AirTAC GR600-20 Pressure Regulator (GR60020C3K)
The AirTAC AirTAC GR600-20 Pressure Regulator (GR60020C3K) 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 (GR60020C3K)
GR60020C3K is an AirTAC GR-series air pressure regulator for compressed air only. The 600 size carries a 3/4 in PT port, and this configuration adds an external round pressure gauge on a bar scale plus a reverse (check) valve that holds downstream pressure if the upstream supply dips. Outlet pressure is set anywhere in the 0.05-0.9 MPa (7-130 psi) adjustment range, with a maximum inlet pressure of 1.0 MPa (145 psi) and an operating temperature of -20 to 70 C.
This is a genuine AirTAC part from the GR series, which runs from size 200 to 600 with ports from 1/8 to 1 in and PT, G or NPT threads. GR regulators have no bowl, no filter and no lubricator, and are noted for low pressure loss; a mounting bracket can be fitted and panel mounting is possible. Flow is published as curves rather than one rated figure, so ask us to confirm sizing figures from the datasheet 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.
Model Code: AirTAC GR600-20 Pressure Regulator (GR60020C3K)
| 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. |
| 3 | Gauge scale: bar. 1 is MPa, 2 is psi, 3 is bar. |

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 (GR60020C3K) Is Used
CNC fixture clamping
Sets a steady, reduced pressure for the clamping cylinders on a CNC machining fixture, so workholding force stays consistent part after part.
Packaging line stops and diverters
Feeds the stop and divert cylinders on a packaging conveyor at the pressure the mechanism was designed for, independent of shop-air swings.
Bottling line gate actuators
Regulates supply air to gate and filler actuators on a bottling line, with the check valve holding the downstream setting if upstream supply drops.
Is the AirTAC GR600-20 Pressure Regulator (GR60020C3K) the Right Regulator?
Choose the GR size by the air your circuit consumes: 200 through 600 step up both the port and the flow capacity, and this 600 unit has a 3/4 in PT port. PT is the standard thread, with G (BSPP) and NPT available as catalogue options to order. Gauge choices are the embedded square gauge or an external round gauge on MPa, psi or bar scales - this code carries the round gauge with a bar scale. The K suffix adds the reverse/check valve, and the standard (non-L) type covers the full 0.05-0.9 MPa (7-130 psi) setting range.
Flow is published as curves, not a single rated figure, so send us your line pressure and air demand and we will confirm sizing against the datasheet before you order.
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 (GR60020C3K) FAQ
AirTAC publishes GR flow as performance curves rather than one rated figure, so no single flow number is quoted here. Tell us your inlet pressure and the air demand of the circuit, and we will confirm the sizing from the datasheet on request before you order.
C specifies the external round pressure gauge, 3 sets its scale to bar, and K means a reverse (check) valve is fitted so downstream pressure is held if the upstream supply fails. Codes without K omit the valve, and square gauges with MPa, psi or bar scales are the other catalogue choices.
