Ventilating your crawlspace helps control moisture that can lead to mold, fungus, damp rot and poor air quality.
Automatic air vents open and close without electrical use. They start to open when temperature reaches 70°F providing fresh intake of air. Vents close around 40°F to help protect pipes and save on utilities. Automatic Air vents are easy to install and come with mounting hardware. No mortar is need for installing.
We only offer Temp Vent and Solar Tek RAM series automatic vents. We feel they are the higher quality and come with a warranty.
Spray the bi-metal coil every few months with lubricant they will better and longer.
