FIELD: mechanical engineering.
SUBSTANCE: invention relates to an exhaust fan with a double inlet. The exhaust fan includes a main body containing an upper end with an air intake hole, a casing located above the upper end of the main body. The fan also includes a motor-fan assembly located in the main body. The casing is separated from the opening of the main body by the first distance so that a side inlet for air intake is formed between the casing and the opening of the main body. The casing has a central opening partially covered by a central lid. In this case, the central lid is separated from the central opening of the casing by a second distance, so that a frontal inlet for air intake is formed between the central lid and the central opening of the casing.
EFFECT: invention is aimed at improving the efficiency of ventilation.
