The AirTAC GFR60025ALJNT AirTAC Filter Regulator, NPT1, Auto Drain 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 GFR60025ALJNT is an AirTAC GFR600 filter regulator: filtration and pressure regulation combined in one body. It removes water and particulate from compressed air with the standard 40 um element, then regulates downstream pressure with the low-pressure type regulator. This configuration has an automatic drain that ejects collected condensate without manual attention, a 1 in NPT port, and no gauge fitted. The size 600 bowl is aluminium alloy, and the unit carries no mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with a choice of ports, threads, drains, filter grades and gauge options, so a variant can be matched to most supply lines. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet and sizing 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. |
| (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.

Filtering and regulating the air feeding clamp and fixture cylinders on a CNC machining cell, with the automatic drain keeping condensate out of the clamping circuit during long unattended runs.
Conditioning the air that drives pick-and-place and sealing actuators on a packaging line, where the 40 um element protects valve spools and the low-pressure regulator suits lower set-point circuits.
Supplying filtered, regulated air to blow-off nozzles that clear dust and debris from product or belts on a conveyor line, with the automatic drain handling moisture without operator intervention.
Start with the port step: this unit is size 600 with a 1 in NPT port, the largest in the GFR range, so size up or down (200/300/400/600) according to the air demand of the line. Drain choice matters: automatic (this unit) drains condensate by itself, manual requires operator action, and differential-pressure draining is the catalogue default. Filter grade is 40 um standard; specify code W for the 5 um element where finer filtration is needed. This is the low-pressure type regulator, so confirm its exact regulation range with us before ordering if your set point is critical. No gauge is fitted; gauge and scale options exist on other variants. Thread is NPT here; PT is the standard and G (BSPP) is an order option. Bracket: not included on this variant (code J).
Because flow is published as curves and not as a single rating, send us your application details and we will confirm sizing against the datasheet before you order.
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 family as curves rather than a single rated figure, so we do not quote a number. Tell us your line demand and application and we will confirm the sizing against the datasheet on request before you order.
The code ends its gauge position with N, so no pressure gauge is supplied; gauge options with different scales exist on other GFR variants. The L in the code marks the low-pressure type regulator, whose exact regulation range is not published in our sheet, so confirm the range with us if your set point is critical.
