Atlas Copco launches ZS 4 (VSD) oil-free screw blowers for food and beverage production

Fermentation processes require accurate airflow control from minimum to maximum demand, while pressure requirements can increase as the fermentation cycle progresses. Incorporating advancements from VSD+ (variable speed drive) technology, the ZS 4 (VSD) is designed to adapt to these changing operating conditions while maintaining consistent output.

Available in a power range of 37-90 kW, the ZS 4 (VSD) combines a high-efficiency IE4/IE5 motor with an innovative smart pressure split design. With up to 35% greater energy efficiency compared to traditional lobe blowers and a 3% improvement in specific energy requirement (SER), the ZS 4 (VSD) helps customers lower operating costs and reduce total cost of ownership. Performance benefits include stable airflow, even under constant load, and optimised output across varying pressure requirements. Class 0 oil-free compression ensures clean, reliable air, while noise levels as low as 75 dB(A) - due to refined acoustics and internal damping - support improved working environments.

Reliability features include a warranty of up to 5 years on the screw element (up to 60,000 hours - subject to the use of Atlas Copco genuine parts and certified service), robust construction for harsh industrial conditions and reduced mechanical stress for fewer failure points and a longer lifespan.

Compact, quiet, and plug-and-play, Atlas Copco says the ZS 4 (VSD) sets a new benchmark for oil-free blowers. By combining advanced engineering with energy-saving innovations, Atlas Copco continues to support industries in improving productivity, reducing environmental impact, and lowering operating costs.
