The AirTAC GFR60025MLJNT AirTAC Filter Regulator NPT 1 in Low-Pressure 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 GFR600 is a size-600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This configuration is built with a 1 in NPT port, a manual drain on the bowl, the standard 40 um filter element, the low-pressure regulator type, and no gauge fitted. The manual drain means an operator opens the drain at the bottom of the bowl to expel collected condensate, which suits installations visited on a routine schedule. Because this is the 600 size, the bowl is aluminium alloy, and the maximum working (inlet) pressure is 1.0 MPa (145 psi) with an operating temperature of -5 to 70 C, non-freezing.
This is a genuine AirTAC part. The GFR line is available in sizes 200, 300, 400 and 600, with port options, a 5 um filter element (code W), automatic or differential-pressure drain alternatives, gauge choices, and a bracket option depending on the code. Flow is published by AirTAC as curves rather than a single rated figure, 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. 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. |
| 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. |
| (blank) | No reverse-flow valve (the default). |
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 main plant air header, it filters water and scale out of the supply and holds a reduced, stable pressure for a process that cannot tolerate full header pressure. The manual drain suits a header walked by operators on a fixed round.
Placed upstream of big-bore directional valves and cylinders on a packaging or material-handling line, it keeps pipe rust and condensate out of the valve seats while setting the pressure the actuator circuit was designed around.
Feeding air to a blasting cabinet or coating station where the process runs at reduced pressure, the 40 um element stops particulate reaching the gun while the regulator lets the operator set the working pressure at the cell rather than at the compressor room.
Sizing a GFR starts with the port and size step: 200, 300, 400 and 600 cover ports from 1/8 in up to 1 in, and the larger the size the larger the port and the greater the flow path, so match the step against the air demand of the circuit. From there the real choices are: drain type (manual here; automatic or differential-pressure are alternative codes), filter grade (40 um standard, 5 um with code W for finer particulate), gauge and scale if you want a fitted gauge, thread family (PT is the AirTAC standard; G/BSPP and NPT are order options, as on this unit), and whether a mounting bracket is included.
One honest note before you order: AirTAC publishes flow as curves, not as a single rated number, and the exact adjustment range of the low-pressure type is not stated in the material we hold. Send us your line pressure, required set pressure and air demand, and we will confirm sizing against the datasheet before you commit.
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 GFR series as curves, not as a single rated figure, so we do not quote a number on the page. Tell us your port size, upstream pressure and air demand, and we will confirm the relevant datasheet curve and sizing for your application on request.
The L in the code marks the low-pressure regulator type, intended for reduced set pressures below the standard range; the exact adjustment range for this type is not published in our material, so we confirm it on request. The N in the code means no gauge is fitted - a gauge (square or round, with MPa, psi or bar scale) is available as a different code, and the 1 in NPT thread is itself an order option alongside the PT standard and G/BSPP.
