Oil-free Rotary Lobe Blower ZL (VSD)

Rotary Lobe Blower ZL (VSD)

The Atlas Copco ZL (VSD) oil-free rotary lobe blower delivers reliable, efficient and consistent low-pressure air for a wide range of industrial applications. Its proven tri-lobe positive displacement technology provides low-pulsation airflow, while Variable Speed Drive technology adjusts blower output to match actual air demand.

Oil-free Rotary Lobe Blower ZL (VSD)

Designed for continuous operation, the ZL (VSD) combines robust construction, easy maintenance and compact installation with efficient performance.

The advantages of ZL (VSD) rotary lobe blower technology

The trusted tri-lobe technology with its simple, reliable design is easy to service and requires a low capital investment. It has been used for over 20 years in numerous applications such as wastewater treatment, pneumatic conveying systems, and different industrial processes.

Reliability in harsh environments

Operation in high-ambient temperature environments or at high-altitude is not an issue for ZL rotary lobe blowers. The cooling system and integrated safety and start-up valve contribute to trouble-free operation during the lifetime of the blower.

When starting the unit without a frequency converter, the forces applied to gears, bearings, and other critical components can be substantial. Our start-up valve ensures a gentle start each and every time. It improves reliability and makes intermittent operation – with regular starts and stops – a non-issue for our ZL lobe blowers.

Compact air blowers

Our new ZL rotary lobe blowers have been designed to maximize user-friendliness and minimize the footprint. Our newest generation of rotary lobe blowers occupies 30% less floor space, making them one of the smallest and most compact lobe blowers on the market.

We offer you the option of an outdoor canopy so that your lobe blower units can be installed outside and close to your technology.

Plug and play solution

The integrated variable speed drive controller with Elektronikon® Mk5 panel makes the installation easy, connecting just one cable. This shortens the installation and start-up and saves on installation costs.

Optimal cooling

The newly designed canopy with improved cooling makes our lobe units suited for use in ambient temperatures of +50 °C / 120 °F. On top of that, the integrated controller provides you with a plug-and-play solution with only a minimum of floor space required, helping you save on installation costs.

Efficient operation

The Variable Speed Drive with an integrated controller contributes to smooth and cost-effective operation by providing your application with just the right amount of air. Our units are configurable with IE 3 or NEMA premium energy efficiency class motors.
