The AirTAC GFR600-25T AirTAC Filter Regulator 1 in NPT 5 um Auto Drain is a genuine G-series filter regulator: water separation, 5 µm particulate filtration and balanced-type pressure regulation combined in a single body. It has PT1" ports, a automatic 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 GFR600-25T combines water and particulate filtration with pressure regulation in a single body, sized at 1 in NPT for high-flow compressed-air lines. This configuration carries the 5 um filter element (code W) for finer contaminant removal than the standard 40 um grade, an automatic drain that expels collected condensate without manual attention, and an embedded square gauge reading in MPa so the set pressure is visible at a glance. The maximum working pressure is 1.0 MPa (145 psi) and the regulator adjusts across 0.15-0.9 MPa (20-130 psi).
This is a genuine AirTAC part from the GFR600 series, the largest size in the GFR line (sizes 200/300/400/600). At size 600 the bowl is aluminium alloy, and a mounting bracket is included. Operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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.

Feeding filtered, regulated air to the pneumatic tool circuits and clamping fixtures of a CNC machining centre, where the 5 um element protects spools and seals from fine particulate and the automatic drain keeps condensate off the shop floor.
Supplying regulated air to the grippers, diverters and pusher cylinders on a bottling or packaging line, with the 1 in port serving the main header and the square gauge letting technicians verify set pressure during changeover.
Conditioning supply air for quarter-turn pneumatic valve actuators on a process skid, where the automatic drain handles moisture in a remote installation and the regulator holds a stable set point for consistent actuator stroking.
Step up to size 600 with a 1 in port when the line's required flow exceeds what a 1/2 in or 3/4 in unit can pass; the GFR600 is the top of the GFR size range. Choose the 5 um element (this unit, code W) when downstream valves, cylinders or instruments need finer protection than the standard 40 um grade. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are available in the family if you prefer to control discharge. The embedded square gauge reads MPa; psi and bar scales and an external round gauge can be ordered. NPT thread is specified here; G (BSPP) and PT are catalogue options. A mounting bracket is included.
Because flow is published as curves rather than a single rating, 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 flow for the GFR600 series as curves, not as a single rated number, so we do not quote a figure. Send us your line pressure and required flow and we will confirm the sizing against the datasheet on request before you order.
Code A in GFR60025AF1WT specifies the automatic drain, which discharges collected condensate on its own - useful for unattended or elevated installations. The GFR family also offers manual and differential-pressure drains as orderable alternatives if your maintenance routine prefers them.
