The AirTAC GFR60020MJC3TK AirTAC 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 GFR60020MJC3TK is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration has a 3/4 in NPT port, a manual drain on the aluminium alloy bowl, a 40 um filter element, a fitted reverse/check valve, and an external round pressure gauge with a bar scale. Maximum inlet pressure is 1.0 MPa (145 psi), the operating temperature range is -5 to 70 C (non-freezing), and the regulator adjusts from 0.05 to 0.9 MPa (7-130 psi).
This is a genuine AirTAC part. The GFR series is available in sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, and with choices of drain type, 40 um or 5 um filtration, gauge style and scale, G, NPT or PT thread, and bracket. Flow is published as curves rather than a single rated figure, so ask us to confirm the datasheet figures 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. 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. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 3 | Gauge scale: bar. 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. |

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.

Point-of-use conditioning for a spray booth: the 40 um element strips water and pipe scale before the regulator holds a steady set pressure to the spray guns, and the manual drain lets the operator bleed accumulated condensate at shift end.
Feeding cylinders and stopper gates on a bottling conveyor: the regulator keeps actuator pressure consistent along the 3/4 in main, the reverse/check valve holds downstream pressure if the supply drops, and the bar-scale gauge gives operators a visible set point.
A compact conditioning and regulation stage in a machine tool's pneumatic cabinet: filtered, regulated air to the tool changer and clamping circuits, with the round gauge mounted for at-a-glance pressure checks during setup.
Size 600 with a 3/4 in port is the largest step in the GFR range; step between 200, 300, 400 and 600 against the flow your line needs, and ask us to confirm sizing from the flow curves. Drain choice matters: a manual drain needs an operator to bleed the bowl, while automatic and differential-pressure drains discharge condensate without attention. The 40 um element is standard here; specify 5 um (code W) when downstream equipment needs finer filtration. Thread is NPT on this unit; G (BSPP) and PT are order options. This unit is configured without a mounting bracket and carries a round gauge with a bar scale; embedded square gauges with MPa, psi or bar scales are also available.
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, not as a single rated number, so we do not quote a rated flow, Cv or SCFM figure. Tell us your application and we will confirm the relevant flow figures from the datasheet before you order.
The M in the code sets a manual drain: condensate collects in the aluminium alloy bowl until an operator opens the drain. Choose manual where the unit is checked daily or runs intermittently; choose automatic or differential-pressure drain where the line runs unattended and condensate must be discharged without attention.
