Rosenberg presents the high efficiency fan with backward curved blades, with electronic switching motors with power of 5,5 kW, in models of 450 mm, 500 mm and 560 mm, with full speed control, suitable for a wide range of applications in HVAC and for air mobilization.
This equipment can generate up to 7 inches of static pressure or up to 10.000 cubic feet per minute of air stream and its impellers are made with saltwater proof steel, balanced according to quality standard G 2.5, DIN / ISO 1940.
These fans also have other features, such as closed protection motor class IP 44 / 54, for greater reliability in humid environments, thermal contacts connected in coils for motor protection and standard ball bearings, maintenance-free.
The fans with backward blades use motors of reduced mechanical content, which allows them to operate generating less temperature and low noise, in addition to being approved by CE, UL and RoHS. Additionally, these equipment can be customized with specifications requested by the customer, including air flow, power, rotation speed, noise level, housing dimensions and finishes.
