Greenheck has redesigned its premium model SP bathroom exhaust fans. The fans are available in six sizes, SP-A50 through SP-A190, and have sound ratings as low as 0.3 sones, company officials said. Designed for ceiling-mounted exhaust applications, the fan has insulated housings and vibration isolators located between the motor and housing. The fan is licensed by the Air Movement and Control Association’s Seal for Sound and Air Performance, is UL-listed and meets Energy Star requirements for its increased airflow and decreased power consumption and sounds, officials said. The fan is ideal for multifamily housing, hotels, hospitals, schools, bathrooms and storage rooms, and can be used with Greenheck’s electrical accessories, control options and its herringbone or Tuscan grille patterns are available in white or oil-rubbed bronze.
