With an output of up to 77,000 m³/h the Alpha Blower is Aerzener Maschinenfabrik's most powerful product. The rotary blower represents performance, reliability and efficiency to an equal degree. "In view of rising energy costs, our customers are increasingly looking at the total cost of a machine over its entire productive life. In very energy-intensive applications our products sometimes pay for themselves in less than a year", explains Mike Hühnerbein, strategic purchaser at Aerzener Maschinenfabrik. In order for the Alpha Blower to be able to deliver its performance in continuous operation for many years, the continuous lubrication of its moving parts is essential. The oil supply is provided by power units from HANSA‑FLEX subsidiary Willmann Steuerungstechnik GmbH. They ensure that the right amount of oil is always in the right place at the right time. The design and construction of the individually manufactured power units was carried out in close cooperation with the customer. "With 24/7 operation our customers expect the highest standards from our machines. We are delighted that Willmann, just like us, attaches the greatest importance to quality and reliability." For Hühnerbein, this includes not only manufacturing and documentation, but also consideration of a wide range of environmental conditions.
