The AirTAC GFR600C25MLJNWT 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 GFR600C25MLJNWT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This size 600 unit is built with a 1 in NPT port, a 5 um filter element (code W, against the 40 um standard) and a manual drain on the aluminium alloy bowl that is standard at this size. Regulation is the low-pressure type, and no gauge, reverse/check valve or mounting bracket is fitted on this configuration. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
It is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in up to 1 in, and can be ordered with a different drain type, the 40 um standard element, a gauge, a reverse/check valve, a bracket, and PT (the standard thread) or G as alternatives to NPT. Flow is published by AirTAC as curves rather than a single rated figure, so ask us to confirm sizing and any datasheet figure against 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.

Feeds filtered, pressure-reduced air to spray guns on a finishing line where coatings call for a lower working pressure than a standard regulator set-point, with the 5 um element keeping fine particulate out of the finish.
Supplies cleaned, low-pressure air to sealing jaws and hold-down cylinders on a carton-forming line, filtering water and debris before it reaches the jets and valves.
Regulates and filters the low-pressure jet air on weaving machines where gentle, stable pressure matters more than a high set-point, and clean air protects the fine nozzles.
Choose the size and port step against the flow your line needs; this is the largest step, size 600 with a 1 in NPT port. The 5 um element (W) suits points of use that need finer water and particulate removal than the 40 um standard, and the manual drain (M) means someone opens the drain by hand on a routine, while automatic and differential-pressure drains are available on other variants. No gauge is fitted, so add a local gauge if the set-point must be watched. Regulation is the low-pressure type; the exact range is not published, so confirm it with us before relying on a set-point. Thread is NPT here, with PT as the standard and G also orderable. Flow is published as curves, not a single rating, so ask us to confirm sizing against the 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 rather than a single rated figure, so there is no one rated-flow number we can quote for the GFR600C25MLJNWT. Send us your line pressure, set-point and air demand and we will confirm sizing from the datasheet on request.
The M in the code is the drain: someone opens the drain by hand at routine intervals to clear collected water, instead of relying on an automatic or differential-pressure drain. If nobody will be on hand to drain the bowl, ask us about the automatic-drain variant of the same unit.
