Compressed Air Blowers
ZS 4, ZS 4 VSD and ZS 4 VSD+ (37-90 kW / 50-120 hp)
Energy costs can add up to 80% of the lifecycle cost of a blower. That’s why Atlas Copco constantly develops new blower models, consuming a minimum level of energy, such as the ZS VSD+. The Atlas Copco oil-free screw blower element is driven by the in-house developed liquid cooled permanent magnet motor. Combined with the Neos VSD inverter, this successful energy-efficient variable speed driven solution runs trouble-free in the harshest environments. With the ZS VSD+ there is no need to worry about process uptime and no hidden surprises will occur when receiving the energy bill at the end of the month.
Most energy-efficient variable speed driven blower in the market
Atlas Copco took again a next step in the development of energy-efficient low-pressure solutions. The introduction of integrated permanent magnet motors results in the most energy-efficient variable speed driven oil-free screw blower in the market.
Durable and reliable design
Every design choice is driven by composing reliable and durable solutions. The permanent magnet motor housing is foreseen with a liquid cooled jacket to keep it cool in any circumstances. The oil pump is fully integrated ensuring exactly the right amount of cooled oil to the bearings and gears. Transmission from motor to screw element happens over a gearbox.
