The AirTAC GFR60025MLJC1WTK AirTAC Filter Regulator NPT1 Low-Pressure 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 GFR60025MLJC1WTK is a size-600 filter regulator: water and particulate filtration plus pressure regulation combined in one body, with a 1 in NPT port. This configuration carries the W-code 5 um filter element (finer than the standard 40 um), a manual drain on the bowl, the low-pressure regulator type, a round external pressure gauge scaled in MPa, and a reverse/check valve. The bowl on this size is aluminium alloy. Maximum working (inlet) pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR family is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in PT (standard), G and NPT threads, with differential-pressure, automatic or manual drains, 40 um or 5 um elements, square or round gauges in MPa, psi or bar scales, and a low-pressure regulator option. Flow is published as curves rather than a single rated figure, so we confirm the datasheet and sizing 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. The low-pressure type adjusts over a lower band than standard; we confirm the exact figures from the factory datasheet. 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)). |
| L | Low-pressure type. Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

Feeds filtered, regulated air at a gentle setpoint to the wrap, tuck and seal actuators of a carton or shrink-wrap machine, where the film and linkage work best at reduced line pressure.
Conditions the pilot supply feeding positioners and actuator pilots on big process valves, where a low regulated pressure and clean, dry air keep the pilot circuit stable.
Serves the gate, stopper and divert cylinders that meter bottles between conveyor lanes, where a controlled low pressure prevents product damage at the stops.
Start with the port step: size 600 with a 1 in port suits lines where other branches have already stepped down from larger supply headers; step the size to match the air demand of the circuit rather than oversizing on pipe alone. Because flow is published as curves and not a single rating, ask us to confirm sizing against your application before ordering. Choose the drain to match access: this unit has a manual drain, which needs someone to bleed the bowl on a routine; automatic or differential-pressure drains suit unattended installations. The W code sets the 5 um element; the standard grade is 40 um if your circuit does not need finer filtration. This is the low-pressure (L) regulator type - confirm the exact regulation range for your setpoint with us. Gauge scale is MPa here; psi or bar scales and a square embedded gauge are alternatives. Thread is NPT in this code; PT is the AirTAC standard and G is also available to order. The J code means no mounting bracket is supplied; brackets are optional on other codes.
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, not as a single rated figure, so we do not quote a number here. Send us your application details and we will confirm the flow curve and datasheet figures for this exact 1 in NPT, 5 um, low-pressure configuration on request.
The M code sets a manual drain: the bowl is bled by hand on a routine you set, unlike the automatic or differential-pressure drain options available on other GFR codes. The W code sets the 5 um filter element, one grade finer than the 40 um standard element fitted on codes without W.
