POSITIVE/NEGATIVE PRESSURE FORMING SYSTEM USING ROOTS BLOWER

摘要

PROBLEM TO BE SOLVED: To provide a positive/negative pressure forming system using a Roots blower improving energy efficiency.;SOLUTION: Both of positive pressure and negative pressure are formed by arranging a suction side accumulator 2 on a suction side of the Roots blower and a discharge side accumulator 3 on a discharge side of the Roots blower. On a positive pressure side, that is, a side discharging air can blow off dust or metallic dust by using the discharged air. On a negative pressure side, that is, a side sucking the air can constitute a vacuum cleaner by using the sucked air.;COPYRIGHT: (C)2006,JPO&NCIPI
