features:

•  low noise and vibration as a result come from dynamic balaning
•  directly connected motor shaft -impeller provides reliable long term performance

wooring principle

•  ring blower impeller contain numerous blades in its edge and it is special designed for a high air pressure
• when the impeller rotates .as centrifugal effect the air between two blades be transferred rapidly to the edge gain higher speed
• after coming back into the impeller again thought the channel or blower .the air transferred again and speed again
• since numerous blades help transfer energy.the air pressre increases progressivery and present high air pressure.
