The AirTAC GFR60020MLJNWTK AirTAC Filter Regulator NPT3/4 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60020MLJNWTK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built for 3/4 in NPT ports, carries a 5 um filter element (the fine grade, code W), drains collected condensate by hand via the manual drain, and is the low-pressure regulator type. No gauge is fitted (code N) and no mounting bracket is included (code J), while a reverse/check valve is fitted (code K) to hold downstream pressure when the supply is removed. The size 600 bowl is aluminium alloy. 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 from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in up to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um standard or 5 um fine filtration, gauge options and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures for your application before ordering.

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. |
| W | Filtering grade 5 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.

Feeds filtered, regulated air to a clamping or forming press that runs at reduced supply pressure, with the 5 um element protecting valve spools and cylinders from water and grit.
Sits at the drop point of a packaging line's 3/4 in air main, conditioning air for conveyor diverters and bagger cylinders while the manual drain lets maintenance bleed the bowl on schedule.
Installed in a control panel upstream of directional valves and air logic on custom machinery, where the reverse/check valve holds the circuit's set pressure during supply loss.
Step up or down the size ladder (200 / 300 / 400 / 600) to match the port and flow path your line needs; size 600 with 3/4 in ports suits higher-flow branches. Choose the drain to match attendance: manual (as here) where an operator can bleed the bowl, automatic for unattended draining, or the differential-pressure default. Pick 5 um filtration (this model) when downstream equipment needs finer air than the 40 um standard element provides. This unit is the low-pressure regulator type; its exact adjustment range is not published in the sheet we work from, so confirm it with us against your set pressure. Gauge is not fitted; gauge and scale options exist elsewhere in the family. Thread here is NPT, with PT standard and G also orderable, and this code omits the mounting bracket.
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 family as curves, not as a single rated number, so we do not quote a figure. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request before you order.
The code decodes it that way: M is the manual drain, so condensate is bled by hand rather than automatically, and N means no gauge is fitted. If your installation runs unattended or needs a visible setpoint, ask us about GFR600 variants with automatic drain and a gauge.
