Integral structure of impeller and shaft without shortcomings of split structure.
Optimized lobe curve is adopted for reducing blower's internal leakage, improving blower's efficiency and reducing running temperature.
Thanks to its narrowed radius-center distance ratio and enlarged shaft's diameter, no deformation and collision will occur under higher load.
Unique hollow design of end-cover is used for separating bearing cavity from gas chamber relatively, by which the impact of inside high temperature gas on bearing cavity is weakened and the bearing temperature is lowered.
Deep groove ball bearing of high precision and low friction factor is selected for lowering operation noise. In addition, the bearing of enlarged size is of larger load capacity and longer service life.
Horizontal installation with same inlet and outlet structures is favorable for saving floor space.
Type
Rotary Lobe Blowers
One specific kind of positive displacement blower is the rotary lobe blower. This operates by way of dual rotors which rotate in opposing directions. The blower draws in air, and the lobes spin the air around before impelling it outward.
Helical Screw Blowers
Helical screw blowers, much like centrifugal blowers, are able to produce air at higher pressures than rotary lobe blowers. Helical screw blowers utilize two rotors, which are each equipped with lobes (usually two or three).
Centrifugal Blowers
Centrifugal blowers are typically used in applications where there is a need for high pressure and variable flow. These blowers have rotating impellers, which increase the speed of the air (or gas) as it passes through.
High-Speed Blowers
Designed for high-pressure (up to 25 psi) and high-flow (up to 15,000 m3 per hour) demands, high-speed blowers are powered by a motor. Similar to centrifugal blowers, high-speed blowers have impellers at each side which provide dual suction.
Applications
Wastewater Treatment
Used in aeration systems, pneumatic conveying, and other related processes.
Industrial Gas Transport
Widely used in industries such as chemicals, power generation, and steel manufacturing.
Ventilation & Exhaust Systems
Applied in tunnels, mines, and construction sites for ventilation and air exchange.
Vacuum Systems
Commonly used in packaging and food processing for vacuum extraction and packaging machinery.
