SBCONBiflow SB Bifurcated Axial Fan Application
- Kitchens
- Spray Booths
- Hot Gas Situations
- Corrosive Atmospheres
- Boiler Houses
- Heavy Industrial
Construction
- The all metal fan casing provides a long lasting and robust construction.
- The units have been constructed from a single sheet of steel, axial impellers are mounted within the length of the unit casing; the motor is to be located in a tunnel which traverses the casing making the unit suitable for temperatures up to 200 ° C.
- All casing parts are heavy gauge mild steel sheet, roll formed and welded, then hot dipped galvanised to BS 729 after fabrication.
Fan/Impeller
- Adjustable pitch aerofoil impellers are provided with blades made from high quality pressure die cast aluminium (LM6), natural finish.
- Impellers are factory set at an angle to provide maximum performance.
- The hubs are manufactured from die cast aluminium alloy (LM24). Assembled impellers are to be dynamically balanced to Grade G6.3.
Motor
- Motors are to be foot mounted totally enclosed metric type to IP55, with sealed for life bearings, standard industrial paint finish and Class H insulation to EN 60034-5.
Features and benefits
- The Biflow SB is a quality range of bifurcated axial fans with a conical casing, specially developed for handling more hostile air movement applications.
- Biflow SB is designed so that air throughput totally by-passes the motor, keeping the motor out of the airstream in a cooler environment
