    Lamson and Hoffman Variable Frequency Drives

    Hoffman and Lamson blowers with VFD's have been successfully used in wastewater treatment applications for years to control the airflow more efficiently than inlet valve throttling. For wastewater treatment plants, blowers are a major source of power consumption. As the cost of energy has increased, the cost of VFD technology has decreased resulting in a faster payback for the capital cost of a VFD blower.  Gardner Denver can help develop an appropriate selection and control scheme to help you realize these savings.
