There has been an increasing requirement for backward curve impellers in many applications such as telecommunication equipment, computers, medical devices, heating and air conditioning, refrigeration, heat exchangers, power supplies and others with high packing density that creates a high system pressure restricting air flow.
Unlike many other centrifugal types of air movers Diplomat blowers do not require a scroll housing to obtain high static pressure. They are available with a variety of options including tachometer, fan performance sensors, and speed control.
