![]() ![]() Still air incubators often take a little fine tuning. Humidity levels are also harder to control in still air incubators. Still air incubators will be warmer near the top and cooler near the floor since there is no fan to circulate the air throughout the incubator.īecause of these temperature differences, still air incubators are often operated at a higher incubation temperature compared to forced draft incubators. ![]() This draws fresh air in at the ventilation holes near the bottom of the incubator. Warm humid air is pushed out the ventilation holes at the top of the incubator. These styles of incubators rely on gravity and the natural way that dense, cool air sinks. Still air incubators are also referred to as gravity flow incubators, gravity ventilated incubators, or natural draft incubators. Still air incubators are usually small models since the still air ventilation system works better in a more confined environment. However, forced draft incubators also have a fan that aids with circulating air throughout the incubator. Proper air flow in the incubator is essential for removing old, stale air and introducing fresh air into the incubator.Īll incubators have ventilation holes, which allows air within the incubator to be exchanged with air outside the incubator. Developing embryos use up oxygen and release carbon dioxide as they grow. The difference between these two incubator types is the way that air is moved throughout the incubator. The two main types of incubators are forced draft incubators and still air incubators. What are Forced Draft & Still Air Incubators? ![]()
