Best Greenhouse Ventilation Equipment Buying Guide
Before choosing the best greenhouse ventilation equipment you should consider following options:
1. Heat-reducing ventilation fans: You can get ventilation fans that reduce heat as well as air. This is because of the energy-efficient motors they have.
The heat they generate is minimal. It is just enough to move the air around the greenhouse.
You can get the fans in different sizes depending on the size of your greenhouse. The most common ones are the axial and centrifugal fans.
The most efficient ones are the centrifugal fans. For a medium-sized greenhouse, you can get the ones with diameters of 48 inches to 60 inches.
2. Water-powered ventilation fans: These are also known as self-generated fans. The water-powered fans use the energy from the wind to rotate a turbine.
The energy generated from the turbine is used to power the fan. This makes it very efficient and reduces the electricity bill.
You can get ventilation fans with different power levels. The most common ones are the ones that generate 50 watts to 500 watts of energy.
However, it is important to get a fan that has a higher power rating than the size of your greenhouse. This is because the wind intensity in greenhouses is low.
