The AirTAC AirTAC GFR600C25LJF3T 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 GFR600C25LJF3T is an AirTAC GFR-series filter regulator: water-and-particulate filtration and pressure regulation combined in one body. This size-600 unit is built for a 1 in NPT port, carries the standard 40 um filter element, and drains condensate by differential pressure. The regulator is the low-pressure type, and an embedded square gauge scaled in bar is fitted so downstream pressure can be read and set directly. The 600-size bowl is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family is offered in sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, in PT, G (BSPP) or NPT thread, with automatic, manual or differential-pressure drains, a 5 um (W) filter option, gauge and scale choices, and a reverse/check valve option. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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.

Feeding filtered, regulated air to the gripper and capper cylinders on a bottling line, where the low-pressure regulator holds a reduced set point for delicate container handling and the differential-pressure drain keeps condensate out of the valves.
Supplying the stopper and diverting gates along a packaging conveyor, with the 40 um element keeping dust and pipe scale out of the directional valves and the square bar gauge letting line staff check supply pressure at a glance.
Providing clean, regulated pilot air to the positioners of large automated process valves, where the low-pressure type regulator and the 1 in NPT connection suit a dedicated instrument-air branch off the main header.
Choose the size and port against the air demand of the circuit: this unit is size 600 with a 1 in NPT port, the largest step in the range, with smaller sizes stepping down through 3/4 in, 1/2 in and below. Where this unit differs from the standard GFR build is the low-pressure (L) regulator: specify it where the standard adjustment range does not suit the circuit, and confirm the exact adjustment range with us before ordering, as it is not published on the standard sheet. The drain is differential-pressure, which works while the unit is flowing; an automatic (A) or manual (M) drain can be ordered instead if the installation suits it better. The 40 um element is standard; order the W suffix for 5 um. The fitted square gauge reads in bar, and MPa or psi scales, an external round gauge, G or NPT thread and a mounting bracket are all order options. Because flow is published as curves rather than a single rating, send us your flow and pressure requirements 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 GFR600 flow as curves rather than a single rated figure, so there is no one rated-flow number we can honestly quote for the 1 in port. Send us your required flow and working pressure and we will confirm the sizing from the datasheet on request.
This unit drains condensate by differential pressure: the bowl discharges automatically as the pressure difference across the filter builds while air is flowing. If your machine stops and starts often or runs at low flow, an automatic (A) or manual (M) drain can be ordered instead as a catalogue option.
