The AirTAC GFR600C25MLF3TK AirTAC Filter Regulator NPT1 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 GFR600C25MLF3TK is a size 600 filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This configuration is built for a 1 inch NPT port, uses the standard 40 um filter element, and has a manual drain bowl in aluminium alloy, the material used for the 600 size. The regulator is the low-pressure type, an embedded square gauge with a bar scale is fitted, and a reverse/check valve is included. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C, non-freezing. A mounting bracket is included.
This is a genuine AirTAC part from the GFR filter-regulator line, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, standard or low-pressure regulation, gauge scales in MPa, psi or bar, and an optional reverse/check valve. Flow is published as curves rather than a single rating, so ask us to confirm flow and any other datasheet figure for your application before ordering.

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.

Point-of-use air preparation for the pneumatic cylinders and grippers on a bottling or filling line, where the 1 inch NPT connection feeds a main header and the low-pressure regulator sets a gentle working pressure for delicate handling of containers.
Feeding the air cylinders that divert, stop and align product on conveyor systems, with the 40 um element keeping pipe scale and condensed water out of directional valves and the manual drain cleared during scheduled line checks.
Supplying filtered, regulated air to quarter-turn actuators on process valves in a plant skid, where the reverse/check valve holds the set circuit against backflow and the bar-scale gauge gives operators a local pressure readout.
Start with the port step: this unit is the size 600 body on a 1 inch NPT connection, the largest in the GFR range, so match it to lines plumbed at 1 inch and to the flow your circuit needs. Because flow is published as curves and not a single rated figure, send us your application details and we will confirm sizing against the datasheet before you order. On this model the drain is manual, which suits installations where an operator can bleed the bowl on a routine; if the unit will sit unattended, ask about the automatic-drain version instead. The filter element here is the standard 40 um grade; if downstream equipment needs finer filtration, the W option gives a 5 um element. The fitted square gauge reads in bar; MPa and psi scales are available, and an external round gauge is an option. This is the low-pressure regulator type, so confirm the adjustment range suits your circuit when you enquire. Thread is NPT here, with PT (the standard) and G as order options, and a mounting 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 this series as curves rather than a single rated figure, so we do not quote one number. Tell us your line pressure and the air demand of your equipment and we will confirm the flow from the datasheet for this exact 1 inch NPT, size 600 configuration before you order.
The M in the code specifies a manual drain: the bowl is emptied by hand, which suits attended installations on a maintenance routine. If the unit will run unattended, the same size 600 filter regulator can be ordered with an automatic drain (code A) or the differential-pressure drain that is the series default - just ask and we will decode the right variant with you.
