Energy-conserving homebuilding materials and 
techniques minimize fresh air intake...a major 
cause of illness, discomfort and structural damage.
The IN-FORCER mechanically draws outside 
air indoors to dilute pollutants and replace stale 
air without sacrificing energy savings.
The FAI4 Powered Air Intake provides a simple and economical way to provide fresh, outside air to dilute trapped pollutants and replace air vented by exhaust fans and fuel burning equipment. Plug into a switched outlet, use a remote on/off switch or a plug-in timer to operate on a desired schedule. Standard 4” flex or metal duct may be used for ducting. The efficient 75 CFM fan consumes only 18 watts.

  Reduces negative pressure a major cause of flue gas spillage and radon gas entry. Reduces moisture, mold mildew buildup.
