Description
Side channel (regenerative or ring or Vortex) blowers. These blowers are also called regenerative blowers. Side channel blowers function as vacuum pumps or air delivery blowers. They can generate significantly higher pressures than industrial fans. They are used for both vacuum and pressure applications. Regenerative Blower are dynamic compressors, in which a rotating impeller drives the air and creates/maintains the pressure. These blowers run on bearings and have no other wearing parts. They are a good choice for aerating water and so widely used in water applications, such as sewage treatment, aquaponics, hydroponics, aquaculture etc.
See the blower curve and data table. The maximum pressure (or vacuum) is the sum of all pressure requirements: water depth, pipe distance, pipe diameter, air diffuser system design, bends, valves and altitude.
1/2 meter of water = 50mbar. Adjustment for a Johannesburg altitude compared to the coast is a factor of 1.2 = 60mbar at 1573m. So, generally this blower is recommended to up to 0.8m of water, giving some allowance for friction losses and altitude. Advised delivery pipe diameter for 10m of pipe between the blower and air delivery is 65mm.
