COMPRESSORS & COMPRESSED AIR
as there is no need for the provision of noise- insulated rooms and doors. Service and lifetime support: When it
comes to routine maintenance and service support, some older blower technologies may require units to be serviced, repaired or re- furbished offsite. Advanced design developments in the latest oil-free, low- pressure blowers now sees the inclusion of low maintenance components, extended on-site service intervals, and the benefits of lifetime customer support plans. Comparative performances: It pays to
check the vital statistics. As an example, the tri-lobe rotors incorporated into the latest generation of low-noise, low-vibration, low- pulsation blowers are capable of sweeping nearly six times the volume of air in a single revolution compared to their belt-driven, twin- lobe predecessors. On average, this older technology experiences 5% - 7% more transmission losses. An important advantage of the direct-
drive, oil-free, rotary screw blowers is wide turndown, especially on models with integrated inverter drives. This allows the units to match the airflows to the daily and seasonal variations in the effluent inflow, resulting in additional energy savings. In order to cope with fluctuations in air demand, screw blower technology can operate from 100%
The ultimate aim is for a blower system that provides total reliability, guaranteed continuity of process operations, and combines optimum performance with protection of the process, the environment and operational energy costs
capacity to 25% with very little change in specific power requirement. As a practical example of the rotary screw

blower’s superior performance in industry, Frito Lay, an affiliate of PepsiCo Foods in Turkey, achieved an average of 30% energy efficiency, lower operating costs and minimum noise levels by installing Atlas Copco’s ZS screw blower technology within its water treatment facility. Installed back in 2010, there have been no unexpected shutdowns due to failure since the first operation of the blowers. Noise level at
one metre is as low as 70 dB(A). The Atlas Copco ZS rotary screw blower
system delivers 100% oil-free, pulsation-free air, and carries a 5-year warranty of reliability. All ZS+ blowers are complete with an Elektronikon operating system to provide control and enable smart remote monitoring of the overall system performance status, and to increase the blowers’ efficiency and reliability.
