The AirTAC GFR60025MLJF1WTK AirTAC 1 in NPT Filter Regulator 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 GFR series combines water and particulate filtration with pressure regulation in a single body. This GFR60025MLJF1WTK is the size 600 unit with a 1 in NPT port, a 5 um filter element (code W), a manual drain, and the low-pressure regulator type. The size 600 bowl is aluminium alloy, a square pressure gauge scaled in MPa is fitted, and a reverse (check) valve is built in. No mounting bracket is fitted.
This is a genuine AirTAC part. The GFR filter-regulator family spans sizes 200, 300, 400 and 600 with ports from 1/8 in to 1 in, PT as standard thread and G or NPT as order options, plus a choice of drain type, filter grade and gauge. Maximum inlet pressure is 1.0 MPa (145 psi) and the working temperature range is -5 to 70 C, non-freezing. Flow is published as curves rather than a single rating, so ask us to confirm 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. |
| 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 spray guns in a refinishing booth with air stripped of water and fine particles and held at the low, steady pressure the gun needs.
Supplies filtered, regulated air to fixture clamps on a machining centre, with the built-in check valve guarding the circuit against backflow.
Cleans and regulates air to cylinder-driven gating and diverting actuators on a bottling conveyor, with the manual drain cleared at shift checks.
Size and port set the air capacity: this unit is size 600 with a 1 in NPT port, the largest step in the GFR range, so match it to the flow your line needs. Drain choice matters: manual (fitted here) means an operator opens the drain to release condensate, while automatic and differential-pressure drains discharge without attention. Filter grade is 40 um standard or 5 um (code W, fitted here) for finer protection. Gauge scale can be MPa, psi or bar; this unit carries a square gauge in MPa. Thread is PT as standard with G and NPT as catalogue options, and brackets are optional (not fitted on this code). Flow is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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 rather than a single rated figure, so we do not quote a number here. Tell us your application and we will confirm the flow and datasheet figures for this exact model on request.
This model carries code M, a manual drain: an operator opens the drain to release collected condensate. The GFR family is also available with automatic or differential-pressure drains - ask for the alternative model code when ordering.
