Belt drive exhaust fans for livestock barns/greenhouse/
1. Automatically operate. Take advantage of energy from nature,
exhausting turbid, humid hot air to exterior and supplying fresh
air to interior. Produce air convection as a heat radiator,
reducing indoor temperature, increasing air fresh. Reduce air
conditioning load, increasing the cooling effect.
2. No operating cost, no electricity consumption, environmental
3. No maintainance needed, life-long service
4. Light weight, strong and durable construction
5. Weather resistance, strong fray resistance, fine non-viscidity,
self-cleanness, high revolving sensitivity and high air venting
6. Easy installation. Installation Position: Flat roof, pitched
roof, concrete roof and contour plate of various industrial plants.
1. corrosion resistent
2. high efficiency
3. requires absolutely no electricity
4. withstand severe rain and wind
The roof ventilation fan applies the theory of convection between
natural wind and air to accelerate and transform any parallel
airflow into vertical so as to improve the indoor ventilation. The
hot air rises and cold air falls, which makes the fan rotate. So
the indoor heat, stink and dust are exhausted effectively. It also
can effectively remove indoor soot, smoke, odor, moisture, heat,
decorative harmful gas, dust, human matabolism and other dirty
volatile mixed-doped odor as well as virused and bacteria invasion.
As a result, it improves the working environment, protects workers'
health and enhances the working efficiency.
Move and refresh the stagnant air in your barn or building to
create a healthier and more productive agricultural environment.
These exhaust fans are great for reducing dairy cow and poultry
heat stress. Our exhaust fans provide excellent ventilation for
poultry laying cages. Refresh your barn's air supply while removing
respired moisture to provide a dry and draft-free environment for
horses. Create a cooler more comfortable growing environment, which
can directly contribute to productivity, quality and profitability
for your greenhouse business. Exhaust fans also works great in work
shops and buildings.
