New energy-saving screw blowers for industry

New sizes in the Delta Hybrid line of screw blowers (photo) are designed with smart features that can realize energy savings as high as 30% compared to a conventional positive-displacement blower. Screw blowers are primarily designed for oil-free conveying of air and are suitable for many key industrial applications, from pneumatic conveying and homogenization to wastewater treatment. The blowers are equipped with an innovative compressor stage with new high-efficiency screw profiles and internal flow optimization. This is coupled with motors of energy-efficiency class IE4 as standard, optimized guiding of cooling and exhaust air, as well as a self-tensioning belt drive with an efficiency of over 98%. An effective sealing concept for the driving shaft and conveying chamber minimizes natural wear and also guarantees oil-free operation in accordance with ISO 8573-1 Class 0. The patented reactive silencer requires no absorption material and successfully prevents contamination of process air or of the downstream process system. This is a decisive factor for reliable operation in the food or wastewater-treatment sectors. Booth 843 — Aerzen USA Corp., Coatesville, Pa.
