The AirTAC GFR600C25ALNWT AirTAC Filter Regulator 1 in NPT 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 GFR600C25ALNWT is a 600-size filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built around a 1 in NPT port for high-flow lines, a 5 um filter element (code W) for finer filtration than the standard 40 um grade, and an automatic drain that expels collected condensate from the bowl without daily manual attention. It is the low-pressure regulator type, and no pressure gauge is fitted (code N). The maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C, non-freezing. At size 600 the bowl is aluminium alloy.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600, with a choice of port sizes, PT (standard), G or NPT threads, differential-pressure, automatic or manual drains, 40 um or 5 um filtration, gauge options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding clean, regulated low-pressure air to pneumatic clamps on a machining or assembly fixture, where the 5 um element keeps water and fine particles out of the clamp cylinders and the regulator holds a steady setting across the shift.
Conditioning the air line ahead of spray or coating guns in a finishing booth: the filter stage strips condensate and 5 um particulate before the gun while the low-pressure regulator holds a stable, gentle setting for a consistent finish.
Supplying filtered, regulated pilot air to pneumatically actuated process valves, where a stable low-pressure setting and clean, dry air keep valve positioning predictable and protect the pilot internals.
Start with the port and size step: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so match it to lines where the 200/300/400 sizes would restrict flow. The 5 um element (code W) suits downstream equipment that needs finer filtration than the standard 40 um grade; choose 40 um where general protection is enough. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are the alternatives on other configurations. This unit has no gauge fitted; gauge variants with square or round dials and MPa, psi or bar scales exist in the family. PT is the standard thread, with G and NPT as orderable options, and a mounting bracket is included with this unit. Note this is the low-pressure regulator type; its exact adjustment range is not published in the material we hold, so confirm it with us. 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, not as a single rated figure, so we do not state a flow number for this unit. Send us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet on request before you order.
This configuration carries gauge code N, so no pressure gauge is fitted; gauge variants with square or round dials in MPa, psi or bar scales are available elsewhere in the GFR range if you want a local reading. The automatic drain expels collected condensate from the aluminium alloy bowl on its own, so the unit does not need routine manual draining; specific drainage capacity figures are not published, and we can confirm datasheet details on request.
