Great Rotary Blower
1. Features a large-radius involute-type impeller with an advanced and rational design, ensuring high overall efficiency.
2. Key components are machined using machining centers and CNC equipment. Gears are precision-ground lightweight alloy steel with Grade 5 accuracy, ensuring high product precision and reliable operation.
3. The oil tank incorporates innovative structures like an oil sump tray for superior heat dissipation. It can operate without cooling water even at 49kPa boost pressure, reducing operating costs.
4. The casing and end plates feature a horizontal center-split design for easy maintenance.
The ZR Series Roots Blower is a new product developed by our company, leveraging years of manufacturing expertise to meet user demand for high-flow, high-pressure blowers. This series integrates the technological essence from the RR Series and L Series blowers—both produced using imported technology—and employs specially designed impeller profiles to create a highly efficient, energy-saving Roots blower.
