Below is a list of Direct Drive Blowers manufacturers from Zelienople, Pennsylvania. Direct drive blowers are air blowers that are used to generate airflow without the use of intermediate mechanical components. All direct drive mechanisms function by transferring energy directly from a motor to the intended moving parts. The advantage of direct drive over other systems (like motors that involve gearboxes) is increased efficiency (no energy is wasted in friction between superfluous gears or other parts), reduced noise, longer lifetime (because there are fewer moving parts that can fail after extended use) and precise movement.
