Cast Iron Roots Rotary Lobe Blower,  capacity 3600m3/hour  roots lobe blower
Roots blower is a kind of volumetric blower whose air capacity and revolution have formed a proportion. Each rotation of the three-lobe type blower needs three times of air suction& discharge of two-lobes. Compared to two-lobe type blower, three lobe roots blower have the characteristics of low air pulsation and more stable operation.
It has two lobes on the two parallel bearings. There are small tiny spaces between lobes, elliptic casing as well as each lobe. he lobes' uniform speed rotation at opposite directions makes the certain quantity air circled by casing and lobes transported form the suction side to the discharge side.
