NYB Single-Width Fans feature three types of backward inclined wheels for maximum selection flexibility and optimum performance: AcoustaFoil® wheels with airfoil blades for highest efficiency in clean, dry airstreams, PLR wheels with flat, single-thickness blades for best performance in moist or mildly contaminated airstreams, and BC wheels with curved, single-thickness blades for good performance in moist airstreams. Call today for details on our SWSI Backward Inclined Single Width Fans Type 1-3.
The New York Blower Company certifies the Class 3 Backward inclined Single Width Fans are licensed to bear the AMCA Seal. The ratings shown are based on tests and procedures performed in accordance with AMCA Publication 211 and comply with the requirements of the AMCA Certified Ratings Program.
|Wheel Design:||Backward Inclined-Airfoil
Backward Inclined-Curved Blade
Backward Inclined-Single Thickness
Backward Inclined- Airfoil: Aerodynamic airfoil-blade is the most efficient design with the lowest sound levels for clean air applications.
Backward Inclined- Curved Blade: Curved, single-thickness blade is ideal for high volume, low pressure applications.
Backward Inclined – Single Thickness: Flat, single-thickness blade surface best suited for airstreams with light material.
