The AirTAC GFR600C25ALJF3WT 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 GFR600C25ALJF3WT is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is rated to 1.0 MPa (145 psi) inlet and operates from -5 to 70 C (non-freezing). It is fitted with a 1 in NPT port, a 5 um filter element (code W, against the 40 um standard), an automatic drain that expels condensate from the aluminium-alloy bowl without manual attention, and the low-pressure regulator type. The embedded square gauge on the bar scale gives a clear readout of the regulated outlet, and the unit is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options for PT, G (BSPP) or NPT threads, manual, automatic or differential-pressure drains, 40 um or 5 um filtration, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rated figure, 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.

Feeding filtered, low-pressure regulated air to clamping and holding cylinders on a stamping or press line, with the 5 um element keeping particulate and water out of the directional valves.
Supplying conditioning air to spinning and weaving machines that run at reduced regulated pressure, with the automatic drain keeping condensate out of the machine between shifts.
Regulating supply air for diverters, pushers and gate actuators on a packaging conveyor, with the bar-scale square gauge giving operators a visible setpoint at the machine.
Step up through the GFR sizes (200/300/400/600) until the port and flow capacity match your line; this unit sits at the top of the range with a 1 in NPT port. Choose the drain to suit maintenance: automatic (fitted here) clears condensate by itself, manual needs operator attention, and differential-pressure drains on rising pressure drop. Choose 40 um for general protection or 5 um (this unit) for finer filtration. Gauge scale can be MPa, psi or bar; thread can be PT (standard), G or NPT; a bracket can be ordered where this no-bracket version is not wanted. Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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. Tell us your line demand and we will confirm the flow curve and correct sizing from the datasheet on request.
The automatic drain (code A) expels collected condensate from the aluminium-alloy bowl on its own, which suits unattended or multi-shift installations. Manual drain needs an operator to open the drain, and differential-pressure drain discharges as the pressure drop across the element rises. All three drain types are orderable within the GFR family.
