The AirTAC GFR600C25LJNT 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 GFR600C25LJNT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration has a 1 in NPT port, the standard 40 um filter element, a differential-pressure drain in the metal bowl (aluminium alloy at size 600), and the low-pressure regulator type. No gauge is fitted and no mounting bracket is supplied, so plan your panel or wall fixing accordingly.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drain, a 5 um element option, and PT, G or NPT threads. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing). Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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.

Installed at the 1 in take-off from a plant air main, it filters water and particulate out of the supply and holds a steady low-pressure setting to the packaging hall's distribution legs.
Feeding a bottling or food line's conveyor blow-off and clamp circuit, it cleans the air reaching the nozzles and keeps the regulated pressure stable as stations cycle.
On lines where web tension rollers and guide cylinders run at reduced pressures, the low-pressure regulator type lets the circuit be set below standard regulator ranges while the 40 um element protects the actuators.
Start with the port and size: this unit steps up to 1 in NPT on the size 600 body, the largest in the GFR range, so match it against the air demand of the circuit it feeds. Choose the drain type for the installation: this unit's differential-pressure drain bleeds automatically as flow passes through, while automatic and manual drains are available in the family. The 40 um element is the standard grade; a 5 um element (code W) is offered where finer filtration is needed. Thread is NPT here, with PT and G available as order options, and brackets can be added on request.
Because this is the low-pressure regulator type, confirm the set-point range you need before ordering - we will check it against the datasheet. Flow for the GFR600 is published as curves, not a single rated figure, so send us your application details and we will confirm sizing before you commit.
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 flow for the GFR600 as performance curves rather than a single rated figure, so we do not quote a number. Tell us your inlet pressure and the air demand of your circuit and we will confirm the sizing from the datasheet on request.
The differential-pressure drain bleeds collected condensate automatically as air flows through the bowl, with no operator action needed. The code on this model specifies no gauge and no mounting bracket, so order a gauge and bracket separately if your panel needs them - both are available in the GFR family.
