Series 56 Special Duty Direct Drive Vaneaxial Fans are available in sizes 14 to 48" with air deliveries from 2,580 to 57,200 CFM. They are designed to be used from 4 to 14" static pressure. VB blowers were developed to meet the demand for equipment handling low-volume, high-pressure requirements. Standard sizes are 14 through 48".
Series 56 Fans feature Hartzell’s VB wheel, which was developed to meet the demand for low-volume, high-pressure requirements. A low pitch and a higher hub-to-diameter ratio make this impeller more effective than the VA models at high pressures while moving a relatively smaller volume of air.
The wheels are cast-aluminum, machined and hand-ground. They are dynamically balanced to ensure vibration-free operation at high tip speeds.
Additional Series 56 features:
- Solid-cast, aluminum impeller
- Industrial-grade, powder coat, enamel coating standard
- Dynamically balanced at the factory prior to shipping
- Supplied packaged, assembled and ready to install
