Atlas Copco has unveiled the ZB 5-120 VSD centrifugal air blower. The unit features a variable-speed drive. Included in the new ZB range is an air-foil-bearing technology designed for high energy efficiency.
The ZB range delivers 100% oil-free air according to ISO standard 8573-1 and eliminates any risk of oil-contamination in the aeration system. The air-foil bearings allow friction-free flotation of the high-speed rotor.
