Farm building fan SERCO HVLS

for air circulationceiling

The Serco HVLS fan system provides high-quality velocity cooling for all types of livestock. The variable-speed operation allows for the system to adjust based on current temperature conditions in your barn. In addition, the reverse operation function blows air upward which mixes the layered heat throughout the barn in cold weather. The HVLS design means that the fans run at a very low speed which reduces the noise level well below that of high-speed fans. The HVLS fan system is available with a stand-alone thermostat controller for automatic variable speed adjustment. They can also be operated with the Unity NATVENT Control which can be used to operate your natural ventilation system as well. • Optimized 5 blade profile for low-speed rotary airfoil application and near ground effect. • Large air current depth - horizontal floor jet of 3-9 ft (1-3 m). • NACA airfoil profile reduces drag while producing more airflow. • Standard black corrosion-resistant anodized blades. • Fan safety system includes guy wires and safety cable. • Patent-pending aluminum hub and blade support system. • High-efficiency variable frequency drive (VFD) • Adjustable speed control panel with forward / off / reverse switch, self-diagnostics and 4 digit passcode protection. • Aerodynamic blade winglets with patent-pending design and made from high-density polyethylene (HDPE). • Supplied with 25 feet of power cable pre-wired to fan motor (connection to power source by others.) • UL certified motor and controls. • Fused disconnect and line reactor standard.
