The AirTAC GFR60025MLJNWTK 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 GFR60025MLJNWTK is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is the size 600 unit with a 1 in NPT port, a 5 um filter element (code W), a manual drain, the low-pressure regulator type, and a reverse/check valve fitted. Its bowl is aluminium alloy, as is standard for the 600 size. No gauge is fitted and no mounting bracket is included.
It is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT to order, a choice of 40 um standard or 5 um filtration, differential-pressure, automatic or manual drains, gauge options and bracket options. Max inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rated figure; ask us to confirm sizing and datasheet figures for your application.

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. |
| 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.

Feeding clean, regulated air to pneumatic tools and actuators at end-of-line drops, where the manual drain is bled during scheduled shift checks and the 5 um element protects downstream equipment.
Supplying filtered, regulated air to conveyor stopper and pusher cylinders on a packaging line, with the reverse/check valve holding downstream pressure if upstream supply dips.
Providing conditioned air to pneumatic positioners and control valves on a process skid, where the low-pressure regulator type and 5 um filtration suit sensitive instrument-air take-offs.
Step up to the size 600 / 1 in port when your line's air demand sits at the top of the G-series range, and confirm that step against the published flow curves before ordering. This unit pairs a 5 um element with a manual drain - choose manual where an operator can routinely bleed the bowl, or ask about automatic and differential-pressure drain versions. It is the low-pressure regulator type; its exact adjustment range is not published, so confirm the range against your setpoint with us. No gauge is fitted, but gauge and scale options exist if you want a visual setpoint reference. The thread here is NPT; PT is standard and G is orderable. No bracket is included, though brackets are optional.
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 figure, so we do not quote a number. Send us your application's air demand and we will confirm the sizing against the datasheet curves on request before you order.
Code M in the model means the bowl is drained by an operator opening the drain, which suits installations covered by routine maintenance rounds. If manual bleeding is impractical, the same size is available with an automatic or differential-pressure drain - ask us for those variants.
