Renewal of blower equipment

The following is an introduction to technology for converting from rotors to high-efficiency impellers and for modifying capacity control from suction valve to inlet vane, as a measure to support energy efficiency to prevent global warming.

Reduce axial power by using high-efficiency impellers

The efficiency of new impellers developed in 2001 has been further increased, so efficiency improvements of 5 to 10% have been achieved compared with blowers supplied prior to 1982.

Optimal control using inlet vane

Capacity control over a wide range has been achieved by the combination of the optimal inlet vane design and high-efficiency impellers.
Good capacity control under partial load can be achieved using an inlet vane flow rate control device provided on the impeller inlet.

Implementing energy efficiency proposals in accordance with customers' needs

• Blower replacement
• Proposal for modification to a high-efficiency rotor using the same blower casing, etc.
