The E-Blower extends the high-efficiency solution provided by the Delta Hybrid series in the low volume flow range. This new design among the positive displacement blowers offers a reduction in power demand of up to 4%, depending on volume flow and pressure difference. This improvement is the result of many a design optimization, including flow-optimized guidance of the intake air in the acoustic hood and in the filter silencer. Particularly worth mentioning is the patented inlet cone (also used with the rotary lobe compressor series) that minimizes not only pressure loss but also noise emission. Essential for the high energy efficiency of the blower is a revised cooling concept. An electric-motor-driven cooling fan replaces the shaft-driven acoustic hood cooling fan. Ideally positioned, it provides perfect ventilation under the acoustic hood – with minimum power requirement. In addition, the air is taken in at the cold side (front side) of the packaged unit and not at the warm side (back side) where the piping is connected and the waste heat discharges from the acoustic hood. The cooler the intake air, the more efficient the blower. For example, a 5 °C cooler inlet equates to 1% energy saving.
