3. Energy Transfer Core
As the exhaust and fresh air pass through opposite sides of the Energy Transfer
Core heat is transferred from the warm side to the cold side. This heat transfer
reduces the cost of conditioning the fresh outside air that is brought into your
home. In addition, moisture is transferred from the wet side to the dryer side.
This moisture transfer reduces the drying of the air inside your home that occurs
during the winter months and reduces the amount of moisture that is brought into
your home during the summer months. The core removes easily for cleaning.
4. Controls - Speed Control
Easy operation, simply rotate the Perfect Window™ ventilator fan speed control
to your desired setting.
