GPR Series Precision Regulator
High Responsiveness | Superior Flow Characteristics
Product Features
- High Precision: Offers a wide pressure adjustment range with exceptional responsiveness, sensitivity (within 0.2% F.S.), and repeatability (within ±0.5% F.S.).
- Excellent Characteristics: Delivers highly stable pressure and superior flow characteristics, making it ideal for delicate tension control and precision balancing applications.
- Flexible Installation: Extremely easy to install. It can be mounted independently using the included bracket, or seamlessly integrated and combined with our modular GAF series air filters.
- Multiple Configurations: Designed to accommodate various application needs; in addition to standard panel installation, specialized medium and low-pressure types are available.
Critical Application Note: Precision regulators have highly sensitive internal mechanisms. If water droplets, oil, or dust are present in the upstream air supply, it may cause immediate malfunction. A 5μm filter (like our GAF series) MUST be installed upstream. Additionally, a mist separator (our GFF series) is highly recommended for oil degreasing.
