Household range hoods are mainly composed of fan system, control system, oil filter device, casing and suspension device. The fan system is the heart of the range hood, usually composed of a motor and an impeller. The power of a range hood is also determined by the fan system. Determined, the control system is the most scientific and technological component of the hood. There is a microcircuit board to control the power and switch of the hood. The oil filter device mainly refers to the oil screen and oil filter chamber. Made of high temperature and corrosion resistant materials.
