AirTAC GR600-20 Pressure Regulator (GR60020C1K)
The AirTAC AirTAC GR600-20 Pressure Regulator (GR60020C1K) 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 (GR60020C1K)
The GR60020C1K is a genuine AirTAC G-series air pressure regulator in the largest size 600 body with a 3/4 in PT port, built in the K configuration with a reverse/check valve fitted. It reduces compressed-air supply pressure to a stable working setting across the 0.05-0.9 MPa range, tolerates up to 1.0 MPa (145 psi) inlet, and carries an external round gauge scaled in MPa. The fitted check valve makes it the choice where the circuit calls for a regulator with reverse-flow protection as part of the code.
Across the GR series you can move between sizes 200, 300, 400 and 600, and between PT, G (BSPP) and NPT threads, round or square gauges, and MPa, psi or bar scales. This unit is regulation only - there is no filter element or drain bowl on any GR. Flow is published as curves rather than a single rating, so we confirm the AirTAC datasheet 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.
Model Code: AirTAC GR600-20 Pressure Regulator (GR60020C1K)
| 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. |
| (blank) | Fixing bracket included. |
| (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.
Size Class

- GR400PT3/8" - PT1/2"
- GR600PT3/4" - PT1"
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 (GR60020C1K) Is Used
Robot cell gripper air circuits
Regulate supply air to gripper and tool-changer circuits on robotic welding and handling cells where the specification calls for a check valve in the line.
Press-shop clamp circuits
Set working pressure for pneumatic clamp and kicker cylinders on stamping-press peripheral equipment, with reverse-flow protection built into the regulator.
Test rig manifold supply
Feed regulated air to leak-test and functional-test manifolds on a production test bench, keeping the set pressure readable and the circuit protected per the K code.
Is the AirTAC GR600-20 Pressure Regulator (GR60020C1K) the Right Regulator?
Use the K suffix when your schematic calls for a reverse/check valve in the regulator; without it, order the plain GR60020C1. Size 600 with the 3/4 in port is the top GR step for main drops and high-draw headers. The C1 round MPa gauge suits teams working in MPa; the C3 bar-scale variant is otherwise identical. Thread is PT as standard, with G and NPT as orderable catalogue options, and brackets are optional.
As with every GR, flow is not published as a single rated number - only as curves. Send us your duty conditions and we will confirm GR60020C1K sizing from the datasheet on request.
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 (GR60020C1K) FAQ
No single rated flow exists for this unit - AirTAC publishes GR600 performance as pressure-drop curves, which is why we do not quote a number. Tell us your application conditions and we will confirm the relevant flow data from the AirTAC datasheet on request.
K is the code for a reverse/check valve fitted to the regulator. If your circuit does not require one, the equivalent unit without the valve is the GR60020C1 - same 3/4 in PT port, size 600 body, 0.05-0.9 MPa setting range and round MPa gauge.
