  • AERZEN captures Thailand’s milling industry

    Siam Flour is one of the oldest mills in Thailand and produces more than 250 tons of grain daily. Due to their design and reliability the company is a loyal user of AERZEN positive displacement blowers and they have already convinced other companies in the milling industry of the qualities of these blowers. The former favourite of Siam Flour, the 2-lobe GMb15.10, is now being replaced by the more ...

  • Innovations `made in Aerzen`

    In 1987, with the three-lobe blowers, AERZEN introduced an important new product. These patented blowers for conveying large volumes of air, beginning at 3,000 cubic metres intake volume per hour, worked with a controlled pre-inlet particularly well in the low frequency range - they were quiet and operated with little vibrations. This allowed a considerable reduction in the sound absorption ...

  • From atmospheric pressure to vacuum

    Negative pressure from up to 500 mbar (300 mbar abs.) can already be achieved with one stage. This is possible thanks to the AERZEN positive displacement blowers of series Delta Blower G5, or the newly developed rotary lobe compressors of series Delta Hybrid. A vacuum pumping set is mandatory for pressures below 300 mbar abs., and here a backing pump and a vacuum positive displacement blower are ...

After a period of negotiations ...

  • Ready for a new level of process air efficiency?

    Around 90 percent of the life cycle innovations into the latest series, for blow- costs of a compressor are energy er power with oil-free conveyance of air and costs. Consequently, the best approach for the company, and for better eco-balance, is to reduce energy consumption. AERZEN meets this challenge with its oil-free compressing positive displacement blowers, rotary piston compressors and ...

  • Special machine D 98 V makes negative pressure of -­950 mbar possible
