The AirTAC GFR600C20MLJNTK AirTAC Filter Regulator NPT3/4 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 AirTAC GFR600C20MLJNTK is a filter regulator: water and particulate removal plus pressure regulation in a single body. This 600-size unit is ported 3/4 in NPT and carries the standard 40 um filter element with a manual drain bowl in aluminium alloy. The regulator is the low-pressure type, suited to circuits that hold a lower set pressure than a standard unit is intended for; the exact adjustment range for the low-pressure type is not published, so confirm it with us for your set point. No gauge is fitted with this code, and a reverse/check valve is included. 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 from the GFR600 series, the largest of the four GFR sizes (200/300/400/600). Across the series you can order automatic or differential-pressure drains instead of manual, a 5 um element (code W), a built-in square gauge or an external round gauge in MPa, psi or bar scales, G or PT threads, and a mounting bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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.

Feeding filtered, regulated air to the cylinder bank of a carton-forming and palletizing cell, where the 3/4 in line size serves a whole machine drop and the low-pressure regulator holds a modest set point for the actuators.
Supplying the hold-down and pusher cylinders on a bottling hall conveyor run, with the 40 um element keeping scale and pipe debris out of the valves and the manual drain bled at shift start.
Regulating supply to air-to-open process valves on a water treatment skid that operates at low set pressures, with the reverse/check valve holding the circuit if upstream air is interrupted.
Start with the port step: this unit is 3/4 in NPT on the 600 frame, the largest GFR size, chosen when line size and air demand point to the top of the range. Match the drain to the site: manual drain (this code) needs an operator to bleed the bowl, while automatic or differential-pressure drains suit unattended installations. The standard element is 40 um; order the W variant for 5 um if downstream equipment needs finer filtration. Gauges are optional - a built-in square gauge or an external round gauge in MPa, psi or bar scales - and this code ships without one. Threads come as PT (standard), G (BSPP) or NPT; brackets are optional and not included here.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated number, so send us your flow and pressure requirements and we will confirm the selection against the datasheet before you order. The same applies to the adjustment range of the low-pressure regulator type fitted to this code.
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 series as curves rather than a single rated figure, so there is no one l/min or SCFM number we can quote. Send us your required flow and working pressure and we will confirm the sizing and the full datasheet for this exact model on request.
The M in the code specifies a manual drain: condensate collects in the aluminium alloy bowl and an operator opens the drain to bleed it off. It suits attended installations on a regular maintenance round. For unattended or hard-to-reach positions, order the same 600-size unit with an automatic (code A) or differential-pressure (blank) drain instead.
