Ventilators - ETAvent technology has proven itself well over the last years!
The energy saving effect is significant and the reliability has been proven. The advantage of frequency-dependent regulation lies in the significantly lower stress on the wrapped insulation of motors. With the alternative, energy-efficient frequency conversion, a high amount of filtering and throttle wiring is required in order to prevent damage to the ventilators. In many cases this wiring is not properly installed and this shortens the life of the ventilators. For these reasons we primarily utitlize the more reliable ETAvent technology. However, in some cases the required ventilators are not available in ETAvent technology. In these cases, we use it with a proper filter frequency regulator with a proper filter circuit..
The standard (Asyncron and ETAvent) series ventilators are also manufactured and used as duct fans. For tube ventilators in our exhaust stacks sturdy PVC sleeves are first pressed in to stiffen the stacks. This has the great advantage that it allows us to ensure a uniform air gap between the blade and stack wall, which reduces the pressure loss. With many other suppliers this is not taken into consideration and there is significant pressure loss because the air gap is too large and often uneven..
