The AirTAC GFR60020MJF3WTK 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 AirTAC GFR60020MJF3WTK is a size-600 filter regulator: it removes water and particulate from compressed air and holds downstream pressure steady in a single body. This configuration is fitted with a 5 um filter element (code W, finer than the 40 um standard), a manual drain for the aluminium alloy bowl, an embedded square gauge scaled in bar, and a reverse/check valve (code K) that holds downstream pressure if the upstream supply drops. The port is 3/4 in with NPT thread, and the unit carries no mounting bracket. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing). With manual drainage, the regulator adjustment range is 0.05-0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT, G or NPT thread, differential-pressure, automatic or manual drainage, 40 um or 5 um filtration, gauge scale options, and an optional reverse/check valve. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm the datasheet and sizing 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. 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.

| 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. |

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.

Installed at the drop from a 3/4 in compressed-air main to a production cell, cleaning water and particles from the supply and holding a steady regulated pressure to the machines on that line.
Feeding filtered, regulated air to pneumatic conveyor drives, gate cylinders and hold-down clamps, with the check valve holding the set pressure if the main supply dips.
Supplying the finer 5 um air quality that spray guns and finishing stations need, with the bar-scaled gauge letting operators verify and adjust the regulator setting at the point of use.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when the line's required flow is high and step down to 200/300/400 if the demand is lighter - flow is published as curves, not a single rating, so let us confirm the match before you order. This unit already carries the finer 5 um element (the standard element is 40 um), manual drainage (the differential-pressure and automatic drain options are available elsewhere in the family), a square gauge scaled in bar (MPa and psi scales exist), and a reverse/check valve. Thread is NPT here; PT is the standard option and G is also available to order. A mounting bracket is omitted on this code but can be specified on other variants.
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 the GFR series as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure, set pressure and air demand and we will confirm the flow and sizing from the datasheet on request before you order.
The M in the code specifies manual drainage of the aluminium alloy bowl, so an operator drains it rather than relying on the differential-pressure or automatic drain options available on other GFR variants. The W specifies the 5 um filter element instead of the 40 um standard, for finer particle removal. The K adds a reverse/check valve, and the square gauge on this unit is scaled in bar.
