The AirTAC GFR600C20MLJF1TK 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 AirTAC GFR600C20MLJF1TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This 600-size unit is fitted with a 3/4 in NPT port, a 40 um standard filter element and a manual drain, so condensate is released by operator action rather than automatically. It is the low-pressure type, carries an embedded square gauge scaled in MPa, and includes a reverse (check) valve. The metal bowl at size 600 is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with a choice of port sizes, G/NPT thread options, drain types, 5 um (W) or 40 um filtration, gauge scale and bracket options. Max 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 flow and datasheet 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.

Installed at a 3/4 in air drop on a factory ring main, it filters line scale and condensate from the compressed air and holds a steady regulated supply to the machines served by that drop, with the MPa gauge giving a local pressure readout.
Placed ahead of the pneumatic clamps and tool-change cylinders on a CNC machining centre, it removes water and particulate that would score seals and seats, and regulates the clamp pressure from the embedded square gauge.
Mounted on the air supply to sorting and diverting cylinders on a packaging conveyor line, it conditions the air and keeps actuator pressure stable shift after shift, with the manual drain cleared during scheduled line stops.
Choose the GFR600 size step and its 3/4 in NPT port against the pipe bore and the flow your line needs - larger sizes carry larger ports and more flow, but the catalogue publishes flow as curves, not a single rating, so ask us to confirm sizing against your application before ordering. This unit is the low-pressure type; its exact adjustment range is not published in the catalogue, so confirm the set pressure with us if your circuit runs below standard ranges. Drain is manual (code M): condensate must be drained by hand, so pick automatic or differential-pressure drain codes instead if the installation is unattended. Filtration is the 40 um standard grade; specify the W code for the 5 um option where downstream equipment needs finer air. The embedded square gauge is scaled in MPa; psi or bar scales and an external round gauge are order options. Thread here is NPT; PT is the standard catalogue thread and G (BSPP) is also available to order. A mounting bracket is not included with this code (J), and a reverse/check valve is fitted (K).
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 we do not quote a rated flow number. Tell us your line pressure and the flow your equipment needs and we will confirm the sizing against the datasheet curves on request before you order.
The M code means condensate collected in the aluminium alloy bowl is released by manual operation rather than automatically, so the drain should be operated during routine checks or scheduled stops; automatic (A) and differential-pressure (blank) drain versions are available for unattended installations. This unit is the low-pressure type, and its exact regulation range is not published in the catalogue, so confirm the set pressure you need with us on request.
