The staged air volume (SAV) system utilizes a variable-frequency drive to automatically adjust the indoor fan motor in sequence with a rooftop unit's heating, cooling and ventilation operation. The VFD also ensures a slow ramp-up to help control air volume surges and reduce noise in duct systems during fan speed changes. Available on all Weather Series rooftops and Gemini air handlers in the 7.5-ton size and larger.
