Roots blower Features (1) constant volume fan, no internal compression, transmission of gas mandatory, Tianjin blower, with the pressure changes, Shenyang blower, the flow changed little. (2) products using clover straight impeller, intake and exhaust pulsation smooth, low noise. (3) The impeller with a special curve to make more rational engagement, disclosure, high efficiency, low energy consumption, is a new energy-saving products. (4) The product uses a variety of new structural design, compact structure, small size, light weight, elegant appearance. (5) The product uses high-precision hardened synchronized gears, long life, low noise. High-speed miniaturized. Ternary flow impeller to improve efficiency, Roots blower, leaf blower can significantly reduce the size and weight. Contemporary latest technological achievements while improving the one leaf blower speed is an important way to miniaturization, the new impeller materials, liquid gas seal rotary power, high-speed gas bearings and magnetic suspension bearings for high speed miniaturized leaf blower create good conditions.
