A dual baffle system which can be incorporated into automatic air inlets used in livestock facilities. This system consists of four different components: two baffles, spring, opening mechanisms, and stationary bracket. This baffle system is positioned inside an automatic air inlet. The two baffles are hinged at the top and bottom of the inlet respectively and the opening between the baffles is allowed to increase or decrease. The opening mechanism is connected to the bottom baffle and allowed to slip through the stationary bracket. These two components allow the two baffles to open and close simultaneously. The spring allows the system to open and close to maintain the desired flow rate through the inlet.
