While deciding on Mechanical ventilation systems and Fans in order to meet the ventilation and cooling needs in (animal) dairy and cattle farm buildings; Other factors such as (THI) Thermal Humidity Index, Farm System, Barn management, Footprint per stall , Animal traffic and flow , Manure management and usage , Fan maintenance, number of fans should be considered for ventilation.
Dairy Ventilation systems
Fans have the highest effect on operating costs which are part of the mechanical ventilation. Therefore the selection of the fan types and models are important among all ventilation systems. Dairy Ventilation systems for dairy and cattle housing is vital to fight heat stress and air quality for high yield animals
Fan types and applications
- Air flow direction: Vertical, ceiling, versatile.
- Purposes: Suction, Discharge, Exhaust Destratifiers.
- Speed controls: Gear box, inverter
- Motor types: Brushless, permanent magnet synchronous, Asynchronous
Axial Fans
There are square and ringed models: It is preferred to be used as an open tunnel in barns with grilled floors, in dry climate regions, in high-walled barns with low natural ventilation, in barns with tunnel type ventilation, material bedding (stalk-sand), in buildings with dry climate and low humidity . It maintains the air quality at an acceptable level in the area where the animals are located.
Square and Round fans
It provides sufficient air circulation inside the building while evacuating by pushing the rising hot air forward. Horizontal air blowers serve as suction and exhaust; It blows the rising hot air that it sucks from the back towards the front, allowing the hot air to escape.
- Engine positioned in the airflow for maximum impact.
- Static and dynamically balanced propeller.
- Cast aluminum impeller hub for optimum bearing protection.
- Belt driven propeller providing low noise levels.
- Exhaust and wide blowing possibility and area.
- Open Tunnel can be used for air pushing
- Mounting kits for ease of assembly.
- Horizontal support bar to reduce the pressure in the fan guard in ceiling.
- Tilting bracket for accurate and easy hanging angle adjustment
- .
- Horizontal support bar to reduce the pressure in the fan guard in ceiling.

Ceiling fans Vertical
In addition to being quieter and more economical than horizontal fans, it meets high efficiency expectations with efficiency, low power consumption and low maintenance costs. Due to the advantages it provides, its use has been more effective, beneficial and economical. It offers ideal solutions as a ventilation fan for industrial areas, warehouses and industrial facilities as well as for dairy and fattening barn.
In climates with high humidity and humidity, in barns where floor and air drying is important (soil / compost floors), for curtained or open-sided or semi-open barns with natural ventilation facilities By creating a high enough air velocity; It dries the ground and creates a cold wind effect on animals.

Geared fans VS / VSL
VS fans are preferred for use with animal cooling system THI. In addition to high m3 volume air Blows directly to the floor that increases the amount of air as unit. That collects the moisture in the environment which effects cool feeling.
Vertical fans (Helicopter) blow air directly over the animals and the ground, increasing the amount of air per m3 per unit area. In this way, while giving a feeling of coolness, it provides the collection of moisture in the environment.
- Exceptionally functional and economical Asynchronous gearmotor fan VS. As barn ventilation fan with axial reducer, gear motor, cost-effective, highly functional and ideal for heavy duty works.

Flexible fans
Special flexible structure allows it to operate horizontally, or to be tilted between 0 ° and 90 ° when necessary: The aim is to maximize the air flow even in the most complex situations. As a hybrid of horizontal and vertical fans for low buildings where other fans cannot be installed and in milking parlors, waiting areas where animals are concentrated in a limited area and heat stress reaches high levels.
VERTIGO fans
VERSATILE FANS can be positioned according to need by working both horizontally and vertically. VERTIGO shows its highest potential in milking and waiting areas.
The frame with position locking mechanism optimizes the desired air flow by rotating it horizontally or at required angles from 0 ° to 90 ° for barn ventilation fan. Safety net can be installed
FLEXIBLE FANS (moving) work both horizontally and vertically and are positioned according to need. It is generally suitable for milking areas, waiting areas and barns and shelters that need flexible use.

Ventilation Efficiency AMCA
When choosing barn fans for ventilation systems, it is important to check the ventilation efficiency rating (VER) of the fan listed as CFM * per watt (cubic feet per minute )
Humidity is important, not temperature!
Nearly all over the world, “Temperature-Humidity Index Program (SINEP)” has been prepared in order to predict the time periods in which temperature-humidity stress may occur, which causes significant yield losses in our country’s cattle breeding, thus ensuring that our farmers take the necessary precautions and minimize their losses.
Efficiency of ventilation standards AMCA
When choosing barn fans for ventilation systems, it is important to check the ventilation efficiency rating (VER) of the fan listed as CFM * per watt (cubic feet per minute ) . Untested fans can have a rating of 50% less than a manufacturer’s advertisement, so it’s important to find fans that have been independently tested.
