Pressure and Vacuum


CFW Fans provides high-pressure blowers for creating relatively high positive or negative pressures.

Whilst all fans develop pressure and 'vacuum' in order to move gases, the realm of 'pressure' and 'vacuum' really falls into the category of high pressure blowers.

These include single and multi-stage centrifugal blowers and side channel (regenerative) blowers.

Typical high pressure or 'vacuum' applications include:

  • Fluid aeration: Aquaculture, wastewater treatment, water sterilisation etc.
  • Fluid agitation: Compost tea, chemical mixing, plating tanks, spa baths etc.
  • Pneumatic conveying systems
  • Air knife systems
  • Fluidised beds
  • Automated bottle filling systems
  • Soil remediation
  • Vacuum tables
  • Medical suction systems
  • Product conveying: Plastics manufacture, pneumatic capsule etc.
  • Vacuum lifting systems
  • Combustion Air

CFW stocks a wide range of imported side channel blowers and manufactures high pressure centrifugal blowers at our Cape Town works.

  • Lateral Channel Blower
  • BC-HT & RB-HT Blowers
