Essential Info

Your clothes dryer is connected to a 4" diameter exhaust duct that is open to the outdoors. In the winter, cold air can enter the duct and flow through your dryer and into your house, while your heated air just pours right out! Many common discharge vents use a sheet metal flapper in an attempt to reduce air leakage. However, this primitive technology usually does not provide a positive seal to stop the air leakage. Over time, lint clogs the flapper valve causing it to stay open - this is like leaving a window open with the heater or air conditioner running.

The Battic Door Dryer Vent Seal reduces unwanted air infiltration. The vent remain closed unless the dryer is in use. When the dryer is in use, the heated dryer air will push up the floating shuttle, allowing the air to escape from the bottom of the vent. Once the dryer stops, the shuttle drops back down, keeping wind, birds, bugs and rodents outside. Also great for bathroom and kitchen exhaust fans!

This vent seal is made of high impact ABS plastic, able to withstand temperatures from -148 degrees Fahrenheit to 230 degrees Fahrenheit. It will mount easily on siding, brick, or cement. The top may be removed for cleaning. The vent can be painted if desired.
