The AirTAC GFR60020MLJF1T 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 PT3/4" ports, a manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60020MLJF1T is a size-600 filter regulator: water and particulate removal plus pressure regulation combined in one body. This configuration is built around a 3/4 in NPT port, a 40 um filter element, a manual drain on the bowl, and a low-pressure regulator type with an embedded square gauge scaled in MPa. The aluminium alloy bowl suits the large 600-size body, and the unit is ordered without a mounting bracket.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in to 1 in. Across the range you can choose manual, automatic or differential-pressure drains, a 5 um element (code W), gauge scales in MPa, psi or bar, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, so ask us and we will confirm the 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 130 psi)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | Filtering grade 40 µm. Only 40 µm (blank) and 5 µm (W) exist. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| (blank) | No reverse-flow valve (the default). |
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 low-pressure pneumatic actuators on a metal stamping line from a 3/4 in main drop, with water and scale knocked out of the compressed air before it reaches the valves.
Supplying filtered, regulated air to conveyor-mounted clamp and pusher cylinders on a packaging line, where the manual drain suits a shift-based maintenance routine.
Conditioning shop air for a laboratory or pilot-plant pneumatic test bench that runs at reduced setpoints, where the low-pressure regulator type and MPa gauge keep the supply readable and controlled.
Start with the port step: this unit is the 600 size with a 3/4 in NPT thread, the largest in the GFR range - step down to 300 or 400 if your line runs smaller ports, but match the size to the flow your circuit actually needs. Next, pick the drain: this version is manual (code M), so an operator drains the bowl; choose automatic or differential-pressure if the installation is unattended. The 40 um element is the standard grade; specify W for the 5 um option where downstream equipment demands finer filtration. The embedded square gauge here reads in MPa; psi and bar scales are available, and an external round gauge is an option. Threads are ordered as PT (standard), G or NPT, and brackets are optional - this unit is supplied without one. Because flow is published as curves rather than a single rating, 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. Tell us your line pressure, setpoint and downstream consumption, and we will confirm the flow data from the datasheet for this 3/4 in size on request.
The M in the code means the bowl is drained by hand rather than automatically. A manual drain suits installations that are checked regularly as part of a maintenance round. If the unit will sit unattended, ask about the automatic or differential-pressure drain versions of the same GFR600 configuration.
