The AirTAC GFR60025ALJNWT AirTAC Filter Regulator NPT1 Low-Pressure is a genuine G-series filter regulator: water separation, 5 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 GFR60025ALJNWT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single compact body. This size-600 unit has a 1 in NPT port, an automatic drain that discharges collected condensate without manual attention, a fine 5 um filter element, and the low-pressure regulator type for applications that operate at reduced pressure. The aluminium alloy bowl suits the larger 600 frame, and no gauge is fitted, so add an external gauge separately if a pressure indication is needed at the unit.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, standard or low-pressure regulation, differential-pressure, automatic or manual drains, and a 40 um standard or 5 um (W) element. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and flow 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. |
| 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. |
| W | Filtering grade 5 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, low-pressure regulated air to paint spray guns in a finishing booth; the 5 um element helps keep moisture and particulate out of the air line ahead of the gun.
Supplies the low-pressure air that closes and holds heat-seal cylinders and clamps on a carton or bag sealing line, with automatic condensate draining between shifts.
Conditions and regulates supply air for low-pressure pneumatic instruments and actuators on a process skid, where fine 5 um filtration protects sensitive control components.
Size 600 with a 1 in NPT port is the largest GFR frame, so step up to it when your line's flow demand outgrows the 300/400 units - match the published flow curve to your consumption rather than guessing. Choose the automatic drain where condensate collection is continuous or the unit is mounted where nobody walks past to drain it; manual or differential-pressure drains are the alternatives in the family. The 5 um element here is the finer of the two published grades (40 um is standard), for downstream equipment that tolerates less particulate. This is the low-pressure regulator type; its exact adjustment range is not published, so confirm it against your working pressure with us first. No gauge or bracket is fitted with this code, and NPT is the ordered thread option (PT is the catalogue standard; G/BSPP is also available) - tell us which you need when 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 the GFR series as curves, not as a single rated number, so there is no one figure we can honestly quote. We can confirm the flow curve and datasheet for this 1 in NPT size-600 unit against your application's air consumption - just ask before ordering.
In the code GFR60025ALJNWT, the A position selects the automatic drain, which discharges collected condensate on its own instead of waiting for a manual drain; the N position means no gauge is fitted. If you want a pressure indication at the unit, an external gauge can be added separately - tell us when ordering.
