Roots blowers are used in numerous industries and industrial processes, including pneumatic conveying. Roots blowers play a vital role in many manufacturing and processing systems. Roots blowers are technically known as "positive displacement rotary blowers" and are commonly referred to as "blowers". What does a Roots blower do? Roots blowers are used to produce a constant airflow that is independent of the exhaust pressure conditions. The application of Roots blowers is limited to low and medium pressure and vacuum processes, and can be used to provide small to large airflow rates. How does a Roots blower work? Roots blowers consist of two identical and symmetrical rotors with two or three meshing blades in a sealed housing. The housing is valveless, and the air inlet and exhaust ports are usually located on opposite sides. The rotors rotate in opposite directions and are synchronized using a set of gears. The air is displaced from the inlet to the outlet by the movement of the meshing blades on the counter-rotating rotors. The airflow rate produced by the displacement is mainly determined by the rotational speed of the rotors within the Roots blower. There is no change in the amount of air within the Roots blower, so no air compression occurs. Roots blowers are typically air-cooled, and some models do not require oil as a lubricant (oil-free).

We've been designing and manufacturing air blower for 17 years since 2007. Located in Shandong, China, We supply 3 lobes roots blower/vacuum pump, air bearing turbo blower and also rotary vane type blower etc., applying in wastewater treatment, cement factory etc., providing air for the aeration of water. What we can offer: 1, High precision. Equipped with HMC and CNC machine, all the critical components of the blower are produced quickly and accurately under ISO9001 standard. 2, Stock. Regular models are stocked and customized orders only needs 5-7 days to finish. During 3 years covid, we try our best to cut down production time to help our client get quick capital turnover. 3, Less repair. Every set will be under a run-test at least 12 hours under max pressure. It is EVERY SET, not sampling check. Avoiding any sudden situation may happen when clients receive the blower.
3 Lobes roots type air blower for wastewater treatment
Rotary Air Blower Product Description The Rotary Air Blower utilizes an involute profile integral shaft ductile iron impeller design. The head plate, gear cover, end caps and rigid one-piece housing are made of gray cast iron. Carburized and ground alloy steel timing gear tapers are mounted on the shaft and secured with locknuts. Cylindrical roller bearings are used on the drive end and ball bearings on the gear end. The characteristics and advantages of rotary blowers 1. Small size, large air volume, low noise, and low energy consumption (the rotary blower adopts the principle of operating compressed air, although small in size, it has high air volume, energy saving, and operates quietly) 2. The operation is smooth and the installation is very convenient (for small models, as long as they are placed properly, the vibration is minimal and there is no need to install anti vibration devices, making the installation very convenient). 3. Resistance to load changes and stable air volume (for example, if the pressure of the sewage treatment aeration tank changes, the load changes, but the air volume also changes very little with the pressure change). 4. Equipped with an air chamber for smooth air dissipation (all models are equipped with an air chamber to prevent air pulsation and ensure smooth air dissipation). 5. The material is excellent, the structure is clever, and the performance is excellent (all blowers are made of high-quality materials, the structure is exquisite, sturdy and durable, and the performance is excellent, with few faults occurring during long-term use). 6. Simple maintenance, few malfunctions, and long service life (low speed, low wear, and long service life).
Centrifugal Air Blower Centrifugal Air Blower For Sale Centrifugal air blowers adopt three core high-end technologies: "ultra high-speed direct connection motor", "air suspension bearing", and "high-precision single-stage centrifugal impeller", creating a new era of high efficiency, high performance, low noise, and low energy consumption fans. It is a new generation of high-tech civilian products developed with great dedication based on the design experience of aviation turbomachinery. Features 1. Energy saving and high efficiency The air suspension centrifugal blower uses air bearings, direct connection technology, a high-efficiency impeller, a permanent magnet brushless DC motor, and no additional friction. The fan automatically adjusts the consumption of motor power based on the output (adjustable range of air volume 40-100%) to maintain the high efficiency of equipment operation. 2. No vibration, low noise Adopting air bearings and direct connection technology, there is no vibration generated, and the fan does not need to be equipped with sound insulation devices; The equipment is lightweight and does not require a special foundation. The installation and layout are simple and flexible. 3. No lubricating oil The fan adopts air-bearing technology, and the system does not require a lubricating oil system, providing clean air to special industries such as electronics, medicine, and food. The operating temperature of the air bearing has reached 600 degrees, and all the drawbacks of the oil-based bearing system have been successfully resolved. 4. No maintenance Without the necessary gearbox and oil bearings for traditional fans, our series of high-tech impellers and motors are directly connected without couplings. The intelligent control system and key components use AL7075 (aviation aluminum). These technologies ensure that the equipment is maintenance-free, reduce maintenance costs for users, and improve the stability of the gas supply system operation. 5. Convenient operation control Self-checking and constant pressure operation, load/no load operation, overload control, and unmanned operation can be achieved on a personal computer for fan speed, pressure, temperature, flow rate, etc. The fan adjusts the flow rate by adjusting the speed of the impeller. Adjusting the speed can easily adjust the flow rate based on the temperature and pressure changes of the inhaled air. It can automatically and manually adjust the flow rate. 6. Small device installation space The air suspension centrifugal blower equipment is lightweight, small in size, easy to install, and can significantly save users on building and auxiliary electrical control system investment.
Roots Blower For Sale The Roots blower is a volumetric fan, with impeller end face and front and rear end covers of the fan. The principle is to use two blade shaped rotors to move relative in the cylinder to compress and transport gas in a rotary compressor. This type of blower has a simple structure and is easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement conveying, and is more suitable for gas conveying and pressurization systems in low pressure situations. It can also be used as a vacuum pump, etc. Type of Roots Blowers for Sale Roots Vacuum Pump Roots vacuum pumps have been applied in petroleum, chemical, plastic, pesticide, turbine rotor dynamic balance, aerospace space simulation and other devices, so they should be vigorously promoted and applied in China.
