The AirTAC GFR60020MLJC3WT AirTAC Filter Regulator NPT3/4 Low-Pressure 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 AirTAC GFR60020MLJC3WT is a size 600 filter regulator: it removes water and particulate from compressed air and regulates downstream pressure in one body. This configuration is built with a 3/4 in NPT port, a 5 um filter element (code W), a manual drain on the aluminium alloy bowl, and the low-pressure regulator type for circuits that run below standard line pressure. A round pressure gauge scaled in bar is fitted, no mounting bracket is included, and no reverse/check valve is fitted. Maximum inlet pressure is 1.0 MPa (145 psi) and the operating temperature range is -5 to 70 C (non-freezing).
This is a genuine AirTAC part from the GFR series, which spans sizes 200 to 600 with ports from 1/8 to 1 in. Across the range you can select drain type, filter grade, gauge style and scale, thread (PT standard, G or NPT to order) and bracket options. Rated flow is published as curves rather than a single figure, so ask us to confirm the datasheet and sizing 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. 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). |
| 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. |
| (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.

Feeding spray guns and air-assisted atomisers on a finishing line, where the 5 um element keeps water and particulate out of the paint air and the low-pressure regulator holds a gentle, stable setting at the gun.
Supplying pick-and-place cylinders and vacuum-generator feed on a carton packaging line, with the manual-drain bowl emptied at shift changeover and the round bar gauge giving operators a visible setpoint.
Regulating clean, dry air to pneumatic valves and sample-handling actuators on a laboratory or pilot-plant skid, where the low-pressure type suits circuits run well below standard line pressure.
Size 600 with a 3/4 in NPT port is the largest step in the GFR range; step between 200/300/400/600 according to the flow your line needs - we confirm sizing against the published flow curves before you order. This unit carries the 5 um element (W) instead of the 40 um standard, a manual drain (the bowl is emptied by hand on a routine schedule; automatic and differential-pressure drains are available on other codes), and the low-pressure regulator type, whose exact regulation range is not published in our data - confirm with us. The fitted gauge is the external round type scaled in bar; embedded square gauges with MPa, psi or bar scales are alternatives. Thread here is NPT; PT is the standard and G is also available. No mounting bracket is included on this code (J).
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 here. Send us your line pressure and required flow and we will confirm the datasheet curve and check the sizing for your application before you order.
This code carries M, a manual drain: the aluminium alloy bowl is drained by hand on a routine schedule. If you prefer condensate discharge without attention, GFR600 codes with automatic or differential-pressure drains are available - ask us for the matching model.
