  • High Performance and Innovative Design
  • Adjustable air foil deflectors optimise air throw distance and direction
  • Transfer electrical energy into kinetic energy to form a focused airflow
  • Performance enhancing intake fibreglass cone
  • Balanced heavy duty corrosion resistant 6 paddle aluminium blades
  • 80,000 CFM at high speed including entrained air and 36 CFM/Watt
  • De-stratisfies air on low speed covering 15,000ft2 using only 300W of power
  • High speeds creates 1200FPM of velocity under the fan and 300 FPM at a distance of 75 feet on both discharge sides for a total of 5,250 feet of cooling area
  • Optional variable frequency drive allows you a smooth speed adjustment from 300RPM down to 50RPM – fan power consumption reduces with speed
  • Heavy galvanised motor mounts straightens the air as its propelled through the venture and throws the air efficiently over the air foil deflectors
  • Extremely quiet operation on all speeds

The ECVC Fan is the most efficient fan available that creates ECVAirTM (effective cooling velocity technology) at an amazing 112 CFM per watt. When running on high speed it creates a high speed wave of air directed over the cows and across the floor. Unlike traditional panel and basket fans, the ECVC Fan produces a cooling wave of fresh air that surrounds the cow reducing heat stress which increases laying time and keeps bedding dryer. Further reducing SCC, mastitis and insects. This longer lying time increases milk production and improves animal health and reproduction. 



  • Corrosion resistant fibreglass housing
  • Heavy duty pulley and bearing assembly
  • Maintenance free motor
  • Quick change belt
  • Can be mounted on steel post, building column or suspended from the ceiling
  • Optional variable frequency drive (VFD)
  • 6 directional airflow deflectors
  • Balanced heavy duty corrosion resistant 6 paddle aluminium blade
  • Chipped fully assembled, except for the air foil deflectors
  • Can reduce heating and cooling costs by up to 50%




In cattle barns:

  • Create extreme air velocity for cow cooling
  • Insect control
  • Dry out bedding
  • Air foil deflectors direct the air over and under the cows better than any other fan
  • One fan can replace up to 4 large single speed panel fans or basket fans with half the power
  • You can adjust the fan performance to meet your internal environmental requirements 365 days a year using the VFD
  • Re-circulates air throughout
  • Reduces humidity and recaptures trapped heat at the ceiling

In industry:

  • Air pattern covers 15,000ft2
  • Can be used for ceilings up to 40 feet
  • Can create an air curtain to keep cold air out in the winter and hot air out in summer
  • Slowly push air in a 360° radius


Technical Specification

  • 72” motor is 3HP or 2.2kW on high and 3kW on low 230/460 VAC. Amp 8.2/4.1
  • 50” motor is 1HP or 1050W on high and 300W on low
  • Optional variable frequency drive on 50”/72” fans
