The AirTAC GFR600C25MLJNTK 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 GFR600C25MLJNTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This size-600 unit carries a 1 in NPT port, a manual drain on the aluminium alloy bowl, and the standard 40 um filter element. It is the low-pressure regulator type, is supplied without a gauge and without a mounting bracket, and includes a reverse (check) valve. 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 port sizes from 1/8 to 1 inch, and options for automatic or differential-pressure drains, a 5 um element (code W), gauges, brackets and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures for your application 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 air that feeds the clamp cylinders on a machining cell, so wet, dirty shop air is cleaned before it reaches the fixtures and clamp pressure is held at the setpoint the fixture was designed around.
A low-pressure regulator type like this suits branch lines on a plant floor where spray nozzles, air tables or sensitive actuators need a lower setting than the main header delivers, with the 40 um element keeping the downstream devices clean.
Supplying filtered, regulated air to the gate and divert cylinders on a packaging conveyor, with the fitted reverse (check) valve helping guard the unit against backflow from the downstream side of the line.
Within the GFR range the real choices are: size and port (200/300/400/600, 1/8 to 1 inch) stepped against the flow your circuit needs; drain type (manual, as here, or automatic or differential-pressure); filter element 40 um standard or 5 um with code W; regulator type standard or low-pressure; gauge fitted or omitted, with square or round dials and MPa, psi or bar scales; thread PT (the standard), G or NPT; and bracket or no bracket. This configuration is size 600, 1 in NPT, manual drain, 40 um element, low-pressure type, no gauge, check valve fitted, no bracket. Because AirTAC publishes flow as curves rather than a single rated figure, send us your application details 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, not as a single rated figure, so we do not quote a number here. Send us your application details - line pressure, downstream demand and the pressure drop you can accept - and we will confirm the sizing against the datasheet on request.
The N in this configuration means no gauge is supplied. Across the GFR series you can order a variant with an embedded square gauge or an external round gauge, with MPa, psi or bar scales. Tell us which scale and dial style you want and we will identify the matching code.
