The AirTAC GFR60025MLF3WTK AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR60025MLF3WTK is a size-600 filter regulator: water and particulate removal plus pressure regulation combined in a single body. This configuration is built around a 1 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type. An embedded square gauge with a bar scale is fitted so the set pressure is visible at the unit, and a reverse (check) valve is included so downstream pressure is held if the upstream supply drops. A mounting bracket is supplied.
This is a genuine AirTAC part from the G-series range, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of differential-pressure, automatic or manual drainage, 40 um or 5 um filtration, and PT, G or NPT threads. Flow figures are published as curves rather than a single rating, so ask us to confirm sizing or any datasheet figure 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. |
|---|---|
| 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. |
| (blank) | Mounting bracket included. |
| (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. |
| 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.

Filtered, regulated supply for the air clamps and grippers that hold trim panels on a body line, with the check valve holding the set pressure if the upstream feed dips.
A single-body filter regulator feeding cylinder and actuator circuits on a palletiser, where the 5 um element protects downstream valves from particulate carryover.
Conditioning and low-pressure regulation on a textile-machine air header, with the bar-scale square gauge letting operators verify the set point at a glance.
Start with the port and size: this unit steps up to the 600 frame with a 1 in NPT connection, the largest in the G-series range, so match it to the pipe diameter and the flow your line needs. Because flow is published as curves rather than one rated number, send us your application details and we will confirm sizing against the datasheet before you order. The 5 um element (code W) suits circuits that need finer filtration than the 40 um standard; the manual drain means an operator opens the bowl drain during checks rather than relying on automatic or differential-pressure action. The fitted square gauge reads in bar; MPa and psi scales are the other catalogue options. Thread is NPT here, with PT (standard) and G available to order, and the bracket is included for panel or wall fixing.
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 G-series as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your line pressure and the flow your application needs and we will confirm the sizing against the datasheet before you order.
The M in the code selects manual drainage: an operator opens the bowl drain during routine checks, instead of the automatic or differential-pressure drain options. The W selects the 5 um element, one grade finer than the 40 um standard, for circuits that need cleaner air. Both are catalogue choices on the GFR600 frame.
