The AirTAC GFR600C25MJNT AirTAC Filter Regulator 1 in NPT 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 See datasheet ports, a differential-pressure 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 GFR600C25MJNT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This 600-size unit carries a 1 in NPT port for large main lines, a 40 um filter element, and a manual drain that you open by hand to expel collected condensate. The bowl on this size is aluminium alloy. No gauge is fitted with this code, and no mounting bracket is included.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port options from 1/8 in to 1 in, thread options PT, G and NPT, drain choices (differential-pressure, automatic or manual), a 5 um element option, gauge options, and bracket options. Flow is published as curves rather than a single rating, so ask us and we will confirm the datasheet figures for your application 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.

| (blank) | Pressure gauge fitted (blank). |
| (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. |

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 header feeding a production hall, it filters line-scale water and rust out of the compressed air and holds a steady regulated pressure for the whole downstream distribution system.
Mounted ahead of a big air-over-oil press or clamp cylinder circuit, it cleans the incoming air and lets the operator set the working pressure the forming or clamping job requires.
Fitted on the supply line to a heavy-vehicle service bay or a mobile compressor rig, it strips condensate and debris from the air feeding impact tools, lifts and inflation equipment.
Step up through sizes 200, 300, 400 and 600 as your port and air demand grow; this 600 unit with its 1 in NPT port sits at the top of the range for large supply lines. Drain choice matters: manual (this unit) needs someone to open the drain, automatic drains on its own, and differential-pressure drains only while flow is passing. The 40 um element is standard; specify the W code for 5 um where finer filtration is needed. Gauge and scale options exist if you want a visual pressure readout, and PT is the standard thread with G and NPT as order options; this code is the NPT version. Brackets are optional.
Because flow is published as curves and not a single rated figure, 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 the GFR600 as curves rather than a single rated figure, so we do not quote a number. Tell us your line pressure and air demand and we will confirm the datasheet flow figures for this 1 in NPT unit on request.
The M in the code means the drain is opened by hand to let collected condensate out, which suits installations checked daily. If you prefer unattended operation, the same 600 series is available with an automatic drain or the default differential-pressure drain - just ask for the matching code.
