PWM / 0~10V backward centrifugal fan AC DC EC centrifugal blower fan industrial ventilation centrifugal fan
Product Description
- Mainly used in grain drying and and greenhouse ventilation. These are also common in air pollution control as well as heating, ventilation and air conditioning (HVAC) systems.
- EC backward curved motorized EC impeller is a superbly crafted, precision balanced air-moving device that features superior performance and compact design.
- By combining the efficiency of a backward curved centrifugal impeller with the advanced technology of an electronically commutated external rotor Motor, new standards for energy savings and performance have been achieved.
