KFB

Centrifugal fans for building ventilation and aeration

Especially developed for the tough operating conditions of a kitchen extract air fan. The impellers used with backward curved blades are insensitive to fatty deposits. They are also more efficient, which means the operating costs and the investment costs for the transformer control unit are much lower.

  • 5 sizes
