EVSC-S21A3

The EVSC-S Single Stage Side Channel Blowers

The EVSC-S Side Channel Blowers are Single Stage Blowers and therefor used in applications that require a high air flow. These pumps are designed for industrial applications and can run 24 hours a day. They require little maintenance and are easy in use. They are universal build to run in Vacuum or Compressed Air applications. When using the Blower for a vacuum application the inlet should be connected to the application and the exhaust blows into the atmosphere. When used for compressed air applications the inlet should be connected to the atmosphere and the exhaust will be able to supply compressed air to the system. It is highly recommended to use a pressure limitation valve in both applications. The EVSC-S Blowers will be found Worldwide in these applications :

  • Pneumatic conveying, Filling of bags/bottles/hoppers
  • Lifting and holding of parts by vacuum
  • Aeration of sewage-treatment plants, Aeration of fish ponds
  • Thermoforming, Packing machines
  • Sorting/enveloping of letters, Paper processing
  • Food-processing, Textile machines
  • Dental suction equipment, Gas analysis
  • Printers/copiers, Laser printers
  • Swimming pool equipment/whirlpools
  • Soil remediation
