CENTRIFUGAL FANS OF BS SERIES
(Backward straight blades /backward inclined blades)
BS centrifugal fans are designed for high performance industrial applications in air and gas transport, clean or dusty. Examples are industrial ventilation, fumes & gas extraction, combustion air delivery in burners, bulk materials pneumatic conveying, air cleaning through bag & cartridge filters, bulk products recover with cyclone separation, and many more. Fan's blades geometry is straight, in order to avoid particle stuck on them, and consequently loss of impeller's balance. Blades are also backward fixed according to impeller's rotation, to ensure high
performance at low energy consumption. All fans are tested in our own laboratory and come with their characteristic operation curve. Laboratory performance test is implemented according to ISO 5801:2017 standard. Besides standard series, special dimensions are also available to conform specific applications of pressure vs volumetric flow rate. Operating range of BS series fans is between 40 to 550mmWG static pressures (400 to 5.500 Pa) and 100 to 120,000 m³ / h volumetric flow rate. BS fans construction complies international standards of quality and safe operation. External casing is made of welded carbon, galvanized or stainless steel. Impeller's body and blades are made of steel. Special alloys can also be used for specific applications in chemical & food industry. Impeller is dynamically balanced to achieve vibration reduction
and long operating life. BS series fans are manufactured in two different types:
-N- (Normal) for operation with low power motors
-H- (Heavy) for higher absorbed power.
BS series fans can be constructed at standard couplings with electrical motor, to conform many applications (F1- F7 single air inlet, F4D - F6D double air inlet).
