RSS Roots Blowers & EV Roots Blower

EV series 3-lobe roots blowers are researched and developed on a basis of RSS series. The biggest feature of this blower is high rotation speed (the maximum can be 4000RPM)、high capacity. With the breakthrough of technology and the modification of practical application, EV series blowers have higher efficiency、higher pressure、lower weight and other features. The inlet sizes are from 2.5”to 12”.The pressure of single blower can be 1 Kgf/cm2. EV series features : ●High efficiency Great ructure, reduce sectional area of rotors to improve capacity of blowers. ●Low vibration High grade of balance accuracy (G2.5) can control the vibration of X、Y、Z coordinate. ●Low loss of pressure 180 degrees vertical structure between inlet and outlet, reduce its pressure loss of blowers. ●High vacuum The vacuum of single EV blower can be -500mmHg, and the two-stage EV blower can be -650mmHg.
