The AirTAC GFR60020MC3WT 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 GFR60020MC3WT is an AirTAC GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in a single body. This configuration filters compressed air down to 5 um (the fine W grade, against the standard 40 um element) while regulating downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range. It is a size 600 unit with a 3/4 in NPT port, a manual drain on the bowl, and a round pressure gauge reading in bar. The bowl on this largest frame is aluminium alloy, maximum inlet pressure is 1.0 MPa (145 psi), and the working temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part. The GFR series is published in sizes 200, 300, 400 and 600 with ports from 1/8 to 1 inch, a choice of differential-pressure, automatic or manual drain, 40 um or 5 um filtration, embedded square or external round gauges with MPa, psi or bar scales, and PT, G or NPT threads. Flow is published as curves rather than a single rating, so ask us to confirm the figures from the datasheet 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). |
| C | Gauge shape: Round. 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.

Feeding spray booths and paint guns from the shop air main, where water and fine particles must be stripped out and the gun supply pressure set and held steady for a consistent finish.
Conditioning the air feeding clamps, tool-change cylinders and air blow-off on a machining centre, with the regulator set to the pressure the machine builder specifies.
Supplying clean, regulated air to the cylinders and vacuum generators on a carton former or case sealer, keeping actuation pressure stable through the whole shift.
Size and port set the capacity: the 600 frame with its 3/4 in NPT port is the largest step in the GFR range, so match it against the flow your line needs - flow is published as curves, not a single rating, so ask us to confirm sizing against the datasheet before ordering. This code pairs a manual drain (you drain the bowl by hand, which is simple and positive) with the 5 um W-grade element for finer filtration than the standard 40 um. The gauge fitted is the external round type reading in bar; the embedded square gauge with MPa, psi or bar scale is the catalogue alternative. PT is the standard thread and G (BSPP) and NPT are order options - this code specifies NPT. Mounting bracket included.
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 series as curves rather than a single rated figure, so we do not quote a number that could mislead your sizing. Tell us your line pressure, set pressure and demand, and we will confirm the flow figures from the datasheet for this exact unit before you order.
In the code GFR60020MC3WT, the M sets a manual drain - the bowl is drained by hand rather than automatically - and the W sets the fine 5 um filter grade instead of the standard 40 um element. If you would rather not rely on someone draining the bowl, the same unit is available with automatic or differential-pressure drain; ask us for the alternative code.
