JumboFan Huge Ceiling fan HVLS for stables and barns

Altra-Air HVLS fans blanket a very large area with constantly moving air to create an expansive comfort zone. As a result, the big ceiling fan can create an evaporative cooling effect of three to four degrees Celsius throughout the facility.

During the heating season, the Altra-Air HVLS fan technology can de-stratify uneven temperatures that can be in excess of fifteen degrees Celsius from ceiling to floor. This results in significant energy savings since the heating system cycles less frequently.

The Tubercle Advantage

Tubercle Technology™ blades outperform all conventional airfoils. They accomplish this by:• Offering stall angles as high as 22°. • Always stalling gradually.• Eliminating span-wise pumping; the primary cause of efficiency loss in all rotating systems.• Eliminating tip stalling; the primary cause of blade noise and damaging vibration.• Lowering noise by offering Tubercle Technology’s™ hyper-stability which also lowers vibrations which cause wear and tear on the blades and drive train.

• Quiet, efficient operation, no annoying high speed circulating or exhaust fans.• Virtually maintenance free (recommended inspection every 20,000 hours)• Inexpensive to operate. Costs approximately 6 cents per hour for one fan at 0.75 kW (1 HP).• Greatly reduce the “recovery” time when overhead doors are open with a constant flow of air throughout the space.• Provide a constant even temperature from floor to ceiling and wall to wall.• Will minimize the need for expensive duct work in new construction for both heating and air conditioning systems.• A comfortable workplace environment increases productivity and decreases absenteeism.

Benefits of Altra-Air HVLS Fans

• Fans range from 2.4 to 7.3 m (8 ft to 24 ft) in diameter.
• Capable of moving nearly 188,000 l/s (397,701 CFM).
• Operates on 0.75 to 1.5 kw (1 HP to 2 HP).
• Variable frequency drive provides soft start and full variable speed operation.
• Creates a non-disruptive airflow.
• The largest 7.3 m (24 ft) Altra-Air fan consumes less power than the average hairdryer.

Technical Specifications

Altra-Air fans come with a lifetime warranty on the blades and hub. The motor, gear reducer and VFD control panel come with a three year limited warranty

Warranty

Envira-North's blade toppers prevent a rotor from falling or a blade from coming off even in the unlikely event of a catastrophic failure of the hub or drive system. The collet-type friction drive bushing connecting the hub to the reducer shaft allows controlled slippage in the event of a seizure of the reducer mechanism, or a failure of the soft start feature in the control panel.

Safety

Warranty is given the first year all assemblies. In accordance with the Warranty Certificate and the engine only the years of the warranty (depending on the warranty certificate given by Amperel Group).
