150KPA Roots Air Blower, two stage, DN300, two stage roots air blower
 
 
About BKD
 
BKD series is a two-stage roots blower.  A middle cooling system is installed between the first and the second stage blower, which will cool the temperature of airflow out from the first stage blower,  and then the temperature of airflow into the second stage blower will be normal and will not damage the blower. By the two stage compression, BKD blower can reach the maximum pressure of 150KPA.
