The AirTAC GFR60020MF3WT AirTAC Filter Regulator NPT3/4, 5 um 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 GFR60020MF3WT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. This configuration has a 3/4 in NPT thread, a 5 um filter element, a manual drain on the bowl, an embedded square gauge reading in bar, and a standard regulator with an adjustment range of 0.05-0.9 MPa (7-130 psi). Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), the 600-size bowl is aluminium alloy, and a mounting bracket is included.
This is a genuine AirTAC part. The GFR family is made in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options across the family include automatic or manual drains, a 40 um or 5 um element, G (BSPP) or NPT threads in addition to the PT standard, gauge scale choices and bracket variants. Flow is published as curves rather than a single rated figure, so ask us to confirm the 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. Standard type, regulating 0.05 - 0.9 MPa (7 - 130 psi). 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)). |
| (blank) | Standard type. Blank is standard, L is the low-pressure type. |
| (blank) | Mounting bracket included. |
| (blank) | Pressure gauge fitted (blank). |
| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 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.

Filters and regulates the 3/4 in shop-air feed to a CNC machining centre, removing water and particles before machine valves and actuators while holding the supply at the pressure the machine builder specifies.
Conditions the air feeding spray guns in a paint booth: the 5 um element removes finer contamination that can spoil a finish, and the regulator sets a stable gun supply pressure at the booth wall.
Prepares the air for grippers, stopper cylinders and diverters on a beverage bottling line, with the regulator set once at the line drop and the manual drain emptied during scheduled changeovers.
Size and port are the first choice: 200/300/400/600 bodies with ports from 1/8 to 1 in, stepped up as your air demand grows - the 600 body here takes a 3/4 in NPT thread. Drain type matters in service: a manual drain (this unit's M code) needs periodic bowl draining, an automatic drain (A) handles condensate without attention, and the differential-pressure drain is the family default. Filter grade is 40 um standard or 5 um (this unit's W code) for finer protection. Gauge scale can be MPa, psi or bar (bar here), and the thread can be PT, G or NPT. 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. 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, not as a single rated figure, so we do not quote one number. Tell us your line pressure and air demand and we will confirm the relevant datasheet curve for this 3/4 in unit on request.
The M in the code means the bowl has a manual drain, so condensate is emptied by hand at service intervals. The same GFR family is also available with an automatic drain (code A) or the default differential-pressure drain, so ask us about those variants if you prefer unattended condensate handling.
