Description
The Lennox 25W70 Exhaust Screen is a robust part that is used to shield the gas furnace of high efficiency from various hindrances such as debris, pests, and weather conditions. This is installed on the exhaust vent of compatible HVAC systems to allow air to flow freely while excluding debris from getting inside and causing harm. The Exhaust Screen also ensures adequate venting to improve the efficiency of the system and reduce the chances of low performance or short durability of the furnace. Also, it plays an essential role of filtering out contaminants from the indoor air from getting into the system.
