The AirTAC GFR600C25JNT 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 GFR600C25JNT is an AirTAC GFR-series filter regulator: water and particulate filtration plus pressure regulation combined in one body. This 600-size unit is threaded 1 in NPT and carries the standard 40 um filter element with a differential-pressure drain; the bowl on this size is aluminium alloy. The regulator is the standard type with a setting range of 0.15-0.9 MPa (20-130 psi) against a maximum inlet pressure of 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), and no pressure gauge is fitted on this configuration.
This is a genuine AirTAC part. The GFR family spans 200, 300, 400 and 600 sizes with ports from 1/8 in to 1 in, and options include a 5 um element (code W), automatic or manual drain, a fitted gauge, G (BSPP) or NPT thread in place of the PT standard, and a mounting bracket. Flow for the series 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.

Installed on the 1 in drop from a compressor receiver to a factory distribution header, filtering condensed water and pipe scale while holding a steady regulated pressure to the whole line.
Feeding pneumatic clamps and fixtures on a CNC cell, where the regulator holds a fixed clamping pressure and the 40 um element stops rust and dirt reaching the cylinders.
Supplying air to conveyor stoppers, pushers and sorting cylinders on a packaging line, with the filter-regulator keeping the supply clean and at a stable set pressure.
Choose the size by port and flow: 600 is the largest GFR size, with a 1 in port here, so step down to 300 or 400 if your circuit runs smaller ports. Drain comes as differential-pressure (the default), automatic (A) or manual (M); the 40 um element is standard and 5 um (W) suits finer filtration. A gauge can be added - embedded square or external round, with MPa, psi or bar scales - and thread is PT as standard with G (BSPP) and NPT as order options. Note this configuration has no gauge (N) and no bracket (J). Flow is published as curves, not a single rating, so send us your application 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 flow for the GFR series as curves rather than a single rated figure, so no one number is quoted here. Tell us your line pressure, set pressure and expected air demand and we will confirm the flow from the datasheet for this 1 in NPT unit before you order.
No. The N in the code means no gauge is fitted, and J means no mounting bracket. A gauge can be ordered as an option - an embedded square gauge or an external round gauge with MPa, psi or bar scales - and the bracket is also optional.
