The AirTAC GFR60025MLJF3WT AirTAC Filter Regulator 1 in NPT 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 PT1" 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 GFR60025MLJF3WT is a filter regulator: water and particulate removal plus downstream pressure regulation in a single 600-size body. This configuration carries a 1 in NPT port, a 5 um filter element (the finer W grade), a manual drain on the bowl, and the low-pressure regulator type. The 600-size bowl is aluminium alloy, and the unit comes with the embedded square gauge scaled in bar; no mounting bracket is fitted and no reverse/check valve is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600, with port options, drain types (differential-pressure, automatic or manual), 40 um or 5 um elements, gauge scales in MPa, psi or bar, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet 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. 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. |
|---|---|
| 25 | Port size PT1". 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. |
| (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.

Filtering and regulating the 1 in supply line that feeds a bottling hall's pneumatic distribution header, with the 5 um element protecting downstream valves and cylinders from water and fine dirt.
Conditioning the compressed air that drives conveyor stopper and lift actuators on an automotive assembly line, holding a steady regulated pressure so indexing stays repeatable through the shift.
Supplying filtered, regulated air to large pneumatically actuated butterfly and knife-gate valves at a water treatment works, with the manual drain emptied during scheduled maintenance rounds.
Start with the port step: this unit is 600 size with a 1 in NPT port, the largest step in the GFR range, so match it to the main-line air demand of the machine or header it feeds. The 5 um element suits points of use that need finer particulate control than the 40 um standard; the manual drain means an operator drains the bowl on a routine, so choose automatic or differential-pressure drain if nobody is on site to do it. Gauge scale here is bar; MPa and psi scales are alternatives, and an external round gauge is optional. Thread is NPT on this code; PT is the catalogue standard and G is also orderable. A bracket can be added on codes that carry it.
Because flow is published as curves and not a single rated figure, send us your air demand and we will confirm the sizing against the datasheet before you order.
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 number, so we do not quote one. Send us your line pressure and air demand and we will confirm the flow figures from the datasheet for this exact 1 in NPT, 5 um configuration on request.
The M in the code sets a manual drain: an operator opens the bowl drain to expel collected water. It is the right choice where the unit is inspected routinely. If the installation is unattended, order a code with automatic or differential-pressure drain instead; the regulation range also differs by drain type, and we can confirm the low-pressure range from the datasheet on request.
