Features

Two Rotors with lobe curve optimized ensures no leakage inside blower, improves blower’s efficiency. Radius-center distance ratio is narrowed and shaft’s diameter is enlarged. There\'s no deformation and collision will occur under higher load pressure as the blower’s strength is improved. Unique hollow design of end-cover is used for making bearing cavity separated from gas chamber relatively, by which reduces the impact of inside high temperature gas on bearing cavity and lowers the bearing temperature. Deep groove ball bearing of high precision and low friction factor is selected for lowering operation noise. In addition, because of larger size bearing matched for enlarged shaft diameter, the bearing’s load capacity is enhanced and its service life is extended. A structure of 90 degree upper inlet and side outlet is adopted for convenient installation and maintenance. Different silencers are available for customers’ needs of saving floor space.
