The Roots fan is a gas conveying device that works in positive displacement and has a relatively simple structure, but plays an important role in industry. Its working principle is based on the rotation of two rotors in the same axial direction, creating gas intake and discharge. During the operation of a Roots fan, the gas is first drawn in through the air inlet. As the two rotors rotate, the gas is trapped between the rotors and the housing and is pushed towards the outlet in the direction of rotation of the rotors, ultimately forming the discharge of the gas. Because of their unique design, Roots fans are able to provide a steady flow of gas and maintain a high level of efficiency even at high pressures. Application scenarios of Roots fans in various industries Roots ...
