The AirTAC GFR600C25MLC1WT 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 GFR600C25MLC1WT is a filter regulator: water-and-particulate filtration and pressure regulation combined in one body, with a drain bowl but no lubricator. This size 600 unit is built for a 1 in NPT line and carries the 5 um filter element (code W), a manual drain on the aluminium alloy bowl, the low-pressure regulator type, and an external round gauge reading in MPa. A mounting bracket is included and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
It is a genuine AirTAC part. The GFR series spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and can be ordered with a 40 um standard or 5 um element, differential-pressure, automatic or manual draining, embedded square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the datasheet figures for your line 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.

Filtering and regulating the 1 in branch that feeds capper and palletizer cylinders on a beverage bottling line, with the 5 um element protecting downstream solenoid valves.
A filtered, regulated drop ahead of clamps and tool-change actuators on a CNC machining cell, with the round MPa gauge giving the setter a direct line-pressure readout.
Supplying regulated air to quarter-turn valve actuators on a water-treatment filter bed, where the low-pressure regulator type and manual drain suit a supervised plant room.
Size 600 with a 1 in port sits at the top of the GFR range; step down through 200/300/400 (1/8 to 3/4 in) if your demand is smaller - the published flow curves, not a single rating, decide the right step, so send us your air demand and we will confirm sizing. This unit pairs the 5 um element with a manual drain: choose automatic draining where the bowl is hard to reach, or the differential-pressure default where a drop in inlet pressure can signal bowl loading. The low-pressure regulator type suits lower set-pressure circuits; its exact adjustment range is not published in our data, so confirm your set point with us. Gauges can be the embedded square type or an external round gauge in MPa, psi or bar scales; thread is NPT here, with PT as the standard and G also orderable; a bracket is included (code J deletes it).
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 and air demand and we will confirm the datasheet curve for this exact model before you order.
This GFR600 carries the L designation, meaning the regulator is the low-pressure variant for lower set-pressure circuits. The exact adjustment range for this variant is not published in our data, so tell us the set point you need and we will check it against the datasheet. The unit otherwise keeps the 5 um element, manual drain and round MPa gauge decoded from its code.
