The AirTAC GR60020NT AirTAC Air Pressure Regulator, NPT 3/4 in is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 MPa (7 - 130 psi) with PT3/4" ports, ordered without a 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 GR60020NT is an AirTAC GR-series air pressure regulator for compressed air, built to hold a steady downstream pressure from a variable supply. This is the 600 size with a 3/4 in NPT thread, in the standard type with a 0.05-0.9 MPa (7-130 psi) adjustment range and a maximum inlet pressure of 1.0 MPa (145 psi). No gauge is fitted in this configuration, and the unit operates from -20 to 70 C, the widest temperature window in the G family. A mounting bracket is included, and the body is also panel-mountable.
This is a genuine AirTAC part. The GR600 is the largest size in the GR regulator line, with 1/2 in to 1 in ports available in that size step, and options across the series include a fitted pressure gauge in square (embedded) or round (external) style with MPa, psi or bar scale, a low-pressure type limited to 0.4 MPa, and a reverse/check valve. 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. 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.

| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |

| N | No pressure gauge (N). |
| (blank) | Gauge shape: Factory standard. C is round, F is square. |
| (blank) | Gauge scale: Factory standard. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |

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 stable downstream pressure feeding a bank of directional control valves on a machine's air manifold, so cylinder and actuator speeds stay repeatable as plant supply pressure wanders.
Regulate the air to a pneumatic press or clamping fixture on a fabrication cell, holding the clamping circuit at the pressure the tooling was set up for, independent of the shop main.
Feed the sealing and sorting actuators on a packaging line at a controlled pressure, keeping the machine's setpoints consistent shift after shift on a 3/4 in air drop.
Start with the port and size step: the 600 size with a 3/4 in NPT thread suits lines plumbed at 3/4 in, and the larger the size step, the larger the port and the flow path. Set the downstream pressure anywhere in the 0.05-0.9 MPa (7-130 psi) range; if your process runs below that, the GR low-pressure type (L) covers settings up to 0.4 MPa. This unit ships with no gauge fitted, so add a gauge code if you want local pressure indication, choosing square (embedded) or round (external) and an MPa, psi or bar scale. Thread is NPT here; PT is the AirTAC standard and G (BSPP) is also a catalogue option to order. A mounting bracket is included, and GR also panels directly. Because flow is published as curves and not a single rating, ask us to confirm sizing against your air demand 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 regulator flow as curves, not as a single rated number, so we do not quote a Cv, l/min or SCFM figure. Send us your line pressure, set pressure and expected air consumption, and we will confirm the flow and datasheet figures for the GR600 at 3/4 in NPT before you order.
Yes. The N in the code means no gauge is fitted on this unit; GR regulators can be ordered with an embedded square gauge or an external round gauge, in MPa, psi or bar scale. On thread, this unit is NPT 3/4 in; PT is the AirTAC standard and G (BSPP) is also available as a catalogue option to order.
