Energy Efficiency

Recovers up to 75% of the energy from the extracted air and uses it to temper the incoming fresh air, optimizing the energy required to pre-cool or pre-heat the fresh outside air.

Balanced ventilation

ATMO appliances supply fresh, tempered air into indoor spaces while removing excess moisture, ensuring a healthy, comfortable living environment.

Easy Installation & Maintenance

ATMO appliances feature easy-connect ports and balancing taps to simplify installation and commissioning. Unobstructed front access allows for quick cleaning and easy maintenance.

ENERGY STAR® Certified

These appliances (except for ATMO 150H) have been designed to meet the latest and most stringent ENERGY STAR® requirements, making them even more dependable, efficient, and simple to install.

If using an ATMO150E or ATMO200E for a simplified installation, i.e. connecting the appliance’s supply air duct to a furnace's return air duct, the appliance must operate continuously. In case the appliance is turned off, the furnace will continue to draw in outdoor air directly into the furnace without re-heating or re-cooling. If the appliance is installed such that the homeowner may turn it off during the cold or hot seasons, we recommend installing a motorized damper ADC 6 between the appliance’s supply air and the furnace's return air duct that closes when the appliance is not operating.

Mounting brackets (#463942) are sold separately.
