The ZMR/ZMH Series is designed as an all-in-one Roots blower unit, eliminating the need for complicated onsite assembly. The compact structure ensures a small footprint, reduced installation time, and ease of maintenance. It is ideal for small and medium-sized plants where space and efficiency are critical.
This series covers a broad range of flow rates (0.45–100.6 m³/min) and pressure levels (9.8–98 kPa), allowing customers to choose the most cost-effective and performance-optimized model for their application.
Thanks to its precision-balanced rotors, high-quality silencers, and integrated vibration dampers, the ZMR/ZMH Roots Blower ensures quiet and smooth operation with minimal pulsation, making it suitable for indoor or noise-sensitive environments.
The blower provides 100% oil-free air, ensuring no contamination in processes such as aeration in wastewater treatment or air delivery in pneumatic systems.
With its lightweight, compact design and vibration isolation system, the blower unit can be installed without anchor bolts or complex foundations, significantly reducing installation cost and downtime.
The blower adopts a grease-lubricated drive end and oil-lubricated timing gears, ensuring long-term, stable operation. Modular components also allow easy access for servicing and replacement.
