The Aprilaire 4021 orifices is the tiny nylon components which accurately meter the flow of water into your humidifier and are for use with Aprilaire models 112 and 224. They allow a specific amount of water to go into the humidifier, some of which is evaporated and some which performs the important flushing action. This keeps the Water Panel clean and reduces maintenance to a minimal amount.
