Box Ventilators 

EXHAUSTO Box Ventilators BESF and BESB are used in extraction or supply air ventilation systems where demands for efficiency and reliability combine with low operating cost and long operating life-time.

Regular cleaning and service is essential to ensure operation at full capacity. The Box Ventilators have a hinged service door where the motor and centrifugal impeller are fitted to facilitate access for cleaning and service procedures.

BESF Box Ventilator is constructed with a galvanised sheet metal and insulated fan housing with a centrifugal forward-curved impeller.

The fan housing and cabinet of the BESB are made of hot-galvanised sheet metal, and the centrifugal impeller is made of cast aluminium. The impeller (B-wheel) has backward-curved blades to ensure efficient transfer of energy from the motor to the air.

The BESB is featured on the Danish electricity companies' list of economical fans - i.e. fans that meet requirements for superior energy efficiency.

All sizes of the BESB can be supplied in special split versions for installations with narrow access routes. The BESB Split is supplied fully assembled, but can be dismantled for internal transport and then re-assembled at the installation site.
