The AirTAC AirTAC GFR60025AJNWT Filter Regulator 1 in NPT, 5 um 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 AirTAC GFR600 is a filter regulator: it removes water and particulate from compressed air and holds downstream pressure at your set point in a single body. This unit is the 600 size with a 1 in NPT port, an automatic drain that ejects collected condensate without manual attention, and the 5 um filter element (code W) for finer filtration than the standard 40 um element. At size 600 the bowl is aluminium alloy. No gauge is fitted and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, manual, automatic or differential-pressure drains, 40 um or 5 um elements, gauge options, and G or NPT thread variants. Maximum inlet pressure is 1.0 MPa (145 psi); with the automatic drain fitted, the standard regulator adjusts from 0.15 to 0.9 MPa (20-130 psi), and operating temperature is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm sizing and 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. Standard type, regulating 0.15 - 0.9 MPa (20 - 130 psi). 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.

|---|---|
| 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)). |
| (blank) | Standard 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. |

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.

Feeding a 1 in main line that supplies impact wrenches, weld-clamp actuators and air guns across a body shop: the GFR600 strips water and swarf from the main supply and holds a steady set pressure so tools behave consistently from the first station to the last. The automatic drain keeps condensate off the circuit at an unmanned drop point.
On a carton-forming and closing line, clamp and press cylinders need one stable pressure regardless of upstream compressor swing. This unit filters the supply to 5 um to protect valve spools and cylinder seals, and regulates the circuit pressure so sealing force stays repeatable through every shift.
Conveyor diverters, stopper cylinders and gate actuators on a bottling line run off a filtered, regulated branch. The 1 in NPT port serves the branch header, the 5 um element keeps grit out of the divertor valves, and the automatic drain handles the condensate that collects where nobody opens a bowl by hand.
Size and port are the first choice: this is the largest GFR size, with a 1 in NPT port intended for high-flow main lines, so step down to size 200-400 if your circuit draws less air. Drain type is a real operating decision: the automatic drain here suits unmanned or hard-to-reach points, while manual and differential-pressure drains are orderable alternatives in the same family. The 5 um element (code W) is the finer option over the standard 40 um - choose it where downstream equipment is more sensitive to particulate. Thread is NPT on this unit; PT is the standard and G (BSPP) is orderable. A mounting bracket and a gauge (embedded square, or external round with MPa, psi or bar scales) can be specified on related codes. Flow is published as curves, not a single rated figure, so send us your flow and pressure requirements and we will confirm sizing from 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 G-series flow as curves rather than a single rated figure, so we do not quote a flow number here. Send us your required flow and working pressure and we will confirm sizing from the datasheet on request before you order.
Code A fits the automatic drain, which ejects collected condensate without daily attention - useful at unmanned or hard-to-reach points. The same GFR600 body is orderable with a manual drain (M) or the differential-pressure default. Note the regulator range changes with drain type: 0.15-0.9 MPa (20-130 psi) with automatic or differential-pressure drain, and 0.05-0.9 MPa (7-130 psi) with a manual drain.
