The AirTAC GFR600C25MLJF2K AirTAC Filter Regulator PT1 Low Pressure 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 GFR600C25MLJF2K is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration carries a PT1 (1 inch) PT-thread port, a manual drain bowl in aluminium alloy, a 40 um standard filter element, the low-pressure regulator type, an embedded square gauge with psi scale, and a fitted reverse/check valve. No mounting bracket is included (code J). Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 inch to 1 inch, a choice of manual, automatic or differential-pressure drains, a 40 um standard or 5 um (code W) filter element, square or round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm flow and datasheet figures 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.

On a packaging machine's carton-forming section, this unit filters water and debris out of the shop air and holds a steady low-pressure set point for the fold and clamp cylinders, with the manual drain bled at shift start.
Feeding positioners and pneumatic actuated valves on a water-treatment skid, the 40 um element protects the pilot circuit from particulate while the low-pressure regulator type holds the gentle set point the actuator needs.
On a bottling conveyor, the stopper and pusher cylinders run on air from this unit: the aluminium bowl with manual drain sheds condensed water, the check valve holds the downstream circuit if supply dips, and the psi gauge gives operators a direct reading.
Start with the size and port: the 600 size with its PT1 (1 inch) port is the largest step in the GFR range, so match it against the air demand of your circuit. Because flow is published as curves and not as a single rated number, ask us to confirm sizing against your application before ordering. This unit is the low-pressure regulator type; its exact adjustment range is not published in our data, so confirm the set point you need with us. The manual drain (code M) suits installations where an operator can bleed the bowl on a routine; choose automatic or differential-pressure drain codes if the bowl must clear itself. Filter grade is the 40 um standard; order the W code for the 5 um element if downstream equipment needs finer filtration. The fitted square gauge reads in psi; MPa and bar scales and an external round gauge are options. Thread is PT as standard, with G and NPT available to order, and brackets can be added if this no-bracket (J) configuration needs panel fixing.
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 quote a rated flow number for this unit. Tell us your application and required flow, and we will confirm the sizing from the datasheet curves on request before you order.
The M code in GFR600C25MLJF2K specifies a manual drain: an operator opens the bowl drain to expel collected water and dirt. If the installation is unattended, the same size 600 filter regulator can be ordered with an automatic drain (code A) or the default differential-pressure drain instead.
