The AirTAC GR60020LJF2T AirTAC Air Pressure Regulator NPT3/4 is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.4 MPa (7 - 58 psi) with PT3/4" ports, and ships with a pressure gauge. A regulator does not filter the air — put a GF filter upstream, or use a GFR filter regulator, when water and particulate must also be removed.
The GR60020LJF2T is an AirTAC GR-series air pressure regulator in size 600, the largest step in the range, with 3/4 in NPT ports. This is the low-pressure type, so it regulates outlet pressure up to 0.4 MPa, and it is built for compressed air only. It handles a maximum inlet pressure of 1.0 MPa (145 psi) and operates from -20 to 70 C, a wider temperature window than the rest of the G family. A square pressure gauge scaled in psi is fitted so the set pressure can be read directly at the unit, and the J code means no mounting bracket is supplied; the GR body is also panel-mountable.
This is a genuine AirTAC part. The GR line spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, in standard or low-pressure types, with or without a gauge, bracket or reverse/check valve, and in PT, G or NPT thread. Flow is published as curves rather than a single rated figure, so ask us and we will confirm the datasheet figures for your application on request.

Specifications follow the official AirTAC G-series air-preparation data. Note the GR temperature range is -20 to +70 °C, wider than the other G-series units. A regulator has no bowl and no filter element, so there is no filtering grade. 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". |
| L | Low-pressure type — 0.05 - 0.4 MPa (7 - 58 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| F | Gauge shape: Square. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| 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, type, bracket, gauge, gauge shape, scale, thread, reflux — a blank position takes the default. Example: GR300-08LNK is a 300 body, PT1/4", low-pressure type, no gauge, with 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 rather than from a single rated figure.

On a carton-sealing or wrapping line where actuators and clamps are specified for a low supply pressure, this low-pressure GR600 regulator holds the set point at the 3/4 in drop from the main header, with the psi gauge visible for operator checks.
Spray guns and atomising air on a coating line call for a steady, reduced pressure rather than full header pressure. This size 600 regulator in NPT3/4 sits at the booth drop and lets the operator set and read the pressure in psi directly.
Where a workshop ring main runs at full compressor pressure, this GR600 low-pressure regulator drops the supply for a section of the plant that only needs a reduced, stable pressure, with the square gauge giving a local psi readout.
Start with the port and size step: size 600 with 3/4 in NPT ports is the right choice when your line is plumbed at 3/4 in and your flow demand sits at the top of the GR range. Because flow is published as curves, not a single rating, ask us to confirm the sizing against your application before ordering. This unit is the L low-pressure type, so choose it when your set pressure stays within 0.4 MPa; for higher set pressures pick a standard GR600 instead. The fitted square gauge reads in psi; MPa or bar scales and an external round gauge are catalogue options. Thread is NPT here, with PT as the standard and G (BSPP) also available to order. The J code means no bracket is included, so plan for panel mounting or add a bracket variant if you need one.
Quick checklist
Without a reflux valve, air cannot flow back through the regulator — order the K option if reverse flow is required. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure for this unit. Tell us your line pressure, set pressure and expected air demand, and we will confirm the datasheet curve data for the GR600 size on request before you order.
The L in the model code marks the low-pressure regulator type, which regulates outlet pressure up to 0.4 MPa instead of the standard GR range. The F2 code means a square gauge scaled in psi is fitted so the set pressure can be read at the unit; MPa or bar scales and an external round gauge are available as catalogue options.
