ROSS HOZE-FUZE® 1969A3001: Enhanced Safety for Pneumatic Systems
The ROSS HOZE-FUZE® 1969A3001 is a safety device engineered to mitigate the risks associated with hose or plastic tubing failures in pneumatic systems. Designed to automatically reduce airflow upon detecting a hose rupture, it effectively minimizes the hazardous whip effect that can occur during such incidents.
Key Features
- Automatic Airflow Reduction: Activates upon hose failure to limit air discharge and prevent hose whip.
- High Pressure Capacity: Operates efficiently up to a maximum pressure of 260 PSI (17.9 Bar).
- Durable Construction: Composed of an aluminum body and Hostalen piston for longevity and reliability.
- Temperature Resilience: Functions within a temperature range of -4°F to 275°F (-20°C to 135°C).
- Easy Reset Mechanism: Simply shut off the air supply to reset the device after activation.
Specifications
- Model Number: 1969A3001
- Thread/Porting: 3/8″ NPT Male-Female
- Overall Length: 2.8 inches (71 mm)
- Hex Flat Dimension: 1.1 inches (27 mm)
- Weight: 1.4 lbs (0.62 kg)
Operational Details
Upon hose failure, the HOZE-FUZE® restricts airflow to minimize hose whip. A minimal pilot flow continues until the device is reset by shutting off the air supply. It is intended for use with non-corrosive, non-flammable, and non-hazardous gases. The device is compliant with ISO 4414:2010 standards and MSHA regulations 30 CFR 56.13021 and 57.13021.
Installation and Compatibility
The HOZE-FUZE® is designed for straightforward integration into existing pneumatic systems. It is crucial to match the device size with the hose’s inner diameter to ensure optimal performance. For instance, a 3/8″ HOZE-FUZE® should be used with a 3/8″ hose. Avoid using reduced fittings downstream of the device before the tool to maintain safety and functionality.
By incorporating the ROSS HOZE-FUZE® 1969A3001 into your pneumatic setup, you enhance workplace safety by effectively controlling potential hazards associated with hose failures.
