air circulation fan destratification v flo

It's not only people that appreciate the movement of air. Many plants, livestock and processes also rely on air movement. Whist we may appreciate the economic sense in destratifying air to lower heating bills, we may not realise that traditional destratification fans are not always the best way to move air uniformally about in a room. Air circulation fans which are used for generally moving air around in a space come in many guises and we have covered basket fans and oscillating wall mounted fans in previous blogs. In this blog we will look at air circulation fans of a type otherwise known as V Flo fans and their ideal application in green houses, poultry sheds and drying processes.

Introducing V Flo Air Circulation Fans

There are plenty of air circulation fans available, some fixed and some that oscillate, however there is only one fan that is fixed and designed specifically for large open buildings with relatively low roofs and that is the V Flo. Although it is a normal axial fan pulling air vertically upwards, what makes this air circulation fan unique is the shallow conical defector. The effect of this is to turn the discharged air and to spread it out horizontally so that a coander air flow pattern is established in the building. Like all fans their effectiveness depends upon their size and airflow and they can only be effective over a limited area. For larger buildings several V Flo air circulation fans may need to be used.

The Advantages of V Flo Air Circulation Fans

The principle advantage that comes with V Flo air circulation fans is increased productivity because uniform air movement within a building ensures that there is an air current, even in the corners and at floor level, that prevents damp static air pockets that can harbour disease, and prevent drying.

  • Prevention of static air pockets that could harbour lingering dampness around plant foliage
  • Dramatically lowered plant losses due to rot and disease
  • Movement of foliage thought to toughen young plants
  • Lowered heating energy costs
  • Even movement of fresh air through the building ensuring no pockets of hot air
  • Minimization of stock loses due to foot and leg problems casued by damp air pockets and damp litter
  • Control of humidity at the litter level
  • Increased comfort for the birds
  • Even air movement ensures even drying of product
  • Reduced drying times enabling higher product throughput and productivity
  • Elimination of high humidity static air pockets.
  • Lowered energy costs

Air is moved in a coanda air flow pattern bringing air vertically up into the fan where it is then thrown horizontally outwards. Air on the underside of the roof is also moved within this pattern by the friction of the air from the fan pulling the air above along with it.

Used V-Flo fans

One of our customers for V-Flo fans has changed thier business direction and as a result has around 20 used V-Flo fans for sale. They are only about 18 months old, some have been used in this time and some are still boxed as yet unused. If you would like any of these fans please contact us to enquire about availability and pricing.
