Application for variable VAV terminal fans

VAV systems were developed in response to the early 1970's energy crisis. These systems reduced energy usage, sometimes at the expense of comfort. But today's building owners want the VAV system's economy without sacrificing comfort.

Many applications require a VAV terminal fan to achieve satisfactory comfort. Recent advances in air moving motor technology allow efficient variable speed operation of these fans.

Variable speed fans may be applied to improve comfort and save energy.
