AprilAire Model 8100 Energy Recovery Ventilation System (ERV)

The whole-home AprilAire Model 8100 Energy Recovery Ventilation System (ERV) is among the most energy-efficient methods of exchanging the air inside your home with fresh outdoor air.

Today’s homes are being built tighter for energy efficiency. Unfortunately, this also makes it nearly impossible for your home to expel stale, indoor air and replace it with fresh, cleaner outdoor air. As a result, unpleasant odors and harmful pollutants become trapped in your home.

AprilAire Model 8100 Energy Recovery Ventilation System manufactured in February 2012 or later may be controlled with the model 8910 Aprilaire Home Comfort Control, Model 8620 Thermostat, or by the Model 8120 AprilAire Ventilation Control System, allowing ventilation to occur on a schedule.

About the AprilAire 8100 ERV EnergyMax® Transfer Core

The heart of the ERV is the EnergyMax® Transfer Core, which uses enthalpic technology based on the second law of thermodynamics to enable the transfer of heat as well as moisture into and out of your home.

This means:

  • In the summer, the ERV uses the stale, conditioned indoor air you’re expelling to cool the incoming hot air.
  • In the winter, the ERV uses the stale, heated indoor air you’re expelling to preheat the incoming cold air.

Removes Pollutants

AprilAire whole-house ventilation removes particles common in most homes to reduce mold, bacteria, pollen, harmful chemicals, and other VOCs.

You can save energy through the use of AprilAire thermostat’s convenient set-back programming.
