What is the value of using a power vent machine as part of a ventilation system?
The “power vent machine” or static-pressure inlet controller is one of the most important technological advances in poultry ventilation in recent years. It combines a static pressure sensor and inlet actuators to give you automatic adjustment of your sidewall or ceiling air inlets during cool-weather or transitional ventilation. With a power vent machine, you don’t have to manually adjust inlets every time conditions change and fans kick on or drop off. A good power vent machine continually adjusts inlets to provide the precise amount of inlet opening needed to shoot air into the house fast enough and high enough to get good mixing and avoid chilling birds. It’s important to realize that the power vent machine is actually controlling the house static pressure. To get good airflow through our vent boxes, we need a static pressure of about 0.08 to 0.10 inches (20-25 Pa). The vent machine senses whatever the static pressure is, and either opens up or squeezes down the inlet openings to ge
