The AirTAC GFR60025ALNWT 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 GFR60025ALNWT is an AirTAC GFR-series filter regulator: one body that removes water and particulate from compressed air and regulates downstream pressure. This size-600 unit is specified with a 1 in NPT port for high-flow supply lines, an automatic drain that expels collected condensate without manual attention, and the W-code 5 um filter element for finer filtration than the standard 40 um grade. It is the low-pressure (L) type, and no gauge is fitted (N code), so a separate gauge must be added if local pressure indication is required.
This is a genuine AirTAC part from the GFR range, which spans sizes 200 to 600 with port options from 1/8 in to 1 in, a choice of automatic, manual or differential-pressure drains, 40 um or 5 um filter grades, and PT, G or NPT threads. Flow is published as curves rather than a single rated figure, so we confirm datasheet and flow figures on request before you order.

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. |
| 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.

Installed at the take-off from a large plant air header to clean the supply and hold a steady low downstream pressure for an entire production bay.
Feeding filtered, regulated air to carton-forming and case-sealing cylinders on a high-volume packaging conveyor, with the automatic drain handling condensate around the clock.
Supplying multi-point air-blow and part-cleaning stations where 5 um filtration protects nozzles from particulate and the low-pressure type matches gentle blowing requirements.
Size 600 with a 1 in port is the largest step in the GFR range; size up or down (200/300/400/600) according to the flow your line needs, and confirm the match against the published flow curve with us before ordering. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are available if you prefer scheduled or load-dependent draining. The 5 um (W) element is the finer option versus the 40 um standard grade. Thread here is NPT; PT is the standard and G (BSPP) is also an order option. A mounting bracket is included. No gauge is fitted with the N code, and the exact regulation range of the low-pressure type is not published, so ask us to confirm both against your application.
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 figure, so we do not quote a number. Send us your line pressure and air demand and we will confirm the flow and datasheet figures for this exact model on request before you order.
The N code in GFR60025ALNWT means no gauge is supplied, so add a separate gauge if you need local pressure indication. The L code marks the low-pressure type of the GFR regulator; its exact adjustment range is not published in our sheet, so ask us to confirm it for your setpoint.
