China products/suppliers.Ce, ISO9001, SGS Approved Roots Blower 10-80kpa Roots Type Blower
About BK Three Lobes Roots Blower
BK series roots blower, with the intergral structure of impeller and shaft, has a waide application in environmental protection, electric power, architecture, gas supply and etc.
Main Chrarcteristics
1) Working smoothly as helical timing gears is adopted.
2) It is flexible mounting ways because of the same structure in inlet and outlet.
3) It adopts more reasonable bearing structure, which can incresase the bearing operation life.
4) It is low noise, vibration and energy consumption.

Working Principle
Roots blower is a cubage blower, and it discharges a fixed amount of air in proportion to its rotation speed. Every rotation, there is two lobes to finish three times absorbing and dischargeing air. Compared with two lobes blower, it is of less air pulses, smaller load change, higher strength, lower noise and vibration.
Two paraller shafts have three lobes each, all the lobes keep small clearance with each other and housing inside. Every lobes rotatiomn, a certain air will be absorbed at inlet and transfeered form the housing inside surface to blower's diacharge port.
Two shafts will be turned by the timing gears, no any touching between lobes, so it can be turned at high speed without any lubrication inside. It has the following chaaracteristics: simply configuration; running smoothly;good performance stabilization. It has been widely applied in various industries.
Applications
Water treatment: Roots blowers find applications in water treatment facilities for processes such as aeration in water and wastewater treatment, ozone generation for disinfection, and providing air for dissolved air flotation systems.
Wastewater treatment: Roots blowers are commonly used in wastewater treatment plants for aeration purposes. They provide the necessary air supply for the biological treatment processes, such as activated sludge systems, where microorganisms break down organic matter in the wastewater.
Aquaculture and fish farming: Roots blowers are utilized in aquaculture and fish farming systems for aeration and oxygenation of water. They help maintain optimal dissolved oxygen levels for aquatic organisms, promoting their growth and survival.
