Ceiling - Recirculation Fan Ventilation |
One of the great recent innovations in ventilation is the very large up to 7.5 meter (24 foot diameter) HVLS ceiling fan.
Sun-North’s sister company, Envira-North Systems manufactures the Altra-Air series of ceiling fans. Envira-North is the only manufacturer of this type of fan in Canada and the only manufacturer in the world using WhalePower Technology.
This technology means the 7.5m (24 ft) Altra-Air fan moves 395,000 cfm over 60 to 70 ft area, which is much cheaper and much more energy efficient then multiple box fans as seen in many facilities hanging from posts and ceilings.
The Altra-Air fan slowly moves and mixes massive amounts of air creating a more homogenous ambient climate for all forms of livestock. The horses sense an overall breeze, not an evasive direct blast of air. These very large Altra-Air fans draw the warmer air from the upper ceiling areas mixing it with the lower regions of air moderating temperatures.
Absolute Air |
With some horse facilities, alleyways and resting areas are restrictive and the Absolute Air equipment can solve the ventilation needs of these conditions.
Absolute Air is belt driven and of fibreglass and aluminum construction. Absolute Air has high and low speed selectors and is able to move 80,000 cfm over an area of 600 sq. meters. It is complete with 6 adjustable air flow deflectors.
