Setting a new standard for oil-free screw blower technology with our ZS 4, ZS 4 VSD & ZS 4 VSD+

    • The ZS 4, ZS 4 VSD & ZS 4 VSD+ are among the most compact screw blowers on the market, making them the ideal choice for the replacement of your exisiting blower units.
    • Whether your process requires constant or variable air delivery, with our newest generation of rotary screw blowers you don’t need to worry about your process uptime.
    • The joint forces of our highly efficient Permanent Magnet Motor and our newest screw blower element with optimized inlet- and outlet ports result in a more efficient energy use.
    • The oil pump is integrated into the oil-free screw blower element. Whenever the element is running, oil is being pumped around. The oil-injection nozzles and built in oil cooler ensure optimal lubrication and cooling of bearings and gears, resulting in the low mechanical losses and high reliability.
    • The Elektronikon® unit controller is specially designed to maximize the performance of your blowers under a variety of conditions. Key benefits are increased energy-efficiency by lowering energy consumption, reduced maintenance time and increased productivity. Moreover, the SMARTLINK service helps you monitor your features from a distance via mobile or internet and therefore helps you to minimize on-site supervision time.
