The AirTAC GFR60025ALJNTK AirTAC 1 in NPT Filter Regulator 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 GFR60025ALJNTK is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is fitted with a 1 in NPT port, a 40 um standard filter element, an automatic drain that ejects collected condensate without manual attention, and a reverse/check valve that holds the downstream circuit when upstream supply is lost. It is the low-pressure type and comes without a gauge or mounting bracket. The aluminium alloy bowl suits the large size-600 body.
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of PT (standard), G or NPT thread, differential-pressure, automatic or manual drains, a 40 um standard or 5 um (W) filter element, and gauge options. Flow is published as curves rather than a single rated figure, 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. |
| 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. |
| (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.

Feeds big-bore actuator circuits on process valves where air is filtered and held at a steady reduced pressure, with the check valve keeping the actuator position stable if upstream supply drops.
Serves as the point-of-use filter regulator on a 1 in plant air drop feeding multiple workstations, with the automatic drain clearing condensate on a high-volume main without operator attention.
Placed ahead of a packaging machine's manifold, it strips water and particles from the plant supply and regulates pressure to the machine's low-pressure requirement in one compact unit.
Size 600 with a 1 in port is the largest step in the GFR range - choose it when your line's air demand calls for the biggest port and flow capacity, and step down to 200/300/400 for lighter duty. Drain choice matters here: the automatic drain on this model suits unattended or high-condensate duty, while manual and differential-pressure drains are the alternatives. Filter grade is the 40 um standard element; specify the 5 um (W) option only where downstream equipment needs finer filtration. This unit is the low-pressure type, has no gauge fitted (a gauge can be specified on other configurations), includes a reverse/check valve, and omits the mounting bracket. Thread is NPT; PT is the catalogue standard and G is also orderable.
Because flow is published as curves and 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 one number. Tell us your application and we will confirm the flow figures from the datasheet on request before you order.
The N in the code means no gauge is fitted on this configuration; gauge options are available on other GFR codes. The K means a reverse/check valve is fitted, which holds downstream pressure if the upstream supply is interrupted. The L marks it as the low-pressure regulator type.
