Semi-open vortex
・Special open type vortex impeller permits foreign matter passing the inlet port to be freely discharged.
・As the passage size is uniform from the inlet port to the discharge port, the size of passed foreign matter can be as large as the port diameter.
・4 pole induction motor runs with high torque to enhance foreign matter passing.
・Built-in motor protector (automatic cut-off for model below 7.5kW and thermal protector over 11kW) protects the motor from overload or open phase.
・Optional quick discharge connector facilitates easy installation and maintenance.
・DVA model permits automatic operation.
Parallel alternate operation possible with model DVA and DVJ.
