Building upon the performance and leak-free reliability of the original ShieldDrive platform, the new SDi Series continues to deliver robust vacuum performance, corrosion resistance and intelligent operation that users have come to expect from NAVAC’s industrial vacuum technology lineup. The pumps utilize NAVAC’s magnetic coupling sealing design to help eliminate oil migration and ensure leak-free operation in critical vacuum environments. 

The newly integrated Quick-Change Oil Mist Filter is designed to minimize oil vapor release into the work environment while streamlining routine maintenance procedures. In addition, the SDi Series now features a detachable oil reservoir system that enables fast and simplified oil changes, reducing downtime and improving long-term serviceability.

“The new ShieldDrive ‘i Series’ was developed with a strong focus on operational efficiency and ease of maintenance,” says Evan Sawyer, director of product at NAVAC Vacuum Technology. “By introducing features like the Quick-Change Oil Mist Filter and Easy Oil Change system, we are helping customers reduce maintenance time while maintaining the high-performance vacuum reliability required in laboratory and industrial applications.”

In addition to the new maintenance features, the SDi Series retains several advanced technologies from the original ShieldDrive platform, including Eco Mode variable-frequency motor operation for optimized energy efficiency and noise reduction, anti-suck back protection, adjustable gas ballast functionality and corrosion-resistant construction for harsh operating environments.

The SDi Series is available in multiple models, including the SD4i, SD8i, SD12i, and SD16i configurations, providing flexibility for a range of vacuum requirements.
