Vertical recirculation fan Zefir ![]()
Vertical air mixing
Zefir is a new effective way to optimize the microclimate in poultry- and livestock houses
Mixes the upper and lower layers of air, distributing it evenly throughout the building
On warm days...
Increases air velocity in the area occupied by the animals - giving a cooling effect during the hot periods
The best effect can be achieved when Zefir is used (at low speed) with high-pressure cooling together, because so cooled air is distributed more quickly and evenly throughout the building
On cold days...
The heated air from the heat generators is evenly distributed throughout the building, what ensures a uniform climate with an even distribution of the birds in the poultry house
Comfort for animals
The Zefir fan draws dry and warm air from the ceiling into the bird's area. It distributes the air stream at a fixed height above the animals, which feel it as a chill breeze, not like a draft as in tunnel ventilation
The air stream from Zefir pushes upwards the lighter gases that accumulate at the litter, reducing the concentration of CO2 and NH3 and dries the litter
Saving for the farmer
It allows delaying the transition to tunnel ventilation
Effectively reduces energy consumption for heating and cooling
By small animals the fresh air from outside is not necessary for minimum ventilation
Prevents from condensation in the building
Zefir assembly
The impact of the Zefirair stream is felt within a radius of 10m, so in buildings wider than 20m should be more equipment installed
The pulleys for suspension the Zefir to the ceiling – included
The Zefir can be controlled by some power regulator - for example SPA-12 regulator, to which 3 Zefirs can be connected
