The AirTAC GR60020JC3T 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 AirTAC GR60020JC3T is a GR-series air pressure regulator in size 600 with 3/4 in NPT ports. It reduces and holds downstream pressure across an adjustment range of 0.05-0.9 MPa (7-130 psi), with a maximum inlet pressure of 1.0 MPa (145 psi). This configuration is fitted with a round pressure gauge reading in bar, and the standard type covers normal line duty. As a pure regulator it contains no filter and no bowl, so it belongs where the air is already filtered and only pressure control is needed.
This is a genuine AirTAC part. The GR family spans sizes 200, 300, 400 and 600 with ports from 1/8 to 1 in, in PT (standard), G and NPT threads, with embedded square or external round gauges in MPa, psi or bar scales, an optional low-pressure type limited to 0.4 MPa, an optional reverse/check valve, and bracket or panel mounting. Operating temperature is -20 to 70 C, wider 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.

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.

On a stamping or assembly press line, the GR60020JC3T sits after the filter stage and holds a steady working pressure to the press cylinders so stroke force stays repeatable through the shift.
As the main regulator on a CNC machine or automated cell air manifold, it lets a technician set and read the supply pressure in bar on the round gauge, keeping valves and actuators on one stable setting.
On a bottling or packaging conveyor with air-driven diverters and clamps, this 3/4 in regulator keeps the supply pressure constant so gate timing and clamp grip do not drift as demand changes.
Size 600 with 3/4 in NPT ports suits lines where larger piping and heavier air demand are expected; step down to GR200, GR300 or GR400 for smaller ports, matching the port step to the flow your circuit needs. The real decodable choices on this family are: gauge style and scale (this unit carries a round gauge in bar; embedded square gauges in MPa, psi or bar are the alternatives), thread (PT is the standard, G and NPT are order options - this unit is NPT), the low-pressure L type limited to 0.4 MPa, a K-coded reverse/check valve, and the bracket decision (this unit is supplied without a bracket, and GR is also panel-mountable). Flow is published as curves, not a single rating, 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 regulator flow as curves rather than a single rated figure, so quoting one number would not be honest. Tell us your line pressure, set pressure and the equipment downstream, and we will confirm the flow from the GR600 datasheet on request before you order.
The C in the code selects the external round gauge, and the 3 sets its scale to bar. The embedded square gauge is the standard fitting, with MPa, psi or bar scales available, so a square gauge in another scale can be chosen instead - just set the gauge digits when ordering.
