Series HF AEROMATIC High Efficiency Centrifugal Air Blowers / Fans are a new concept in Fan Engineering. Each type 14 to 40 has different specific speed for best efficiency. Each type has various sizes selected from basic log series of preferred numbers. This has made it possible to select the best type and size for a given speed, capacity and pressure. Selection of SWSI / DWDI / Multistage is based on specific speed for a suitable type for best efficiency. |

Shafts are on EN - 8 steel properly sized to keep away from critical speed. |
|
Bearing Life: |
|
|
|
» |
Bearings are designed for Long Life. This life can be attained when properly lubricated, kept clean, tensioning belts correctly and keeping Impeller clean and balanced. Smaller vee pulleys and improper belt tension reduces the life considerably. Proper care and lubrication increase the life beyond this.
Vibration isolaters and flexible connection at inlet and outlet can be minimise transmission of vibration and noise to building structure and ducts. |
