The RB-DV series of rotary lobe blowers are equipped with air injected cooling systems, allowing continuous operation even in the most challenging, heavy duty waste collection applications, in both dry and waste liquid products.

A tri-lobe design that offers a unique solution for both dry and liquid waste applications. What sets the RB-DV apart is its compatibility with hazardous and sensitive materials, including ADR-classified substances and chemical waste. This makes it an ideal choice for industries that require both performance and safety.

With RB-DV’s patented air injection system, these blowers ensure cooler operating temperatures, exceptional efficiency, and industry-leading noise reduction. Running on a dead-head means the blower operates at its maximum vacuum level without any airflow. This is critical capability for applications that require deep vacuum, such as hydro excavation and oil field work, without the need for additional cooling systems like water injection or heat exchangers.

Troubleshooting Blowers

Possible Causes

  • Clogged Filters: Dirty or clogged filters can restrict airflow.
  • Rotor Issues: Worn or damaged rotors can reduce efficiency.
  • Air Leaks: Leaks in the system can cause loss of airflow.

Solutions

  • Clean or Replace Filters: Regularly clean or replace filters to ensure optimal airflow.
  • Inspect and Replace Rotors: Check for wear or damage and replace rotors as needed.
  • Seal Leaks: Tighten connections and replace any damaged seals to prevent air leaks.
