The AirTAC GFR600C20MJNT AirTAC Filter Regulator NPT3/4 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 GFR600C20MJNT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and then regulates downstream pressure. This size-600 unit is fitted with a 3/4 in NPT port, a manual drain on the metal bowl, a 40 um standard filter element, and a standard-type regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). No gauge is fitted with this configuration, so add a separate gauge if you need a local pressure readout, and no mounting bracket is included. Maximum working (inlet) pressure is 1.0 MPa (145 psi), and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with a choice of port sizes, PT, G or NPT threads, manual, automatic or differential-pressure drains, a 40 um standard or 5 um (code W) filter element, and gauge options. Because flow for this series is published as curves rather than a single rated figure, we confirm the datasheet and flow figures for your application on request.

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.

Filter and regulate the shop-air feed that powers tool clamps, pallet locators and air blast nozzles on a machining centre, keeping chips and condensate out of the valve stack.
Condition the air feeding cylinder-driven carton sealers, case packers and conveyor diverters, holding a steady regulated pressure so stroke timing stays repeatable through the shift.
Serve as the point-of-use filter regulator on a 3/4 in branch line in a process plant, delivering cleaned, regulated air to pneumatic control panels and air-operated valves.
Start with the port step: this unit is size 600 with a 3/4 in NPT port, the largest step in the GFR range, so match it to your main air supply line and confirm the flow your application needs against the published curves before ordering. The manual drain must be opened by hand to discharge collected condensate, which suits attended installations; choose an automatic or differential-pressure drain code instead for unattended duty. The 40 um element is the standard grade; specify the W code for the 5 um option if downstream equipment needs finer filtration. This configuration ships without a gauge and without a mounting bracket - both are orderable options on other codes. Thread is NPT here; PT is the standard thread and G (BSPP) is also a catalogue option. We confirm sizing against the published flow curves on request 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 GFR600 series as curves rather than a single rated figure, so we do not quote one number. Send us your application details and we will confirm the flow figures from the datasheet on request before you order.
The M in the code GFR600C20MJNT specifies a manual drain: an operator opens it by hand to discharge collected water from the metal bowl. If the unit will run unattended, order the automatic (A) or differential-pressure (blank) drain code instead - both are catalogue options in the same size.
