For this reason, the new ZS blowers include a fully integrated Neos VSD inverter that automatically adjusts and optimises the air flow to meet demand. In tandem with this, the iPM motor ensures the blower\u2019s performance is energy-efficient, even when it is running at partial load.<\/p>\n<p>The iPM motor has been designed and made in Belgium by Airtec, a division within Atlas Copco\u2019s Compressor Technique business area.<\/p>\n<p>The ZS 4 VSD+ blowers underwent a number of innovative design developments to ensure they are highly reliable and energy-efficient.<\/p>\n<p>For instance, the oil pump is now integrated into the oil-free screw blower element. This means whenever the element is running oil is being pumped around.<\/p>\n<p>As a result, the oil has a cooling effect on the element and increases its energy efficiency. To further enhance performance, the iPM motor includes a liquid cooled housing and oil-lubricated bearings to provide for cool operation and a longer lifetime.<\/p>\n<p>\u201cWith the introduction of the new ZS, we have set a new standard, as they can be used up to a working pressure of 1.5 bar,\u201d says Mark Ranger.<\/p>\n<p>He continued: \u201cIn the past, only custom designed machines could reach this level, but <span class=\"highlight highlight-blue\"><a href=\"https:\/\/engineernewsnetwork.com\/blog\/oil-free-vsd-compressor-offers-up-to-10-more-output-15-lower-energy-consumption\/\" target=\"_blank\" rel=\"noopener\">Atlas Copco<\/a><\/span> is now offering it to customers as standard thanks to our brand new element, which is built around an efficient internal compression principle.\u201d<\/p>\n<p>With the ZS 4 VSD+ customers do not need to worry about any contamination risk to their end product, as every blower is ISO 8573-1 Class 0 T\u00dcV certified and guarantees a 100 per cent oil-free air supply for critical applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Atlas Copco has unveiled its new generation of oil-free low pressure rotary screw ZS 4 VSD + blowers, which are equipped with integrated permanent magnet (iPM) motors.
