The AirTAC GFR60025ALF3TK AirTAC Filter Regulator 1 in NPT 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 automatic drain and regulates 0.15 - 0.9 MPa (20 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The GFR60025ALF3TK 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 for a 1 in NPT port, with an automatic drain that expels collected condensate without manual attention, a 40 um standard filter element, the low-pressure regulator type, an embedded square gauge scaled in bar, and a reverse/check valve fitted. Maximum inlet pressure is 1.0 MPa (145 psi), the working temperature range is -5 to 70 C (non-freezing), the 600-size bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, plus drain choices (differential-pressure, automatic or manual), an optional 5 um element (code W), gauge and thread options, so a matching unit can be specified for most lines. Flow is published as curves rather than a single rating; ask us to confirm the 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.

|---|---|
| 25 | Port size PT1". This body offers 20 = PT3/4", 25 = PT1". |
| A | Drain: Automatic drain — this also sets the regulating band (0.15 - 0.9 MPa (20 - 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.

Filtering and regulating the air feed to spray-booth drops, where clean, low-pressure air protects finish quality and the automatic drain keeps collected condensate away from the guns.
Supplying filtered, regulated air to the cylinders and actuators that drive a packaging conveyor's clamps and diverters, with the fitted check valve holding downstream pressure if the supply dips.
Feeding air to quarter-turn actuated valves on a process skid, where the 1 in port matches the main header and the bar-scaled square gauge lets technicians set and verify actuator supply pressure.
Size and port step up with flow demand: 200, 300, 400 and 600 sizes cover ports from 1/8 to 1 in, and this unit is the 600 size on a 1 in NPT port. Drain choice is differential-pressure (the default), automatic (this unit) or manual. Filter grade is 40 um standard or 5 um with code W. The embedded square gauge is standard and this one is scaled in bar (MPa and psi scales are available); an external round gauge is optional. Thread: PT is the standard, with G and NPT as order options - this unit is ordered in NPT. A bracket is included here; J codes omit it. The regulator in this unit is the low-pressure type, and its exact range is not published, so confirm it with us. Flow is published as curves, not 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 GFR flow as curves, not a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and datasheet figures for this unit before you order.
This unit carries code A: an automatic drain expels collected condensate without anyone opening the bowl. The GFR family also offers manual drain (code M) and differential-pressure drain (the default, blank code) - tell us which suits your maintenance routine and we will match the code.
