JRSA axial flow roof fan

1、 Characteristics and Applications

JRSA axial flow roof fan, also known as roof axial flow fan（roof fan）It is a new type of roof air supply fan jointly developed by advanced technology from Europe and America and research schools. The streamlined flat wind cap with multiple reinforced ribs is designed with high strength to increase wind resistance, making it more suitable for building ventilation in areas with high wind or rain and snow loads; Adopting high-quality wing shaped high-efficiency axial flow impellers, direct drive, high efficiency, smooth operation, and the motor is fully cooled inside the airflow; The hood can be assembled on site, saving on lifting and transportation costs. This series of roof fans has the advantages of high air volume, moderate pressure, low noise, low power consumption, and compact structure. They are widely used for roof air supply (explosion-proof air supply) in industrial plants such as power plants, paper mills, machinery, and building materials.
JRSA (RSA/RTA) series fans are generally used for roof air supply, but can also be specially manufactured for roof exhaust.
According to different usage environments and conveying media, conventional, fiberglass roof fans, and explosion-proof and anti-corrosion roof fans are made.
Optional accessories: Gravity (or electric) check valves, bird (insect) nets, maintenance switches, centralized control boxes, air caps with plate filters, and other accessories can be installed as needed
