The AirTAC GFR60020MLJNTK 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 GFR60020MLJNTK is a filter regulator: one body removes water and particulate from compressed air and regulates the downstream pressure. This size 600 unit has a 3/4 in NPT port, a manual drain, a 40 um filter element and an aluminium alloy bowl. The L code marks the low-pressure regulator type, and a reverse/check valve is fitted. No gauge is supplied with this configuration and no mounting bracket is included.
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in and PT, G or NPT thread options. Drain type, filter grade (40 um standard, 5 um optional), gauge and bracket choices let you match the unit to the line. Flow and other datasheet figures are published as curves rather than a single rating, so we confirm them 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. |
| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 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. |
| K | Reverse-flow (reflux) valve fitted. |
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 feeding low-pressure actuators on a packaging line: the 40 um element strips water and debris before the control valves, and the manual drain is emptied during planned changeovers.
A filtered, regulated supply for gate and diverter cylinders on a conveyor system, with the low-pressure regulator type for circuits that run below standard regulated pressure and a reverse/check valve fitted in this configuration.
Setting a reduced supply pressure for a clamping or holding fixture that calls for lower-than-standard regulated pressure, with the manual drain checked at the start of each shift.
Size the unit against the air demand of your circuit: size 600 is the largest step in the GFR range and carries a 3/4 in NPT port here (PT is the standard thread; G and NPT are order options). Choose the drain to suit the installation: manual drain, as on this code, suits points where an operator drains on a schedule, while automatic and differential-pressure drains suit unattended positions. Filtration is 40 um standard; specify W for a 5 um element where finer protection is needed. Gauge and bracket options vary by code. Flow for this series is published as curves, not a single rated figure, so ask us to confirm sizing against your application before ordering.
Quick checklist
The aluminium-alloy bowl on the GFR600 suits harsher environments than a PC bowl. The reflux valve permits reverse flow through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves rather than a single rated figure, so we do not quote a number. Send us your air demand and operating pressure and we will confirm the sizing from the datasheet on request.
L marks the low-pressure regulator type; the exact regulation range for this type is not published in our data, so we confirm it on request. The N code means no gauge is fitted with this unit. Gauge options, including an embedded square gauge and an optional external round gauge, are available in the GFR family if you need a pressure indication.
