ASHRAE 62.2

• 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 500000+ 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 100000 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

The FAV (fresh air system) from field controls is an intelligent, automatic, year round ventilation system that integrates with an existing HVAC system and thermostat to meet ASHRAE 62.2 requirements. The FAV includes proven components for simple, reliable, fresh air delivery for improved indoor air quality. The FAVC (fresh air ventilation control) utilizes the central fan to supply outdoor air from a known source through a controlled duct for fresh air intake, while the FAD (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.
