The AirTAC GFR60025MLJF1TK AirTAC Filter Regulator NPT1 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 series combines water and particulate filtration with pressure regulation in a single filter-regulator body. This unit, GFR60025MLJF1TK, is the size-600 configuration with a 1 in NPT port, a manual drain, the standard 40 um filter element, the low-pressure regulator type, an embedded square gauge with MPa scale, and a fitted reverse/check valve. The bowl at size 600 is aluminium alloy, and this configuration is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, drain choices (differential-pressure, automatic or manual), 40 um standard or 5 um (W) elements, gauge and scale options, and PT, G or NPT threads. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature is -5 to 70 C, non-freezing. Flow for this family is published as curves rather than a single rated figure, so ask us to confirm sizing and datasheet figures 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. 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). |
| F | Gauge shape: Square. C is round, F is square. |
| 1 | Gauge scale: MPa. 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.

On a carton-forming line, this unit filters water and particles from the shop air supply and regulates it down to the reduced pressure the sealing and clamping cylinders need, with the manual drain emptied during scheduled checks.
On a water-treatment or chemical skid, positioners and diaphragm actuators depend on clean, regulated air at reduced pressure. This low-pressure-type filter regulator conditions the pilot supply, with the 1 in NPT port matching the main air line.
At a machining-cell air drop, the unit removes condensate and particulate from the header supply and holds a steady low regulated pressure for air tools and clamping fixtures, with the aluminium bowl drained by hand at shift end.
Size and port step up together: 200 through 600, with ports from 1/8 in to 1 in. This unit sits at the top of the range with a 1 in NPT port, so check the port against your piping and the size against your flow demand. Drain type is a maintenance choice: the manual drain on this unit is emptied by hand on a schedule, while automatic and differential-pressure drain variants in the series need no manual attention. The element is 40 um standard; specify W for the 5 um grade where finer filtration is needed. Gauge scale (MPa, psi or bar), thread (PT is the standard, G and NPT are catalogue options) and the bracket are all decodable choices.
Flow for this family is published as curves, not as a single rated number, so no rated flow is quoted here. Send us your application conditions and we will confirm sizing and the datasheet figures on request 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 GFR600 series as curves, not as a single rated figure, so we do not quote a rated flow, Cv or SCFM here. Send us your application conditions and we will confirm the sizing and the datasheet figures on request before you order.
The L code marks the low-pressure regulator variant of the GFR600 filter regulator. Its exact adjustment range is not published in the material we hold, so we confirm the range from the AirTAC datasheet on request; the standard-type variants carry their own published ranges.
