The AirTAC GFR600C25LF3T 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 GFR600C25LF3T is a size 600 filter regulator: one body that removes water and particulate from compressed air and holds downstream pressure at a set point. This configuration has a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain, and a low-pressure regulator fitted with an embedded square gauge scaled in bar. The metal bowl on this size is aluminium alloy, a mounting bracket is included, maximum 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 from the GFR series, which spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in and PT, G or NPT threads. Drain type, filter grade, gauge scale and reverse-valve options let you match the unit to your line. We confirm flow and other datasheet figures on request, since AirTAC publishes flow as curves rather than a single rated number.

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, low-pressure regulated air to spray guns in a finishing booth, where the 40 um element keeps water and debris out of the gun and the low-pressure regulator holds a gentle set point.
Supplying treated air to low-pressure clamping circuits on woodworking presses and fixtures, where the combined filter and regulator in one body saves panel space at the 1 in port size.
Providing filtered, gently regulated air for low-pressure blow-off and air-assist nozzles along a packaging conveyor, with the differential-pressure drain ejecting collected water as the line runs.
Size 600 with a 1 in NPT port is the largest step in the GFR range; step up or down by port size against the flow your line needs, and ask us to check the flow curve before ordering. The regulator on this unit is the low-pressure type, intended where set points sit below the standard range - its exact adjustment range is not published, so confirm your target set point with us. Filtration is the 40 um standard element (5 um available as code W), the drain is differential-pressure, and the gauge is the embedded square type scaled in bar; an external round gauge and MPa or psi scales are order options. Thread is NPT here, with PT as the standard and G also available, and the 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Send us your line pressure, set point and expected air demand, and we will confirm sizing against the datasheet curve before you order.
The L code marks the low-pressure regulator variant, intended for set points below the standard range. Its exact adjustment range is not published in the catalogue, so tell us your target set point and we will verify it from the datasheet before ordering.
