The AirTAC GFR60025AJNTK AirTAC Filter Regulator NPT1 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 GFR60025AJNTK is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit has a 1 in NPT port, a 40 um standard filter element, an automatic drain that expels collected condensate without manual attention, and a reverse/check valve fitted. No gauge is supplied with this configuration, and it comes without a mounting bracket.
This is a genuine AirTAC part in the largest GFR size, which is also available in 200, 300 and 400 with a choice of ports, drain types, a 5 um (W) element option, gauge options and PT or G threads. The aluminium alloy bowl is standard at size 600. Rated flow is published as curves rather than a single figure, so we confirm the datasheet and flow figures on request.

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.
| 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)). |
| (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. |
| (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.

Installed at a 1 in branch off the compressor ring main to remove condensate and set a stable working pressure for a production hall's air supply.
Feeding large-bore cylinders and air-operated gates on a packaging or palletising conveyor line, where the automatic drain keeps the bowl clear during continuous shifts.
Used as the conditioning and regulation point ahead of a manifold feeding several machines, with the reverse/check valve holding downstream pressure if supply dips.
Choose the size and port step against the air demand of the line: this unit is size 600 with a 1 in NPT port, the largest step in the range. The 40 um element suits general supply-air protection; specify the 5 um W option when finer filtration is needed. The automatic drain suits unattended or hard-to-reach installations; manual and differential-pressure drains are alternatives in other configurations. Because published flow data is given as curves rather than 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 GFR flow performance as curves, not as a single rated figure, so we do not quote a number here. Ask us and we will confirm the datasheet and flow curve for this 1 in NPT size 600 unit against your application before you order.
The N in the code means no gauge is supplied with this configuration. Other GFR600 configurations include an embedded square gauge or an external round gauge with MPa, psi or bar scales - ask us to quote the variant that suits your panel.
