The AirTAC GR60020LF3T AirTAC Low-Pressure Regulator 3/4in NPT 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 GR60020LF3T is an AirTAC GR-series air pressure regulator in the size 600 frame with a 3/4 in NPT port. The L in the code marks the low-pressure type, so it regulates outlet pressure up to 0.4 MPa, and the F3 specifies the embedded square gauge scaled in bar. The mounting bracket is included, and the GR body can also be panel-mounted. As a regulator it does one job only: holding a steady downstream pressure from your compressed-air supply. There is no filter, no bowl and no lubricator in this unit.
This is a genuine AirTAC part. The GR family spans sizes 200 to 600 with port sizes from 1/8 to 1 in, standard or low-pressure regulation, gauge or no gauge, and PT, G or NPT thread options. Rated inlet pressure is 1.0 MPa (145 psi), and the GR works from -20 to 70 C, a wider window than the rest of the G family. 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. 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. |

| F | Gauge shape: Square. C is round, F is square. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

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.

Set a gentle holding pressure for pneumatic clamps on a woodworking or fixture line, where the cylinders must never see more than 0.4 MPa.
Regulate low-pressure atomizing air to spray guns in a paint booth, keeping the mist pressure steady through a full shift.
Feed looms or textile finishing machines that run on low-pressure air, with the bar-scale gauge letting operators check settings at a glance.
Choose the size by the flow your line needs: 600 is the largest GR frame and carries the 3/4 in port on this unit, with 200/300/400 steps below it. This code specifies the low-pressure type, so it suits circuits that never need more than 0.4 MPa downstream; the standard GR covers up to 0.9 MPa. The square gauge here is scaled in bar, with MPa and psi scales and an external round gauge as catalogue options. The thread is NPT on this unit, with PT (the standard) and G available as options, and the mounting bracket is included. Flow is published as curves, not a single rated figure, so send us your application and we will confirm sizing against the datasheet before you order.
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 GR flow as curves rather than a single rated figure, so we do not quote a number here. Tell us your line's flow and pressure demand and we will confirm the right size from the datasheet on request.
L marks the low-pressure type: this regulator adjusts outlet pressure up to 0.4 MPa instead of the standard GR range. F3 means the embedded square gauge is scaled in bar, and the trailing T specifies the NPT thread; the mounting bracket is included as standard.
