VASF 2 series

Side channel blowers, single stage & gas-tight

Becker VARIAIR Speed Flow (VASF) series side channel blowers generate suction or pressure for a wide variety of industrial applications. These compact vacuum pumps and compressors with variable frequency up to 300 Hz offer high performance in a quiet, contact-free environment. 100% free of oil and contact during operation, these pumps are low-maintenance and highly efficient.


Each VASF 2 series pump comes standard with:

  • VARIAIR frequency inverter
  • Additional cooler
  • Vibration isolators for horizontal installation
