The outer rotor backward inclined centrifugal fan has no housing
The outer rotor backward inclined centrifugal fan has no housing, which is convenient to support various purification HVAC equipment and is installed in the inner frame of the equipment.
The fan rotates to produce centrifugal air flow. When the air flow meets the inner frame wall, it forms a very high air pressure, so that continuously passes through the filter element layer to form a coaxial flow direction. The outer rotor backward inclined centrifugal fan has high pressure, large air volume and obvious effect, It is a better choice for small HVAC equipment. The fan is composed of external rotor, asynchronous motor and aluminum impeller.
The motor has the advantages of low temperature rise and ventilation, heat dissipation and self cooling. So as to prolong the service life and reliability of the fan. The fan is a backward curved impeller, which has the characteristics of compact structure, large air volume, high static pressure, low vibration, low noise, convenient installation and so on. It is mainly used for supporting refrigeration equipment such as purification workbench, purification unit, ventilation pipe dust removal, purification air conditioning system, environmental protection and pollution control.Most motors have compact structure and good heat dissipation under high voltage conditions.
