The AirTAC GFR60020MJF3WT AirTAC Filter Regulator NPT3/4 5um 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 GFR60020MJF3WT is an AirTAC GFR600 filter regulator: one body that removes water and particulate from compressed air and sets downstream pressure. This configuration is the largest size in the family, with 3/4 inch NPT ports, a fine 5 um filter element (the W grade, versus the standard 40 um), a manual drain on the bowl, and an embedded square pressure gauge reading in bar. The bowl on this 600 size is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), the standard regulator covers 0.05-0.9 MPa (7-130 psi), and the operating temperature range is -5 to 70 C (non-freezing). No mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, gauge scale options, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing figures 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 0.05 - 0.9 MPa (7 - 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.
| 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)). |
| (blank) | Standard 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. |
| 3 | Gauge scale: bar. 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 filtered, pressure-set air to a workshop pneumatic press or clamping fixture, with the 5 um element protecting cylinders and valves from particulate carryover.
Conditioning the 3/4 inch air main serving a packaging or case-erecting line, where the regulator holds a stable setpoint for diverters and seal cylinders.
A filtered and regulated drop point on a factory compressed-air ring main, with the manual drain emptied during scheduled rounds and the bar gauge read at a glance.
Size and port are the first decision: the 600 step with 3/4 inch NPT ports suits lines with substantial air demand, while 200/300/400 cover smaller flows - match the port step to your required flow rather than to pipe size alone. Drain type is a real choice here: manual drain (this unit) needs an operator to open the bowl drain periodically; automatic or differential-pressure drain suits unattended installations. The 5 um element (code W) is the finer option for sensitive downstream equipment; 40 um is the standard grade. The embedded square gauge reads bar; MPa and psi scales and an external round gauge are alternatives. PT is the standard thread, with G and NPT as order options, and brackets are optional (not fitted on this code).
Because AirTAC publishes flow as curves rather than a single rated number, 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.
The M code in GFR60020MJF3WT specifies a manual drain: condensate is released by opening the bowl drain during maintenance rounds. Automatic and differential-pressure drain versions are available in the same series for installations that cannot rely on regular operator attention.
