About Blower

Blower (English: Blower, Blowing fan, Fan) is a general term for devices that send out air. Strictly speaking, according to the Japanese Industrial Standards (JIS), it is defined as "a machine that gives energy to a gas through the rotational motion of an impeller, and whose energy per unit mass is less than 25 kNm/kg (kJ/kg)." increase. In this standard, "blower" and "fan" are synonymous, and are distinguished from "blower" or "blower" that pumps gas with an impeller, rotor, and piston. However, in the industrial field, there are few clear distinctions as described above. Those with relatively weak discharge pressure are called "fans", those with relatively strong discharge pressure are called "blower" or "blower", and "ventilators" are called "fans". These are often used collectively.
