600 GFR filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 3/4 in NPT port, an automatic drain that expels collected condensate without manual attention, the standard 40 um filter element, and the low-pressure regulator type for circuits that run below standard regulated pressures. It is fitted with an external round gauge reading in psi and a reverse/check valve, and the size-600 bowl is aluminium alloy. A mounting bracket is included.
This is a genuine AirTAC part. The GFR line is offered in sizes 200, 300, 400 and 600 with a choice of port, thread (PT standard, G and NPT as options), drain type, filter grade (40 um standard, 5 um optional), gauge style and scale, and low-pressure or standard regulator type. Flow is published as curves rather than a single rating, so we confirm flow and datasheet 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). Air must not freeze in the unit. 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, bracket, gauge, shape, scale, grade, thread, reflux — a blank position takes the default. Example: GFR300-08 is a 300 body, PT1/4", differential drain, standard type, bracket included, gauge fitted, 40 µm, PT thread, no reflux valve.
A larger body carries a larger port and holds set pressure better as flow rises. AirTAC publishes flow only as curves, so size the body from your peak demand with headroom. The GFR600 uses an aluminium-alloy bowl; the 200, 300 and 400 bodies use PC.

Feeds the clamp-and-unclamp circuit of a machining centre, filtering carryover water and pipe scale from the shop air while holding the reduced pressure the clamp cylinders were specified for.
Sits at the drop point feeding diverters, pushers and sealing jaws on a packaging conveyor, keeping condensate out of the valves and delivering steady regulated air shift after shift.
Supplies air knives and blow-off nozzles that dry bottles before labelling, removing moisture from the supply and letting operators set the gentle reduced pressure delicate containers need.
Start by matching the size and port to the air demand of the circuit: the GFR series steps through sizes 200, 300, 400 and 600, with this unit at size 600 on a 3/4 in NPT port for the largest duty in the range. Choose the drain to suit access: automatic (this unit) for unattended condensate removal, manual where you want controlled purging, or the differential-pressure default. Pick the filter grade - 40 um standard or the 5 um W option where finer particulate protection is needed - and the gauge style and scale (this unit carries a round gauge in psi; embedded square gauges and MPa/bar scales are the other catalogue choices). Thread is PT as standard with G and NPT orderable, and a bracket is included on this configuration. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for the GFR series as curves rather than a single rated figure, so we do not quote a flow number. Tell us your application and we will confirm the flow and datasheet figures for this unit on request before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the bowl without anyone opening it - the right choice for unattended or hard-to-reach installations. The catalogue alternatives are manual drain, where an operator purges the bowl, and the differential-pressure drain that is the default on units without a drain letter. All three are orderable across the GFR range.
