The AirTAC GR60020JC2TK AirTAC Air Pressure Regulator, NPT3/4 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 GR60020JC2TK is an AirTAC GR600 air pressure regulator for compressed air, built for the 600 size frame with a 3/4 in NPT thread. It is a regulation-only device: it holds a steady downstream pressure setting from the incoming shop-air supply and carries no filter, no bowl and no lubricator. This configuration is fitted with an external round pressure gauge reading in psi, a reverse/check valve on the outlet side, and no mounting bracket - the GR600 body is also panel-mountable where a bracket is not wanted. Maximum working (inlet) pressure is 1.0 MPa (145 psi), the standard adjustment range is 0.05-0.9 MPa (7-130 psi), and the operating temperature window is -20 to 70 C, wider than the rest of the G-series families.
This is a genuine AirTAC part from the GR family, which spans the 200, 300, 400 and 600 sizes with port sizes from 1/8 in up to 1 in, PT as the standard thread and G (BSPP) or NPT as order options, plus gauge, bracket, low-pressure and check-valve variants. Because flow for this series is published as curves rather than a single rated figure, ask us and we will confirm the datasheet and sizing figures for 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.

| 20 | Port size PT3/4". This body offers 20 = PT3/4", 25 = PT1". |
| (blank) | Standard type — 0.05 - 0.9 MPa (7 - 130 psi). Blank is standard, L is the low-pressure type. |
| J | Supplied without bracket. |

| C | Gauge shape: Round. C is round, F is square. |
| 2 | Gauge scale: psi. 1 is MPa, 2 is psi, 3 is bar. |
| T | NPT thread. PT is the default; G is BSPP and T is NPT. |
| K | Reverse-flow (reflux) valve fitted. |
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.

Installed at a 3/4 in branch take-off from a factory compressed-air ring main, it sets a stable working pressure for the machines fed from that drop, while the check valve keeps the setting if the main is shut off.
On a cartoning or wrapping line, the regulator feeds the machine's cylinder and actuator circuit at the pressure the machine builder specifies, with the psi gauge giving operators a local reading at the setpoint.
On a CNC fixture or jig clamping circuit, it holds the clamp pressure the process calls for, and the reverse/check valve prevents the clamps venting if upstream air to the cell is interrupted.
Choose the size and port step against the air demand of the circuit downstream - the GR600 is the largest frame in the GR range, here with a 3/4 in NPT port, and the smaller 200/300/400 sizes step down in port and flow capacity. Decide the gauge you want: this unit ships with the external round gauge in psi; square embedded gauges and MPa or bar scales are the other catalogue choices. Set the thread to match your piping - PT is the AirTAC standard, while G (BSPP) and NPT are ordered options, and this code carries the NPT variant. Other real choices are the bracket (this code omits it; the body is panel-mountable) and the reverse/check valve, which is fitted on this unit to hold the downstream setting when upstream supply is lost. Flow for the GR series is published as curves, not a single rating, so ask us to confirm sizing against your application before ordering.
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-series flow as performance curves rather than a single rated figure, so we do not quote a number. Send us your line pressure, downstream demand and allowable pressure drop, and we will confirm the sizing from the datasheet on request.
In GR60020JC2TK, the C2 means an external round gauge is fitted with a psi scale (MPa and bar scales, and the embedded square gauge, are the other catalogue choices), and the K means a reverse/check valve is fitted on the outlet. The J means no mounting bracket is included; the GR600 body is also panel-mountable.
