The new Universal High-ESP Air Handler has been designed for use in high static pressure applications such as a manufactured or mobile home, or in a system that has restrictions in the ductwork which would place a strain on a conventional air handler not rated for high external static pressure. This air handler is equipped with a powerful and efficient DC fan motor that includes a fan with blades that are designed for quiet operation while still providing dynamic performance.

The unit is capable of reaching a maximum static pressure of 250Pa. It offers multiple installation positions (vertical, horizontal left, or horizontal right) for an easy fit into many applications. The Universal High-ESP Air Handler also uses a durable metal filter that is both easy to clean and corrosion resistant to ensure it has a long service life.
