The AirTAC GFR600C25ALC3WTK AirTAC Filter Regulator NPT1 Low Pressure 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 GFR600 series combines water and particulate filtration with pressure regulation in a single body, and this GFR600C25ALC3WTK is the size 600, 1 inch NPT version. Filtration is the fine 5 um grade (code W) rather than the 40 um standard, an automatic drain expels collected condensate from the bowl without manual attention, and the regulator is the low-pressure type for circuits that run below standard line pressure. A round external gauge scaled in bar is fitted, a reverse (check) valve is built in, the size 600 bowl is aluminium alloy, and the mounting bracket is included. Maximum working 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 GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options include manual or differential-pressure drains, 40 um or 5 um elements, embedded square or external round gauges with MPa, psi or bar scales, G or NPT threads in place of the PT standard, and low-pressure regulation. Flow is published as curves rather than a single rating, so ask us to confirm sizing figures from the datasheet for your application.

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 conditioning for carton-forming and case-packer cylinders on a packaging line: the 5 um element protects directional valves from water and particulate while the low-pressure regulator holds a gentle working pressure for delicate clamp motions.
Feeding pilot valves, transducers and small control actuators on a process skid that runs at reduced pressure, where the automatic drain keeps condensate off the instruments without daily bowl checks.
Conditioning air to spray guns in an automotive refinish booth, where the 5 um filtration helps keep water and dirt out of the finish and the low-pressure regulator is trimmed to the gun's working pressure.
The real choices within GFR600 are the port size against the flow your line needs (here 1 inch NPT), the drain (differential-pressure standard, automatic or manual), the filter grade (40 um standard or 5 um with W), the gauge (embedded square as standard, external round optional, scaled in MPa, psi or bar), the thread (PT is the AirTAC standard; G and NPT are order options such as the NPT on this unit), the reverse/check valve, and whether a bracket is fitted. Regulation on this unit is the low-pressure type; its exact adjustment range is not published on the sheet we work from, so confirm it with us. Because flow is published as curves rather than a single rated figure, send us your application details and we will confirm sizing from 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 flow for the GFR series as curves, not as a single rated figure, so we do not quote a number here. Send us your line pressure, working pressure and expected air consumption and we will confirm the flow from the datasheet before you order.
The A in the code specifies an automatic drain, which expels collected condensate from the aluminium alloy bowl without manual attention. The GFR600 series is also available with a manual drain or the standard differential-pressure drain, and the filter grade can be the 40 um standard instead of the 5 um (W) fitted here - tell us which combination you need.
