The AirTAC GFR60025MLNTK AirTAC Filter Regulator NPT 1 in is a genuine G-series filter regulator: water separation, 40 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 GFR60025MLNTK is a size 600 filter regulator: one body that removes water and particulate from compressed air and holds the downstream pressure at your set point. This configuration has a 1 in NPT port, a manual drain on the aluminium alloy bowl, a 40 um filter element, and the low-pressure regulator type. A reverse/check valve is fitted, and no gauge is supplied with this code. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series spans sizes 200 to 600 with ports from 1/8 to 1 in, and options for thread (PT is the standard; G and NPT are orderable), drain type, filter grade (40 um standard, 5 um with the W code), gauge and scale, and bracket. Flow is published as curves rather than a single rating, so we 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. |
| (blank) | Mounting bracket included. |
| 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. |
| (blank) | Filtering grade 40 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.

Drops off a 1 in compressed-air main feeding assembly stations: water and pipe scale are stripped out and the working pressure is held steady for the tools and cylinders downstream.
Conditions the air feeding a large cartoner or palletiser with a 1 in inlet: clean, regulated air to the machine's valve island so actuators cycle at a consistent set point.
Prepares the air supply for quarter-turn pneumatic actuators on large process valves: the filter keeps moisture and debris out of the actuator, and the regulator holds the pressure the actuator was sized for.
Size 600 is the largest GFR frame, with a 1 in port; step down to size 300 or 400 if your line draws less air, and ask us to check the flow curves against your demand before ordering. The manual drain on this unit must be opened periodically, so if the regulator sits where nobody walks past, consider an automatic (A) or differential-pressure drain code instead. The 40 um element is the standard grade; the W code gives 5 um where finer filtration matters. This is the low-pressure regulator type and its exact adjustment range is not published, so confirm it with us for your set point. Thread here is NPT (PT is the catalogue standard; G is also orderable). Mounting bracket included; no gauge fitted, so order a gauge variant if you need a visible set point.
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 G-series flow as curves, not as a single rated figure, so there is no honest one-number answer we can print here. Send us your application's air demand and we will confirm the flow from the datasheet curves before you order.
No. The N in the code means no gauge is fitted. The GFR series is available with an embedded square gauge or an external round gauge in MPa, psi or bar scales, so if you want a visible set point, order a gauge variant or add a gauge separately.
