The AirTAC GFR600C25MLF3WT 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 GFR600C25MLF3WT is a size-600 filter regulator: it removes water and particulate from compressed air and holds a reduced downstream pressure in one body. This configuration is built for a 1 in NPT port, carries the 5 um filter element (code W), drains by hand through the manual drain, and is the low-pressure regulator type. The embedded square gauge is fitted with a bar scale, the 600-size bowl is aluminium alloy, and the mounting bracket is included. 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, and each unit can be ordered with a different drain type, filter grade, gauge scale, thread (PT standard, G or NPT as options) and bracket arrangement. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

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 filtered, pressure-reduced air to spray guns in a finishing booth, where the low-pressure regulator type holds a stable reduced setting and the 5 um element keeps water and particulate out of the atomizing circuit.
Conditioning the air supply to a laboratory or pilot-scale process skid: the filter stage strips condensate and dirt before the instruments and pneumatic controls, and the regulator holds the reduced pressure the skid is set up for.
Supplying the clamp and flap cylinders on a packaging conveyor's carton sealer, where filtered air protects the cylinders and the regulator holds the reduced working pressure the clamp mechanism was designed around.
Start with the size and port: the 600 frame with its 1 in connection suits lines whose supply piping and air demand sit at the top of the G-series range, while 200/300/400 units step down for smaller ports. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Next, choose the drain: this unit has the manual drain, where the bowl is bled by hand on a maintenance round; automatic and differential-pressure drains are available if you would rather not rely on an operator. The filter grade here is 5 um; the 40 um standard element is the alternative where finer filtration is not needed. The fitted square gauge reads in bar, and MPa or psi scales can be ordered instead. Thread is NPT on this code; PT is the standard and G is also a catalogue option. The bracket is included.
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 number, so there is no honest one-line figure to quote. Tell us your line pressure and the air demand of the equipment downstream, and we will confirm the sizing from the datasheet curves on request before you order.
The M in the code selects the manual drain: the bowl is bled by hand as part of a maintenance round, which suits installations that are visited regularly. If you would rather not rely on an operator, the same 600-size filter regulator can be ordered with an automatic drain or with the differential-pressure drain, which is the default.
