The AirTAC GFR600C25MJF3WTK 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 GFR600C25MJF3WTK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This size 600 unit is threaded NPT1 (1 in), carries the fine 5 um filter element (code W, versus the 40 um standard), a manual drain on the aluminium alloy bowl, an embedded square gauge scaled in bar, and a reverse (check) valve fitted. It is a standard-type regulator handling compressed air at up to 1.0 MPa (145 psi) inlet, with an adjustment range of 0.05-0.9 MPa (7-130 psi) and an operating temperature of -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 in to 1 in, and offers drain choices (differential-pressure, automatic or manual), 40 um or 5 um filtration, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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.

Filter and regulate the air feeding spray guns and air-assisted applicators in a paint booth. The 5 um element keeps particulates out of the finish, the regulator holds a steady set pressure at the gun, and the manual drain is emptied at shift start.
Point-of-use conditioning for individual CNC machining centres and their pneumatic clamps and tool-change circuits: one 1 in NPT filter regulator per large drop, with the bar-scale gauge giving operators a local pressure check.
Supply filtered, regulated air to conveyor diverters, carton sealers and case packers on a high-volume packaging line. The reverse/check valve holds the downstream circuit if upstream supply dips, and the manual drain suits a scheduled maintenance round.
Size and port set the capacity: this is the largest GFR size, 600, with a 1 in NPT port, so match the size step to the flow your line needs. The choices decoded into this code are all real options you can vary: manual drain (drained by hand - automatic or differential-pressure drains suit units you cannot easily access), 5 um filtration instead of the 40 um standard, a bar-scale square gauge (MPa or psi scales are also available), and the fitted reverse/check valve. The J code means no mounting bracket is included. Thread here is NPT; PT is the AirTAC standard and G (BSPP) can also be ordered as a specification option. Because flow is published as curves rather than a single rated figure, 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 there is no one l/min or SCFM number we can honestly quote. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The M code means condensate in the aluminium alloy bowl is drained by hand rather than automatically. Choose manual drain where the unit is easily accessible and checked on a routine round; if the unit sits where it cannot be reached regularly, the automatic (A) or differential-pressure (blank) drain options are the better decode.
