The AirTAC GFR60020MLJC1T AirTAC Filter Regulator NPT3/4 Low-Pressure 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 GFR60020MLJC1T is a GFR600 filter regulator: water and particulate filtration plus pressure regulation combined in one body. Compressed air passes a 40 um filter element and is then regulated downstream. This configuration has a 3/4 in NPT thread, a manual-drain bowl in aluminium alloy, the low-pressure regulator type, and a round pressure gauge with MPa scale 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. The GFR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, and options include automatic, manual or differential-pressure drains, a 5 um element (code W), square or round gauges with MPa, psi or bar scales, and G or NPT threads in place of the PT standard. Flow is published as curves rather than a single rating, 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. 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. |
| 1 | Gauge scale: MPa. 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.

Feeding filtered, regulated air to the gripper and capper actuators on a bottling line, where the low-pressure regulator type holds a gentler setting than standard plant pressure and the manual drain is bled at shift checks.
Supplying the diverter cylinders on a distribution conveyor, with the 40 um element keeping pipe scale and rust out of the downstream valve stack and the round MPa gauge giving operators a clear local reading.
Conditioning the bench air supply in a test laboratory, where the low-pressure regulation, aluminium bowl and MPa gauge suit a fixed, supervised installation with a 3/4 in main feed.
Size 600 is the largest GFR frame, with a 3/4 in port suited to higher air demand; step down to 300 or 400 if your circuit draws less. The manual drain here needs periodic bleeding by hand, so choose automatic or differential-pressure draining if the unit sits where nobody walks. The low-pressure regulator type suits circuits running below standard plant pressure; we confirm its exact adjustment range from the datasheet on request. The 40 um element is standard and the W code orders 5 um. The gauge here is round with an MPa scale; psi or bar scales and the embedded square gauge are alternatives. G (BSPP) or NPT threads can be ordered instead of PT, and a mounting bracket is optional. Because flow is published as curves, not a single rating, 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 GFR flow as curves, not a single rated figure, so we do not quote a number here. Send us your line pressure and air demand and we will confirm the datasheet curve and sizing for your application on request.
The M in the code sets a manual drain: condensate collects in the aluminium bowl and is bled by hand, which suits attended installations on a regular check round. If the unit sits in an inaccessible spot, the same GFR600 body is available with automatic or differential-pressure draining - ask us for that variant.
