The AirTAC GFR600C25LF3WT AirTAC Filter Regulator 1 in NPT 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 GFR600C25LF3WT is an AirTAC GFR-series filter regulator: a single body that removes water and particulate from compressed air and then regulates downstream pressure. This size 600 unit is configured with a 1 in NPT port, a 5 um filter element (the finer of the two published grades), a differential-pressure drain, a low-pressure regulator and an embedded square gauge scaled in bar. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and can be ordered with 40 um or 5 um filtration, differential-pressure, automatic or manual draining, standard or low-pressure regulation, square or external round gauges in MPa, psi or bar scales, and PT, G or NPT threads. The size 600 bowl is aluminium alloy. Flow is published as curves rather than a single rating, 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.

Mounted at the drop of a stamping or pneumatic press line, it filters plant air to 5 um and holds a steady low-pressure supply to the press cylinders, with the bar gauge giving operators a local set-point readout.
Feeding the air cylinders on a carton-forming or case-packing conveyor, the unit strips water and fine particles before regulation so grippers and pushers cycle on clean, stable low-pressure air.
Installed ahead of the workholding clamps on a CNC machining cell, it conditions shop air to 5 um and regulates it to the low pressure the clamping circuit needs, with the square gauge confirming the setting.
Match the size and port to the air demand of the circuit: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range (sizes 200, 300, 400, 600; ports 1/8 to 1 in). This configuration carries the 5 um element instead of the 40 um standard - choose 5 um where downstream valves, cylinders or instruments need finer air - and drains condensate by differential pressure, with automatic or manual drain available as order options. The regulator is the low-pressure type; its exact adjustment range is not published in the catalogue, so confirm your set point with us before ordering. The embedded square gauge is scaled in bar, with MPa and psi scales and an external round gauge as options. Thread here is NPT, with PT (the standard) and G available to order, and a mounting bracket is included.
Flow for the GFR series is published as curves, not a single rated figure, so no flow number is quoted here. Send us your application details and we will confirm sizing and the full 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 GFR flow as curves rather than a single rated figure, so we do not quote a number here. Ask us for the datasheet and we will confirm the flow curve for this size 600, 1 in NPT unit against your application before you order.
The L in the code marks the low-pressure regulator variant, intended where the set point sits below the standard type's range. The catalogue does not publish its exact adjustment range, so tell us your required pressure and we will verify it from the datasheet. Everything else - 5 um filtration, differential-pressure drain, square bar gauge, 1 in NPT port - is as decoded.
