The AirTAC GFR60025ALF2TK 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 AirTAC GFR60025ALF2TK is a filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size-600 unit carries a 1 in NPT port, an automatic drain that discharges collected condensate without manual attention, a 40 um standard filter element, and the low-pressure regulator type. An embedded square gauge reading in psi is fitted, a reverse/check valve is built in, and the aluminium alloy bowl matches this largest frame in the series.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with ports from 1/8 in to 1 in, PT as the standard thread and G or NPT as order options, a choice of automatic, manual or differential-pressure drains, 40 um standard or 5 um (W) elements, and MPa, psi or bar gauge scales. Flow is published as curves rather than a single rating, so 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.
| GFR600 | G-series filter regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| 2 | Gauge scale: psi. 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.

Supplying filtered, regulated air to case-sealing and taping heads along a packaging conveyor, with the automatic drain keeping condensate out of the sealing valves.
Feeding grip and lift cylinders on a bottling line where water carry-over must be drained automatically and downstream pressure held steady at modest settings.
Regulating air to pneumatic clamps and swing cylinders on machining fixtures, with the 40 um element protecting directional valves from particulate.
Step the size (200/300/400/600) up against the flow your line needs - larger frames carry larger ports, and this code sits at the top with a 1 in NPT connection. Pick the drain: automatic (this unit) for unattended condensate discharge, manual for periodic servicing, or differential-pressure as the catalogue default. The element is 40 um standard; specify W for the 5 um grade where finer filtration is required. The embedded square gauge here reads psi, with MPa and bar scales available as alternatives. Thread is NPT on this code; PT is the standard and G (BSPP) is orderable. A mounting bracket is included. Because 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 flow for the GFR series as curves rather than a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the datasheet flow figures and sizing for this 1 in NPT unit on request.
The L marks the low-pressure regulator type. The exact regulation range for this variant is not published in the standard tables, so we confirm it on request against your setpoint. The maximum inlet pressure remains 1.0 MPa (145 psi), and the unit operates from -5 to 70 C (non-freezing).
