Aerator, aeration and blower prices - side channel blower

Generalized and specialized blowers based on air volume and pressure requirements

We supply blowers for general applications, such as aquaculture and more specialized blowers for precise volume and pressure requirements. These blowers are know as side channel or regenerative blowers. Side channel blowers, also known as vacuum pumps or vacuum compressors, can generate significantly higher pressures than industrial fans. However, a side channel blower generates lower air flow than, for example, centrifugal fans.

Please see the blower curve selection of the specialized and wide range of blowers.

Due to rapidly changing exchange rates, most prices are supplied on request

The Rand volatility means for us that prices vary too much to maintain too many prices. Please  email us  for other prices, based on your air volume and pressure requirement.

Blowers in stock

Prices exclude VAT and delivery. Prices exclude air intake filter. Many other blowers are available, as we select your blower for your specification, so please send us your blower requirement.
