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. |
