The AirTAC GFR600C20ALC1TK AirTAC Filter Regulator NPT3/4 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 GFR600C20ALC1TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with 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. A round MPa pressure gauge is fitted, a reverse/check valve is included, and the unit ships with its mounting bracket. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part in the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, a 5 um optional element (code W), gauge scale choices, and G, NPT or PT threads. Flow figures 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). 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.

Point-of-use clean-up and pressure setting for the air feeding tool clamps, pneumatic actuators and coolant blow-off on a machining centre, with the automatic drain handling condensate between shifts.
Conditioning the air that drives carton-forming and case-sealing cylinders on a packaging line, where the low-pressure regulator type sets a modest working pressure and the 40 um element keeps debris out of valves.
Filtered, regulated air for pop-up divertors, stops and gate cylinders along a conveyor system, with the check valve holding the set circuit and the automatic drain keeping the bowl clear without operator rounds.
Start with the port step: size 600 carries a 3/4 in port, and the GFR range steps through 200/300/400/600 as flow demand rises - match the size to the air consumption of the circuit rather than the pipe alone. Choose the drain to suit attendance: automatic (this model) suits unattended duty, manual suits periodic checks, differential-pressure drain is the catalogue default. Filter grade is 40 um standard; specify 5 um (code W) where finer particulate removal is needed. Gauge scale is selectable (MPa, psi or bar), and this unit carries the round gauge with MPa scale. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. Bracket is included on this model.
Flow for the GFR series is published as curves, not a single rated figure, so we cannot quote one number here. Send us your application details and we will confirm sizing against the datasheet before you order.
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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your application - port size, downstream consumption and working pressure - and we will confirm the flow and datasheet figures for this unit on request before you order.
The A in the code specifies the automatic drain, which expels collected condensate from the bowl without manual attention - useful where the unit is mounted away from daily operator rounds. The GFR series is also available with a manual drain or the differential-pressure drain (the catalogue default); tell us which suits your installation and we will confirm the matching model.
