The AirTAC GFR60025MLF3TK 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 GFR60025MLF3TK 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 built around a 1 in NPT port, a manual-drain bowl in aluminium alloy, a 40 um standard filter element, and a low-pressure regulator. It includes the embedded square gauge scaled in bar, a reverse/check valve already fitted, and the mounting bracket. 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 family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, and options that include automatic, manual or differential-pressure drainage, a 5 um element (code W), an external round gauge with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow for this size is published as curves rather than a single rating, so ask us to confirm the figures against your application and we will send the datasheet.

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.

| 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. |
| (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.

On a low-pressure spray line, the unit strips water and scale from the compressed-air feed and holds the atomising pressure steady at the booth manifold, with the bar-scaled gauge giving the operator a direct reading.
Air-jet weaving runs on large-volume, modest-pressure air; a 1 in filter regulator conditions the main header feed and keeps jet pressure stable across the loom bank.
At a container rinse and blow-off point, the manual-drain bowl lets maintenance vent collected water at each shift check, while the regulator sets the blow-off pressure for containers and conveyors.
Choose the size by the port and flow your line needs: this unit is size 600 with a 1 in NPT port, the largest step in the range. The manual drain means an operator opens the bowl drain during checks - pick automatic (A) or differential-pressure (blank) drainage if you cannot schedule that. The 40 um element is the standard grade; a 5 um element (code W) is available when finer filtration is required. The embedded square gauge reads in bar, and round external gauges with MPa, psi or bar scales can be ordered. Threads are PT as standard with G and NPT as catalogue options, and the bracket is included while a no-bracket version (code J) exists in the family. Because flow is published as curves rather than a single rating, ask us to confirm sizing against your application before ordering.
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 GFR600 as curves rather than a single rated figure, so we do not quote a number here. Tell us your line pressure and air demand and we will confirm the sizing from the datasheet on request.
The M in the code selects a manual drain: an operator opens the bowl drain to release collected water. If you cannot schedule that, the same size is available with automatic (A) or differential-pressure (blank) drainage. This unit also carries the low-pressure regulator type, a square gauge scaled in bar and a reverse/check valve, all decodable from the code.
