Cast Iron Atlas Copco Air Blower, 20 HP

DB Series Side Channel Blowers Introducing the Atlas Copco DB series Side Channel Blowers - a tested and reliable technology for rough vacuum level and low pressure as well, suitable for industrial application in the most efficient way possible. Available in single and double-stage variants the DB series do not require oil to operate. This ensures a clean operation, free of emissions and no contamination to the process. They are designed to be robust, clean, compact, and silent suited for rough industrial applications with high efficiency. The modular construction of DB side channel blowers ensures efficient performance with minimal energy consumption. DBDt - Twin impellers and double stage Double stage and twin impellers allow to manage high flow rates and higher vacuum levels. They are the most complex models to match demanding applications. The double stage variant increases both the pressure difference and the flow rate of the blower. DBSt - Twin impellers and single stage The twin impellers working in parallel allow for large quantities of suction air up to 1980 m3 /h with discrete vacuum levels up to -300 mbar. The twin impeller variant increases the flow capacity of the blower. DBS - Single stage and single impeller Ideal for applications requiring flow rates up to 1000 m3 /h for regular vacuum levels up to -350 mbar. DBD - Double stage and single impeller Ideal for applications that need limited flow demand with vacuum levels up to -450 mbar. Working principle Side channel blowers operate by transferring kinetic energy through a rotating impeller. The impeller, available in single or twin variants, are direct fixed to the motor shaft enabling (direct driven transmission) suction for the pumped medium. This is subsequently compressed in the side channel. Available in single and double-stage variants, the DB series can be used to generate both vacuum and compressed air with capacities and differential pressure as needed for your process. A
