The AirTAC GFR60020MLJF1WT AirTAC Filter Regulator 3/4 in NPT 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 PT3/4" 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 GFR60020MLJF1WT is an AirTAC GFR-series filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in a single body. This size 600 unit is built with a 3/4 in NPT port, a 5 um filter element (the finer of the two catalogue grades), a manual drain on the aluminium alloy bowl, and a fitted embedded square gauge reading in MPa. It is the low-pressure type, intended where the regulated output must sit below the standard regulator's range, and it is supplied without a mounting bracket.
This is a genuine AirTAC part. The GFR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, a choice of 40 um or 5 um filtration, differential-pressure, automatic or manual drains, and gauge options. 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 sizing or any datasheet figure for your application before ordering.

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.

|---|---|
| 20 | Port size PT3/4". 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. |

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.

Feeding clean, regulated air to the clamp cylinders on a CNC machining cell, where the 5 um element helps keep fine particles out of the clamping valves and the low-pressure regulator holds the clamp circuit at its set pressure.
Supplying filtered, regulated air to diaphragm or piston actuators on process control valves in a plant room, with the square MPa gauge giving the operator a direct read of the supply pressure at the valve.
Conditioning the air feeding the pick-and-place and sealing cylinders on a packaging line, where water and particulate removal plus stable low-pressure regulation keep the motion consistent through the shift.
Size 600 with a 3/4 in port is the largest step in the GFR range, so start there when the line serving the unit is 3/4 in or when the flow demand sits above what smaller ports handle; step down to 300 or 400 if the pipe is smaller. This unit carries the 5 um element (code W) rather than the 40 um standard, which suits downstream equipment that is sensitive to finer particles. The manual drain means someone opens the bowl drain during checks rather than relying on an automatic or differential-pressure mechanism - choose this only where a maintenance walk-past is practical. The low-pressure type regulator is selected where the working output is well below standard ranges; the exact adjustment window for the low-pressure type is not published in our sheet, so confirm it with us. The fitted square gauge reads MPa; external round gauges with psi or bar scales are available as options. The port here is NPT; PT is the catalogue standard and G (BSPP) is also orderable. A mounting bracket is not included with this code.
Because flow is published only as curves and not as a single rated figure, send us your application's flow and pressure requirements and we will confirm the correct size 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 this family as curves rather than a single rated figure, so we do not quote a l/min, m3/h or SCFM number. Send us your required flow and working pressure and we will confirm against the datasheet whether this size 600, 3/4 in unit suits your application before you order.
The M in the code means the aluminium alloy bowl is drained by hand: an operator opens the drain during routine checks instead of the bowl discharging automatically. The W in the code means the element is the 5 um grade rather than the 40 um standard, so finer particulate is caught upstream of your regulator output - useful for sensitive valves and actuators, at the cost of checking the drain and element more often.
