The AirTAC GR60020C2K AirTAC Air Pressure Regulator PT3/4 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 GR60020C2K is an AirTAC GR600 air pressure regulator in the largest frame of the GR range, fitted with 3/4 in PT ports. It performs one job only: reducing and holding a stable downstream pressure from a compressed-air supply, adjustable across 0.05-0.9 MPa (7-130 psi) with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration carries the external round gauge with a psi scale, a built-in reverse (check) valve, and the mounting bracket, and it is rated for ambient temperatures of -20 to 70 C - a wider window than the rest of the G-series, which suits colder plant air.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with port sizes from 1/8 to 1 in, optional G (BSPP) or NPT threads in place of the PT standard, gauge scale choices of MPa, psi or bar, a low-pressure type, and a version without the check valve. Flow figures for the GR600 are published as curves rather than a single rating, so ask us and we will confirm the datasheet figures against 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.

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.

Dropping a 3/4 in compressed-air distribution header down to a stable working pressure for a production hall, with the psi gauge giving operators a direct local reading and the check valve holding the circuit if the upstream supply dips.
Regulating the feed to carton-forming and wrapping machinery on a packaging line, where cylinders and actuators need a steady set pressure held constant through the shift regardless of header fluctuation.
Supplying the air cylinder circuit that raises and lowers stoppers and gates along a conveyor line, with the regulator set to the pressure the gate cylinders were designed for and the check valve keeping the setting during supply loss.
Size and port are the first decision: the 600 frame with its 3/4 in PT ports is the step to take when line volume points to the top of the GR range - match it to your supply piping rather than guessing from a flow number, since GR flow is published as curves only. Next set the gauge: this unit is ordered with the external round gauge on a psi scale; MPa or bar scales are available if your plant reads metric. The trailing K in the code means a reverse (check) valve is fitted, holding downstream pressure if the supply side drops; order the plain code if you do not want it. Thread is PT as standard, with G (BSPP) and NPT as orderable options, and the bracket is included, with panel mounting also possible on GR. Because sizing against real demand matters, send us your application details and we will confirm the flow curves from the datasheet before you order.
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 GR regulator flow as characteristic curves rather than a single rated figure, so there is no one number we can honestly quote. Tell us your inlet pressure, set pressure and expected air demand, and we will confirm the flow capability from the GR600 datasheet curves for your application on request.
K means a reverse (check) valve is fitted, so downstream pressure is held if the supply side loses pressure. The same regulator without the K code is supplied without the check valve. The rest of the code decodes as: GR600 size with 3/4 in PT ports, round gauge on a psi scale (C2), and the mounting bracket included.
