NEWS RELEASE          April 2013

Using GC1140 Gravity Vent with Machine Actuator
to Prevent Air Leakage in Attic

When fresh air is needed in the poultry house, the vent machine will release tension from ceiling air vent. Once a static pressure of 0.06 is achieved, the ceiling inlets will open, bringing fresh air into the room. When fans shut off, the attic inlets will immediately close. The vent machine will then pull tension against the attic inlet, ensuring a tight seal and eliminating hot air from entering the attic. Learn more
