Design Advantages
- Light weight - carry more materials in the tank not more compressor on the tank-truck. Greater operator profits
- High efficiency - Less power/fuel for operation, lower temperatures for reliability, wider flow range for versatility. Lower operating costs, flexible tank-trucks
- Compact - Mounts inside the chassis for direct drive on 4 x 2 trucks. No belts required, large fuel tanks possible. Less maintenance, lower installation costs
- Coated rotors - high corrosion resistance design. Reliable performance with low service costs
- Gravity lubrication - No oil pump to go wrong
- Simple to install - CW or ACW input drive rotation and either side discharge port make the machine easy to install. Faster, cheaper installations
