The AirTAC GR60020C3T 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, 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 GR60020C3T is an AirTAC GR-series air pressure regulator in the largest size of the range, sized 600 with a 3/4 in NPT port. It does one job only: reducing and holding downstream air pressure. This standard-type unit adjusts across 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi), and it operates from -20 to 70 C, a wider temperature window than the rest of the G family. A round pressure gauge with a bar scale is fitted for direct setpoint reading, and the mounting bracket is included; the GR series 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 up to 1 in, and options include PT, G or NPT threads, a low-pressure type, a reverse/check valve, and gauge scale choices. Flow figures for the GR600 are published as curves rather than a single rating, so ask us to confirm the datasheet 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.

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.

Settling a stable, reduced pressure on a 3/4 in branch line feeding a production hall section, so downstream machines see a consistent supply regardless of header swings.
Holding the set clamping pressure on air-powered presses, clamps and workholding fixtures where the operator sets a bar-scale gauge once and the circuit holds it.
Trimming line pressure ahead of valve manifolds and actuators in a robotic assembly cell, protecting components that are specified below full header pressure.
Start with the port: the GR60020C3T carries a 3/4 in NPT thread, so match it to your supply line and the pipe size your flow demand implies - the 600 size is the largest step in the GR range. Set the working pressure inside the 0.05-0.9 MPa (7-130 psi) adjustment range and check your compressor output stays under the 1.0 MPa (145 psi) maximum inlet. Choose the gauge scale you read in: this unit ships with a round bar gauge, and MPa or psi scales are available. Thread is decodable at order time - PT is the catalogue standard, with G (BSPP) and NPT as options, so pick the one your piping uses. A low-pressure type (up to 0.4 MPa) and a reverse/check valve can be specified if the application needs them. Sizing against real air demand is the one step we recommend not guessing: flow is published as curves, not a single rated figure, so send us your application details and we will confirm the datasheet match 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-series flow as performance curves rather than a single rated figure, so we do not quote a flow number for this regulator. Tell us your line size and air demand and we will confirm the datasheet and curve fit for your application on request before you order.
Yes. Thread is a decodable order option on the GR series: PT is the catalogue standard, and G (BSPP) or NPT are specified by the trailing code. The GR60020C3T you are viewing is the NPT version with a 3/4 in port; the same 600-size regulator can be ordered in the other threads as a catalogue option.
