Products Introductions & Advantages for Oil-Free VSD Air Suspension Centrifugal Blower:
Air suspension centrifugal blower is a single stage centrifugal blower, without gear box, without speed booster and coupling, driven directly by high-speed permanent magnet motor, and the motor adopts frequency converter to speed regulation. The blower impeller is directly connected with the motor rotor, the whole is suspended in the air bearing, no physical contact and lubricating oil system, so the air suspension centrifugal blower has the characteristics of high efficiency, energy saving, low noise, reliable operation and long-term operation without maintenance etc.

 

Safe And Stable

At the same time, its high energy conversion rate also enables the equipment to achieve energy-saving effects during operation. As the core component that acts on the air, the centrifugal impeller sucks in a large amount of air and quickly discharges it when it rotates at high speed, greatly increasing the air pressure and ensuring that the gas can be delivered to the desired location with sufficient pressure and flow rate. The design of the snail shell is also very clever. It bears the important responsibility of collecting and guiding airflow, cleverly converting the kinetic energy of the airflow into pressure energy, further improving the efficiency of gas transportation.

Good Sealing Performance

Our Oil-Free Air Suspension Bearing Centrifugal Blower is widely used in the sewage treatment industry to aerate sewage tanks, providing sufficient oxygen for microorganisms in the sewage to fully contact with substances in the sewage, effectively decomposing pollutants in the sewage and achieving good sewage treatment results. In industries such as cement plants, chemicals, and food, it can be used for pneumatic conveying of industrial raw materials, dust, and food. By ensuring stable and efficient gas delivery, the smooth progress of the production process is guaranteed.
