Principle Blowers increase the kinetic and static pressure energy of gas via mechanical motion to gas delivery.

Basic principle: A motor drives the impeller or rotor to rotate at high speed, drawing in and accelerating air.

Kinetic energy is then converted into pressure energy inside the volute/housing before gas discharges from the outlet.

Regulation method: Modern blowers adopt variable frequency speed control. Air volume and air pressure are adjusted by changing motor rotational speed.

Delivering higher energy efficiency compared with traditional throttling regulation.

Core components: Motor, impeller (rotor), housing, bearings and control system. Some units are fitted with air filters and silencers.

Types Classified by working principle and construction; selection depends on pressure, air volume and site operating conditions.

Roots Blower: Positive displacement blower. Two lobed rotors rotate oppositely inside the cylinder to deliver gas.

Air volume; ideal for water treatment aeration and pneumatic conveying.

Centrifugal Blower: Gas is pressurized by centrifugal force.

Available in single-stage and multi-stage versions with high efficiency; used for blast furnace air supply and chemical gas transportation.magnetic levitation Blower: uses magnetic levitation bearing technology.

Zero mechanical wear, low noise and high energy efficiency; mainstream equipment for wastewater treatment industry.

Small high pressure Blower (Vortex Blower): Delivers pressure severalfold higher than centrifugal blowers. Compact footprint.

For printing, packaging and environmental protection machinery.
