Feature Product Features -- The shaft is low resistance and high efficiency. -- The life span is L10 80000 hours without lubricating. -- The unit keeps running under the wind velocity less than 2m/s. -- Low profile blades, elegant lines Smooth airflow. -- Stainless steel scroll wheel, corrosion and rust resistant. -- With integral variable-angle neck, angle can be adjusted if the curb is not flat. -- The hood is flexibile ,stale running. Special design of fan blades enlarges the contacted area and angle with wind. The rotation power shall be strengthed in the wind; The high speed scroll produces even bigger centrifugal force and stirs the air to form negative pressure, making the airflow rate speeds up to ensure good effect of ventilation. -- Integral curb cap prevents leakage and for easy installation. -- The elegant silver design of the unit complements any building’s appearance. -- Scroll hood is compacted with throat for preventing rain into room.

Technical Typical Application -- Industrial workshop gravity rooftop exhaust. -- Inlet/outlet of duct system. -- Outlet chamber of heat-producing appliance. -- Outlet for pressurized industrial building. -- Inlet for negative pressurized industrial building. -- Inlet of workstation make up air.
