Whisper Series
Sound-attenuated rotary phase converters for noise-sensitive environments. Under 60dB at 1 meter.
Overview
The Whisper Series uses an acoustically-isolated enclosure and vibration-dampened motor mounts to reduce operating noise to under 60dB — roughly the level of a normal conversation. Ideal for offices adjacent to machine areas, medical facilities, or any environment where converter hum is unacceptable.
Internally identical to the NL or NLT series for a given HP rating. All Whisper units include the same voltage balance, starting capacity, and continuous duty rating as standard Phoenix converters.
