The AirTAC GFR600C25MLJF2GK AirTAC Filter Regulator G1 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 GFR600C25MLJF2GK is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in a single body, with no lubricator. This size 600 unit is built with a G1 (1 inch) G-thread port, a manual drain, the standard 40 um filter element and the low-pressure regulator type. It comes with the embedded square gauge fitted (psi scale) and a reverse/check valve, and has no mounting bracket. Because this is size 600, the bowl is aluminium alloy rather than polycarbonate.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, and options that include G or NPT thread, automatic, manual or differential-pressure drain, a 5 um element (code W), gauge scale in MPa, psi or bar, and bracket choice. Max working (inlet) pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. 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.

Supplies filtered, regulated air to the hold-down clamps and pneumatic vices on a woodworking CNC router, using the low-pressure regulator type where the clamping circuit calls for it.
Feeds clean, regulated air to the cylinder and actuator bank on a bottling or canning line, with the manual-drain aluminium bowl suited to a supervised plant room where an operator checks condensate.
Placed ahead of the air knives on a conveyor drying station, it removes water and particles from the supply and holds the knife pressure steady across the shift.
Size and port are the first choice: sizes 200 to 600 step the port up from 1/8 to 1 inch along with air-handling capacity, so pick the size that matches the demand of the machine downstream. This unit is already fixed at size 600 with a G1 (1 inch) port. Drain type is a real decision: the manual drain on this model needs an operator to open the bowl drain, while automatic and differential-pressure drains discharge condensate without attention. Filter grade is 40 um standard or 5 um with code W for finer protection. Gauge scale can be MPa, psi or bar, thread can be PT (standard), G or NPT to order, and the bracket can be included or omitted (J = no bracket). Flow is published as curves, not a single rated figure, so send us your application details and we will confirm sizing against the datasheet before you order.
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. Send us your application details and we will confirm the flow and the full datasheet for the GFR600C25MLJF2GK on request before you order.
This model uses a manual drain: an operator opens the bowl drain to discharge collected condensate, which suits a supervised plant room. Automatic and differential-pressure drain versions are available in the same GFR family if you prefer unattended drainage.
