Sun-North Altra-Air Sailfin HVLS Fans

Livestock adapts well to relatively consistent cold or hot conditions. Production is affected when there is a repetition of abrupt temperature swings. Properly designed ventilation will moderate or eliminate the abrupt temperature swings offering the animal the sensation of cooling under hot conditions and warming under cold conditions.

One of the great recent innovations in livestock ventilation is the very large (up to 24 FT diameter) HVLS ceiling fans.

Sun-North’s sister company, Envira-North Systems manufactures the Altra-Air Sailfin series of ceiling fans.
