The AirTAC GR60020NTK AirTAC Air Pressure Regulator 3/4in NPT is a genuine G-series air pressure regulator. It holds a stable downstream pressure over the range 0.05 - 0.9 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 GR60020NTK is an AirTAC GR-series air pressure regulator, built for regulation only: it holds a steady downstream pressure from your compressed-air supply, with no filtration and no lubrication in this unit. This 600-size configuration is specified with a 3/4 in NPT port, the standard regulator type with an adjustment range of 0.05-0.9 MPa (7-130 psi), and a reverse/check valve fitted so downstream pressure is held if the upstream supply drops. No gauge is fitted in this code, and a mounting bracket is included; GR bodies are also panel-mountable.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 in to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, an optional low-pressure type (L, up to 0.4 MPa), and gauge choices including no gauge (N), an embedded square gauge or an external round gauge in MPa, psi or bar scales. We confirm flow and datasheet figures on request, since flow is published as curves rather than a single rating.

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. |

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 on a 3/4 in header drop feeding a bay of air cylinders, it holds a fixed working pressure for the actuators regardless of swings in the compressor supply, with the check valve holding the circuit if the header dips.
On a machine tool or fixture line, it regulates the supply to clamping cylinders so clamp force stays consistent from cycle to cycle, with the bracket mounting it at the machine's air preparation point.
Feeding the valve manifold of a packaging or conveyor line, it steps the 3/4 in main supply down to the stable pressure the diverters, stoppers and grippers were designed around, with no gauge cluttering the panel where a central gauge is read instead.
Start with the size and port: 200, 300, 400 and 600 step up in port size and flow capacity, so match the 3/4 in NPT porting here against your line size and required flow. Decide the gauge: this code (N) ships with no gauge, but you can order a version with an embedded square gauge or an external round gauge in MPa, psi or bar scales. Choose the thread: PT is the standard, with G (BSPP) and NPT available as order options - this unit is the NPT version. If your set pressure never exceeds 0.4 MPa, the low-pressure L type is available; the reverse/check valve (K) is worth specifying where a cylinder or process must hold pressure through a supply dropout. A mounting bracket is included, and GR also panels.
One honest note before you order: AirTAC publishes regulator flow as curves, not as a single rated number, so we do not quote a flow figure here. Send us your line size and demand and we will confirm sizing against the datasheet curves before you commit.
Quick checklist
The reflux valve lets air flow back through the regulator, which is useful when downstream volume must vent quickly. A regulator does not remove water or particulate; that is the filter's job.
AirTAC publishes regulator flow as characteristic curves rather than a single rated figure, so we do not state a flow number here. Tell us your upstream pressure, set pressure and air demand, and we will confirm the sizing against the datasheet curves on request before you order.
Yes. The N in GR60020NTK means no gauge is fitted, but GR versions are available with an embedded square gauge or an external round gauge in MPa, psi or bar scales. The K means a reverse/check valve is fitted, so downstream pressure is held if the upstream supply is lost. The unit also carries a mounting bracket and can be panel-mounted.
