Side channel blowers, also known as regenerative blowers or ring blowers, are devices used for moving air or gas with moderate pressure. They are commonly employed in applications that require continuous airflow and a vacuum or pressure, such as pneumatic conveying, vacuum lifting, aeration, and more.
Key Features:
- Operating Principle:
- Side channel blowers work by trapping air in the space between the blades of an impeller and the housing (side channel). The impeller rotates, accelerating the trapped air, which creates a pressure increase as the air moves along the channel.
- Non-Contact Design:
- The impeller does not touch the housing, so there’s no wear due to friction, leading to low maintenance.
- Pressure and Flow:
- These blowers provide higher pressures than centrifugal fans but lower flow rates than typical industrial blowers.
- They can generate pressures up to 1,000 mbar (14.5 psi) and vacuum up to -500 mbar.
- Typical Applications:
- Pneumatic conveying: Used to move granular materials like powders and grains.
- Wastewater aeration: Provides oxygen in water treatment processes.
- Vacuum lifting systems: Used in packaging or handling to lift objects via vacuum suction.
- Cooling and drying systems: Help to cool or dry products in industries like plastics, paper, or food processing.
- Advantages:
- Oil-free operation, making them suitable for clean air applications.
- Low noise levels and vibration.
- Compact design and easy to install.
