Centrifugal fans
VAKUO specializes in the custom design manufacture of centrifugal fans to meet the requirement of the paper industry. The fans are available in a wide range of diameter and width, to handle :
- suction capacities up to 500 m3/min
- vacua up to -20 KPa (single stage)
The fan housing, or casing, is manufactured from welded stainless steel plates. The wheel, or impeller, is made of stainless steel blades mounted around a hub and welded to the backplate. The blades can be arranged in three different ways: forward-curved, backward-curved or straight radial.
Our BL ("backward bladed") series are the most efficient and cost effective fans for our applications in the paper industry with both saturated / wetted air and light dust loads.
The fans are direct driven: the fan wheel is linked directly to the shaft of the motor.
Backward curved fans are energy efficient in a wide range of speeds and can be used with a variable speed drive (frequency converter) for a better overall energy efficiency.
