This blower is now even more energy efficient

The E-Blower extends the high-efficiency solution provided by the company’s Delta Hybrid series in the low volume flow range. The new E-Design delivers a reduction of power demand of up to 4%, depending on volume flow and pressure difference, says the company. The savings are due, in part, to flow-optimized guidance of the intake air in the acoustic hood and in the filter silencer. A patented inlet cone (also used with Delta Hybrid rotary lobe compressors) not only minimizes the pressure loss, but also the noise emission. Additional savings are due to an electric motor-driven cooling fan, which replaces the shaft-driven acoustic hood-cooling fan. Six different sizes are available, with intake volume flows from approximately 30 up to 1,000 m³/h, and overpressures up to 1,000 bars or negative pressures up to 500 mbar. — Aerzener Maschinenfabrik GmbH, Aerzen, Germany
