Fresh air intake system from Tjernlund Products
Tjernlund Products’ Fresh-Air In-Forcer will supply fresh outside air to dilute trapped pollutants and replace air vented by exhaust fans and fuel-burning equipment. The system can be installed through a 4” round exterior wall opening. Operating control options include manual operation by plugging into 115 VAC switched outlet, while the high-efficiency 90 CFM fan consumes 18 watts.
