The AirTAC GFR600-25ALJF3T 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 GFR600-25ALJF3T is an AirTAC GFR600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is fitted with a 1 in NPT port, an automatic drain that discharges collected condensate without manual attention, a 40 um standard filter element, and an embedded square gauge scaled in bar. It is the low-pressure regulator type, and the size 600 bowl is aluminium alloy.
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, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (code W) elements, gauge and thread options, and standard or low-pressure regulator types. Flow is published as curves rather than a single rating, so ask us to confirm sizing and datasheet figures 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". |
| 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. |
| J | Supplied without bracket. |
| (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. |
| (blank) | No reverse-flow valve (the default). |
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.

Feeds filtered, regulated air to clamp and fixture cylinders on a CNC machining cell, where clean air and a stable low-pressure set-point protect the clamping sequence.
Supplies the conveyor diverters, stoppers and pusher cylinders on a parcel or distribution line, with the automatic drain handling condensate from a high-flow 1 in supply main.
Conditions and regulates supply air to spray and coating stations on a finishing line, where the low-pressure regulator type and 40 um element keep the process air clean and held at the set-point.
Within the GFR range the real, decodable choices are: size and port (200/300/400/600, 1/8 in to 1 in) stepped against the flow your line needs; drain type - differential-pressure (default), automatic (this model) or manual; filter grade 40 um standard or 5 um with code W; gauge scale MPa, psi or bar; thread PT (standard), G or NPT; and bracket, which this model omits (code J). This unit is the low-pressure regulator type. Flow is published as curves, not a single rating, so 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. Without the K option, air cannot flow back through the unit. A filter regulator adds no oil to the line.
AirTAC publishes flow for this series as curves, not as a single rated figure, so we do not quote a l/min or SCFM number. Send us your application details and we will confirm the flow and datasheet figures for this exact model on request before you order.
The L in the code marks the low-pressure regulator variant of the GFR600; the exact regulation range for this type is not published in the standard table, so we confirm it on request. The A marks an automatic drain, which discharges collected condensate from the aluminium alloy bowl without manual intervention; manual-drain and differential-pressure-drain versions are available in the same series.
