The AirTAC GFR60025MJNTK 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 manual drain and regulates 0.05 - 0.9 MPa (7 - 130 psi). It does not lubricate — add a GL lubricator, or order the GFC two-unit set, if downstream equipment needs oil.
The AirTAC GFR60025MJNTK is a size-600 filter regulator that combines two jobs in one body: it removes water and particulate from compressed air through a 40 um element, and it regulates downstream pressure over a 0.05-0.9 MPa (7-130 psi) adjustment range. This configuration is threaded NPT1 (1 in), uses a manual drain on the bowl, and carries a built-in reverse (check) valve so downstream pressure is held if the upstream supply drops. No gauge is fitted as supplied, and the size-600 bowl is aluminium alloy.
This is a genuine AirTAC part from the GFR series, which spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional 5 um filtration (code W), automatic, manual or differential-pressure drains, and optional gauges. Flow figures for this series are published as curves rather than a single rating, so ask us to confirm sizing and datasheet details 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 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". |
| M | Drain: Manual drain — this also sets the regulating band (0.05 - 0.9 MPa (7 - 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 on the 1 in main drop feeding a machining cell, the GFR60025MJNTK strips water and chips of particulate out of the supply and holds a set downstream pressure to the machine's air valves, with the check valve holding the circuit if the header is isolated.
Mounted ahead of the air distribution to a powder-coating booth, this filter regulator cleans the compressed air feeding the spray equipment and lets the line set a stable working pressure for consistent coating application.
On a packaging line, the unit feeds a conveyor section's pneumatic actuators with cleaned air at a set pressure, and the manual drain lets maintenance bleed accumulated condensate during scheduled walk-rounds.
Choose the size step by the flow your line needs: 200, 300, 400 and 600 move progressively more air through progressively larger ports, and this unit sits at the top of the range with a 1 in NPT thread. On drain type, manual suits installations where someone walks the line and bleeds the bowl; automatic or differential-pressure drains suit unattended positions. The standard element is 40 um; specify code W for 5 um where finer particulate removal matters. Gauges (square embedded or round external, in MPa, psi or bar scales) are optional and not fitted on this code. PT is the standard thread; G (BSPP) and NPT are catalogue options to order. Brackets are optional on GFR.
One honest note on sizing: AirTAC publishes flow for this series as curves, not as a single rated figure, so send us your application details and we will confirm the right size against the datasheet before you order.
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 there is no one rated flow number we can quote. Send us your application details and we will confirm the flow data from the datasheet so you can size the unit correctly before ordering.
The M in the code GFR60025MJNTK specifies a manual drain: condensate in the bowl is bled by hand, which suits attended installations. If the unit will sit unattended, the GFR series is also available with an automatic drain (code A) or a differential-pressure drain (blank), which drains without operator action.
