Important Safety and Operational Considerations

Roots URAI-G gas blowers are designed for handling gases, including potentially hazardous gases such as combustible or toxic gases. It is the responsibility of the system designer and end user to ensure proper safeguards are implemented for safe installation, operation, and maintenance.

These blowers utilize mechanical seals instead of typical lip seals to minimize gas leakage into vented oil-bearing chambers. Some level of leakage may still occur, and purge systems can be used between the headplate seal and mechanical seals to help mitigate this.

System design and operation must comply with all applicable codes and standards. The manufacturer is not responsible for the effects of corrosion, erosion, or material build-up. Refer to the instruction manual for complete operational guidance.
