The AirTAC GFR600-20MLJF2T AirTAC Low-Pressure Filter Regulator NPT3/4 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 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 AirTAC GFR600-20MLJF2T is a filter regulator: water and particulate removal plus pressure regulation combined in a single 600-size body. This configuration carries a 3/4 in NPT port, a 40 um standard filter element, a manual drain on the bowl, and the low-pressure regulator type for circuits that run at reduced supply pressure. The bowl on this 600 size is aluminium alloy, and an embedded square gauge with a psi scale is fitted so the set pressure is readable at the unit.
This is a genuine AirTAC part. The GFR family is published in 200, 300, 400 and 600 sizes with a choice of ports and threads, manual, automatic or differential-pressure drains, a 5 um (W) element option, and gauge scale choices, so a matching unit can be specified for most lines. Flow figures are published as curves rather than a single rating; 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. |
|---|---|
| 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. |
| 2 | Gauge scale: psi. 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.

Settle a filtered, regulated supply at the drop feeding a carton-forming and case-sealing line: the 40 um element strips water and pipe scale from the main header, while the low-pressure regulator holds a gentle, stable setting for the line's air cylinders and actuators.
Condition the bench air feed to a pilot rig or test station where the process calls for reduced supply pressure: the low-pressure regulator type suits circuits that run well below full line pressure, and the psi-scale gauge lets an operator read and repeat the setting.
Feed the air knives, blow-off nozzles and take-up cylinders on a conveyor or palletising line: the combined body conditions the air and regulates it in one mounting, and the manual drain suits a location where an operator walks the line on a fixed schedule.
Size up by port and flow: the 600 size with its 3/4 in NPT port is the largest step in the GFR range, so use it where a line needs more air than a 300 or 400 unit supplies. Choose the drain to suit access: manual drain (as here) needs someone to open it at intervals, automatic drains themselves, and differential-pressure drain reacts to element loading. The 40 um element is the standard grade; specify 5 um (code W) where finer particulate removal matters. The fitted square gauge reads in psi; MPa and bar scales are also available. PT is the standard thread and G (BSPP) or NPT are order options, and brackets are optional - this unit is ordered without one.
One honest note before ordering: AirTAC publishes flow for this family as curves, not as a single rated figure, so send us your flow and pressure requirements 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 family as curves rather than as a single rated figure, so there is no one rated flow number we can quote honestly. Send us your required flow and working pressure and we will confirm the figures from the datasheet for this exact 600-size, 3/4 in NPT unit on request.
The M in the code selects a manual drain: someone opens the bowl drain at intervals to remove collected water. If the unit will be mounted where it cannot be serviced regularly, the same GFR600 body can be ordered with an automatic drain (code A) or a differential-pressure drain (blank), which drain themselves instead.
