AirTAC GR600-20 Pressure Regulator (GR60020JC1K)
The AirTAC AirTAC GR600-20 Pressure Regulator (GR60020JC1K) 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.

About the AirTAC GR600-20 Pressure Regulator (GR60020JC1K)
The GR60020JC1K is an AirTAC G-series air pressure regulator for compressed air only. It regulates downstream pressure across a 0.05-0.9 MPa (7-130 psi) adjustment range with a maximum inlet pressure of 1.0 MPa (145 psi). The 600 size carries a 3/4in PT port, the K suffix adds a reverse (check) valve against outlet backflow, the C1 suffix selects an external round gauge with MPa scale, and the J means no mounting bracket. It filters nothing and adds no oil.
This is a genuine AirTAC part in the 600 size, the largest step of the G series (200/300/400/600). GR regulators offer low pressure loss, embedded square or external round gauges with MPa/psi/bar scales, panel mounting as well as optional brackets, and G (BSPP) or NPT thread options at order. Operating temperature is -20 to 70 C. Flow is published as curves, not a single rating, so we confirm datasheet figures 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.
Model Code: AirTAC GR600-20 Pressure Regulator (GR60020JC1K)
| GR600 | G-series pressure regulator, 600 body — sets the port range. |
|---|---|
| 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. |
| (blank) | Pressure gauge fitted (blank). |
| C | Gauge shape: Round. C is round, F is square. |
| 1 | Gauge scale: MPa. 1 is MPa, 2 is psi, 3 is bar. |
| (blank) | PT 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.

Where the AirTAC GR600-20 Pressure Regulator (GR60020JC1K) Is Used
Hydraulic power unit accumulator charging
Regulating the pilot or air-over-oil supply to a hydraulic power unit with an air-charged accumulator, where the check valve stops stored pressure from feeding back when supply is lost.
Bottling line take-off regulation
Setting pressure on a 3/4in take-off feeding the filler, capper and rejection stations of a bottling line, with backflow protection for isolated machine sections during changeover.
Trailer loading dock actuation supply
Controlling supply to dock leveller and restraint pneumatics on a 3/4in branch, where the reverse valve holds set circuit pressure when the upstream supply is isolated.
Is the AirTAC GR600-20 Pressure Regulator (GR60020JC1K) the Right Regulator?
Choose the K variant when the outlet side can ever pressurise backward - for example on branched lines or machines with stored-energy circuits - and the plain code where it cannot. The 600 size with 3/4in PT port serves larger headers than the 200/300/400 units. This code pairs the external round MPa gauge (C1) with no bracket (J); pick the same body with a psi or bar scale, with the square gauge, or without a gauge (N) as needed.
PT is the standard thread and G (BSPP) or NPT are catalogue alternatives to specify at order. Because flow is shown as curves rather than a rated figure, ask us to confirm sizing against the datasheet for your demand before you commit.
Quick checklist
- ✓ Body size for your peak flow (PT3/4" here)
- ✓ Standard 0.9 MPa or low-pressure 0.4 MPa
- ✓ Gauge fitted, or order N without
- ✓ Gauge shape C round / F square
- ✓ Scale MPa (1), psi (2) or bar (3)
- ✓ Reflux valve needed, order K
Installation & Maintenance Notes
- check Install downstream of the filter, following the airflow arrow.
- check Keep inlet pressure at or below 1.0 MPa (145 psi).
- check Set pressure while air is flowing, then lock the knob.
- check Adjust within 0.05 - 0.9 MPa (7 - 130 psi) only.
- check Operating range -20 to +70 °C.
- check Panel-mount or use the fixing bracket; do not hang it on tubing.
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 GR600-20 Pressure Regulator (GR60020JC1K) FAQ
Yes - on request. AirTAC publishes GR flow as curves, not as one rated figure, so we do not state a number on the page. Give us your inlet pressure, set pressure and expected demand, and we will confirm the applicable flow figures from the datasheet.
The only difference is the K: this code has a reverse (check) valve fitted so downstream air cannot flow back through the regulator. Function, 3/4in PT port, adjustment range, round MPa gauge and no-bracket configuration are otherwise the same.
