Fresh Air Ventilation Systems (FAV)

Our Fresh Air Ventilation System (FAV) features a Fresh Air Damper (FAD) that works automatically with the Fresh Air Ventilation Control (FAVC) to efficiently and effectively distribute air throughout the house.

The FAVC utilizes the central fan to supply outdoor air from a known source through a controlled duct for fresh air intake, while the Fresh Air Damper prevents infiltration during off periods. When there is a call for fresh air intake, the control opens the damper allowing fresh air to enter the HVAC return. When the control is satisfied, the damper is closed.

The damper uses a quiet, neoprene no-leak seal so unwanted air and humidity are controlled. The seal is tested 500,000+ cycles and meets flammability FMVSS-302 requirements. Power Open, Power Close The power open/power close damper means the motor uses very little power unlike competitive dampers that use a spring close/ power open motor which stay fully powered during the open cycle an waste energy. Most reliable damper on the market rated over 100,000 cycles.

Our FAV Systems are a type of Central Fan Integrated (CFI) Ventilation. CFI Ventilation is better than Exhaust Ventilation like a bathroom fan and more economical than a Balanced Ventilation system like an HRV or ERV system. The Exhaust Ventilations systems are easy to install, have low energy use, but they draw in air from uncontrolled sources and can create negative pressure. HRVs or ERVs capture a nominal amount of energy in the exhaust air, which helps on energy cost, but they are expensive to install and maintain.

Plus, CFI systems are more effective than a bath fan. Bath fans can quickly create negative pressure in the bathroom and ultimately become ineffective, not exhausting the air. The replacement air with a bath fan typically enters from poor air quality sources such as the garage, attic, or basement where automobile fumes, radon gas, and other household chemicals may enter.

Meets or exceeds ventilation standard ASHRAE 62.2.
