Cumberland’s Attic Vent System is precision engineered to extract solar heat from the attic space so it can be used as a valuable heat source. This unique and innovative design is cost effective, durable and easy to install.
Operation: Vents are operated with a linear actuator or curtain machine and are controlled by your ventilation controller.
Unique Door Design - exceptional air mixing due to the curved door profile which provides proper air velocity directing warm air from the attic into the house.
House Conditions: Significant benefits to Cumberland’s Attic Vents are drier litter and lower ammonia concentration levels, thus providing a better in house environment for the bird.
Fuel Savings: Mixing warm air from the attic with house air during minimum ventilation reduces fuel consumption as compared to using cold air through sidewall inlets. Fuel savings can vary depending on management, house construction and climate.
Retrofit Friendly: The Attic Vent System is designed to be retrofit friendly in most drop ceiling poultry houses.
Curved Door Profile: Curved door design directs air along the ceiling toward the house walls for gentle air mixing without downdrafts on the birds.
