Range hood variable frequency fan

A household range hood primarily consists of a fan system, control system, oil filtration device, housing, and suspension device. The fan system is the core component of a range hood and typically consists of a motor and an impeller. The power of the range hood is determined by the fan system. The control system, with its microcircuit board, controls the power and switch of the range hood, making it the most technologically advanced component. The oil filtration device mainly refers to the oil mesh and oil filtering chamber. The housing and suspension device are usually made of stainless steel, a material known for its high temperature resistance and corrosion resistance.
