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.
|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.
