About BK-3
 
Roots blower is a displacement 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 discharging air. Compared with two lobes blower, is is of less air pulses, smaller load change, higher strength, lower noise and vibration.

Features

Uniquely designed shaft and lobe curves reduces air leakage and promises reliable performance. Vertical type of compact structure for easy installation and convenient maintenance Hollow design of end-cover reduces the impact of inside high temperature on bearing cavity and prolong the bearing service life. Large size bearing of improved load capacity is used for matching the size of enlarged shaft diameter.
