The AirTAC GFR600-25 AirTAC Filter Regulator NPT1 (1 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 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 GFR600-25 is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit is specified with a 1 in NPT port, the standard 40 um filter element, and an automatic drain that expels collected condensate without manual attention. It is supplied without a gauge, so add a separate gauge if you need a local pressure readout at the unit.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drains, an optional 5 um element (code W), and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi). Flow is published as curves rather than a single rating, so ask us to confirm 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.

Installed at the take-off from a large compressed-air ring main, the GFR600-25 filters condensed water and pipe scale from the 1 in supply line and holds a steady regulated pressure for the downstream distribution legs.
Feeding a conveyor line's pneumatic diverters, stoppers and lift cylinders, the unit cleans the incoming air with its 40 um element and keeps actuator pressure consistent, while the automatic drain handles condensate without daily checks.
Mounted inside a machine tool's air preparation panel, the GFR600-25 combines filtration and regulation in one body to save panel space, supplying clean, regulated air to clamps, tool-change cylinders and air blast nozzles.
For this GFR600-25, the size-600 body with the 1 in port is the step to choose when your line flow and piping are at the top of the range; smaller GFR sizes (200/300/400) cover lighter duties with 1/8 to 3/4 in ports. The 40 um element is the standard grade for general plant air; specify the 5 um W variant if downstream equipment needs finer filtration. The automatic drain suits unattended or hard-to-reach installations, while manual and differential-pressure drains are the alternatives. Thread here is NPT, with PT and G available to order, and a bracket is included for panel or wall mounting. 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 GFR series as curves, not as a single rated figure, so we do not quote a number. Tell us your line pressure and required flow and we will confirm the sizing from the datasheet on request before you order.
This configuration carries the N gauge code, so no pressure gauge is fitted; a separate gauge can be added if you need a local readout. The A in the code is the automatic drain, which discharges collected condensate from the aluminium alloy bowl on its own, so the unit suits installations that are not checked daily.
