The AirTAC GFR60025MJNWTK AirTAC Filter Regulator NPT 1 in 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 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 GFR60025MJNWTK is a size-600 filter regulator that removes water and particulate from compressed air and regulates downstream pressure in a single body. It is supplied with a 5 um filter element, a manual drain bowl, a reverse/check valve fitted, and no gauge, with NPT 1 in ports. The manual drain lets you bleed accumulated condensate by hand as part of a routine check, and the check valve holds the downstream setting if upstream supply is interrupted.
This is a genuine AirTAC part. The GFR family spans sizes 200 to 600 with port sizes from 1/8 in to 1 in, optional 40 um or 5 um elements, differential-pressure, automatic or manual drains, and gauge or no-gauge configurations. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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 0.05 - 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. |
| 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. |
| 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.

A 1 in filtered and regulated drop feeding pneumatic impact tools and clamping fixtures on an automotive trim line, with the 5 um element protecting downstream valves from fine particulate.
Conditioning the main air supply to conveyor pushers and stopper cylinders in a bottling plant, where the regulator holds a steady setting and the check valve guards against supply dips.
Filtered, regulated air to actuated valves on a pilot-scale chemical process skid, where the manual drain suits a supervised installation and the 5 um grade supports clean instrument air.
This unit is the large end of the GFR range: size 600 with 1 in NPT ports, chosen when the air demand at the point of use calls for the biggest port step in the family. The 5 um element (code W) suits applications that need finer particulate capture than the 40 um standard. The manual drain (code M) is the right choice when someone is already attending the unit regularly; an automatic drain removes that task if preferred. Regulation range with manual drain is 0.05-0.9 MPa (7-130 psi). No gauge is fitted (code N), so add a separate gauge if a visual pressure reading is needed at the unit.
Flow through the GFR600 is published as curves, not a single rated number, so send us your flow and pressure requirements and we will confirm sizing against the datasheet before you order. Thread is NPT here; PT is the standard and G (BSPP) is also a catalogue option.
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 GFR600 flow as curves rather than a single rated figure, so no one number is quoted here. Send us your required flow and working pressure and we will confirm sizing and the datasheet figures on request before you order.
The code MJN decodes as manual drain (M), no bracket (J) and no gauge (N). A manual drain means condensate is bled by hand during routine checks; automatic and differential-pressure drains are available on other variants. With no gauge fitted, add a separate gauge if you need a pressure reading at the unit. This variant also carries a 5 um element (code W) and a reverse/check valve (code K).
