The AirTAC GFR600C25MJF1TK AirTAC Filter Regulator NPT1 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 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 GFR600C25MJF1TK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation in a single body. This size 600 unit has a 1 in NPT port, a manual drain on the aluminium alloy bowl, and the standard 40 um filter element. The standard regulator covers 0.05-0.9 MPa (7-130 psi) with the embedded square MPa gauge fitted, a reverse/check valve is included, and no mounting bracket is supplied. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, plus automatic, manual or differential-pressure drains and an optional 5 um element (code W) where finer filtration is needed. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures 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.

Filtering and regulating the shop-air feed to a CNC machining centre's pneumatic clamps and tool-change cylinders, with the 1 in NPT port suiting a high-demand main drop.
Conditioning the compressed air feeding a paint-line booth, where the 40 um element strips water and pipe scale and the regulator holds a steady setting at the guns.
Supplying regulated air to the cylinders and actuators on a carton-sealing conveyor, with the reverse/check valve holding the downstream circuit if supply dips.
Within the GFR range you step up through sizes 200, 300, 400 and 600 - each step brings a larger port (1/8 in to 1 in) and more flow capacity, so match the size to the air demand of the machine rather than the pipe alone. Drain choice matters: manual means you bleed the bowl by hand, while automatic and differential-pressure drains handle condensate for you. The standard element is 40 um; specify code W for 5 um where finer filtration is required. Gauges come embedded square as standard with an external round gauge optional in MPa, psi or bar scales, and PT is the standard thread with G and NPT as order options. Flow is published as curves, not a single rated figure, so 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for the GFR600C25MJF1TK on request.
The M in the code means the aluminium alloy bowl is drained by hand - you open the drain to bleed off collected condensate. If you prefer unattended drainage, the same size is available with an automatic or differential-pressure drain; ask us for the matching code.
