Today's air-tight homes make proper ventilation more essential than ever. You can now improve the quality of your indoor air by installing the Aprilaire 8126A Fresh Air Control System. By measuring the outdoor temperatures and humidity, this unit will determine when it is appropriate to bring in the right amount of fresh air from outside. The fresh air is introduced into the home duct system, heated or cooled by your furnace or air conditioner, and circulated throughout the home. This unit will not pull fresh air if the outdoor conditions are too hot, too cold or too humid. Every home should have a fresh air system, and the Aprilaire 8126A is an excellently designed and low cost way to do so.


Your order will also include Alpine's exclusive installation video on DVD! Watch as a pro tackles the project from start to finish. You'll have all your questions answered as you see how easy it is to install yourself.

Also available is Alpine's Fresh Air System Installation kit (AHA091). This kit contains all the extra supplies and materials needed to install the Aprilaire 8126A system. No need to run out to the hardware store, as everything you need is in the kit.

Includes the following items:

  • Aprilaire digital ventilation controller
  • Aprilaire normally closed damper
  • Aprilaire 24VAC transformer
  • Outdoor temperature sensor
  • Alpine's Exclusive Installation Video on DVD
