designed for the US Navy for supplying fresh air to the holds and
other inaccessible areas of ships, their success
led to hundreds of industrial and commercial applications. Their
low output velocity and small
size made these units suitable for ventilating smaller
room areas in schools, hotels, etc. e Construction The low tip speed of the Multivane type wheel, with
forwardly-inclined blades, resulted
in quiet operation. e Performance Airflow
