Here's a better way to ventilate bathrooms

Discover how VentZone can save installers on installation, time, and materials while giving homeowners effective bathroom and whole-house ventilation

American Aldes VentZone® IAQ systems are the only central ventilation systems available that provide precisely regulated whole-house Indoor Air Quality and centralized bathroom fans in a single, highly effective and efficient ventilation kit. Each kit has the capability to provide low continous IAQ ventilation and zone-based on-demand "boost" ventilation.

  • Install bathroom exhaust ventilation in all the bathrooms using fewer materials than with traditional bathroom fans
  • Only one exterior vent or roof cap is need rather than one for each bathroom, so installation is quicker
  • Fewer outside penetrations means there's less chance of rain, bugs, or other problems  

Why builders and installers choose VentZone® 

  • Continuous low-volume fresh air circulating throughout your home, clearing pet odors, toxins from cleaning supplies, stale air, and cooking odors
  • Boost ventilation in each bathroom quickly clears odors and humidity from the bathrooms when needed
  • Protects one of your biggest investments, your home, from mold and mildew
  • The ventilator (fan) itself is located away from the bathrooms, usually in an attic near the outside wall, so there's no noise at the grille

Why homeowners choose VentZone®

How it works: The patented Zone Register Terminals ® (ZRTs) replace traditional bathroom fans or static grilles. When the ZRT damper is closed, it provides low-level continuous whole-house ventilation through a constant airflow regulator. When boost airflow is needed (when the homeowner turns the fan on in the bathroom), the ZRT damper opens and air is exhausted. When the boost is no longer needed, the ZRT closes and the airflow returns to low-level continuous ventilation. 


The system provides boost ventilation to the bathrooms in use, whether that means just one bathroom or multiple bathrooms at at time. All ZRTs are ducted to a central Aldes ENERGY STAR certified multi-port ventilator, so there's no fan noise at the grille, and only one outside penetration is needed, as opposed to traditional bathroom fans that typically require an outside penetration for each bathroom. 

Pro: Ability to ventilate each bathroom as needed


Con: Purchasing, installing, and ducting a fan for each bathroom is expensive and time-consuming

Traditional Bathroom Fans vs. Centralized Ventilation

Pro: No need to purchase, install and duct a fan for each bathroom


Con: Boosts all fans at once, even when boost is only needed in one bathroom

With VentZone®, you get the PROS of both without the CONS

Pro: Ability to ventilate each bathroom as needed


Pro: No need to purchase, install and duct a fan for each bathroom


PLUS: Low-level continuous ventilation for whole-house IAQ
