The AirTAC GFR60020ALJNWT AirTAC Filter Regulator NPT3/4, 5 um 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 automatic 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 GFR60020ALJNWT is a filter regulator: water and particulate removal plus downstream pressure regulation in a single body. This size 600 unit is built around a 3/4 in NPT port and carries a 5 um filter element (code W) for finer air cleanliness than the standard 40 um grade. The automatic drain bleeds collected condensate from the bowl without operator attention, and the bowl on this 600 size is aluminium alloy. The regulator is the low-pressure type, and this configuration is supplied without a gauge and without a mounting bracket.
This is a genuine AirTAC part from the GFR filter-regulator family, which spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge options and PT, G or NPT threads. Flow for this series is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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. |
| (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 a packaging line's distribution header, the 3/4 in NPT port and 600 frame handle the branch supply while the 5 um element and automatic drain keep water and fine debris out of downstream valves on a line that runs without an operator at the drop.
On a CNC fixture or pneumatic press station, the GFR filters the shop air to 5 um and holds a steady regulated supply to clamp cylinders, with the low-pressure regulator type suited to circuits that work below standard line pressure.
At the head of a conveyor sorting line, the unit conditions the branch feeding diverters, stoppers and gate cylinders, the aluminium alloy bowl with automatic drain handling condensate at a busy node nobody opens on a schedule.
Choose GFR size and port against the air consumption of the machine it feeds: this unit steps up to 3/4 in NPT on the 600 frame, the largest in the range. Drain type is a real decision: automatic drain (fitted here) suits unattended or hard-to-reach installations, while manual and differential-pressure drains are available in the family. The 5 um element (code W) is the finer of the two published grades; the standard grade is 40 um. Gauge (square embedded or external round, with MPa, psi or bar scale), bracket, and PT or G thread are orderable options; this code omits the gauge and bracket and specifies NPT. Flow for this series is published as curves, not a single rating, 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. 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 application and we will confirm the flow and sizing figures from the datasheet on request before you order.
The N in the code GFR60020ALJNWT means no gauge is fitted. GFR units can be ordered with an embedded square gauge or an external round gauge, with MPa, psi or bar scale, so if you want a local pressure reading, ask us to quote the gauge-equipped variant of the same size.
