Breakthrough in Vacuum Technology: High-Pressure Roots Vacuum Blower Achieves Record 73.5 kPa

For decades, the operational ceiling for standard Roots vacuum blowers in many demanding applications has been constrained by a maximum achievable vacuum pressure of approximately 49 kPa (absolute). While effective for numerous tasks, this limit hindered progress in processes requiring significantly deeper vacuum levels without resorting to complex, multi-stage systems or more expensive technologies.

Shattering the 49 kPa Barrier: Introducing the DSR-VH Series

We are proud to announce a significant leap forward: our newly developed High-Pressure Roots Vacuum Blower (DSR-VH Series). Engineered with precision and innovative design principles, the DSR-VH Series achieves an unprecedented maximum vacuum pressure of 73.5 kPa (absolute). This represents a ~50% increase in achievable vacuum depth compared to traditional Roots blowers, effectively bridging a critical gap in vacuum generation technology.

Key Technological Advancements:

1. Enhanced Rotor Profiles & Clearances: Optimized three-lobe rotor geometry and meticulously controlled clearances minimize internal leakage at higher compression ratios, crucial for reaching deeper vacuum levels.

2. Robust Bearing & Sealing System: A redesigned heavy-duty bearing system and advanced shaft seals ensure reliable operation under the increased mechanical loads and thermal stresses inherent at 73.5 kPa vacuum.

3. High-Strength Casing & Components: Utilizing superior materials and reinforced construction to handle the elevated pressure differentials with exceptional durability.

4. Advanced Thermal Management: Improved cooling pathways and materials manage the higher operating temperatures efficiently, maintaining performance stability and component longevity.

5. Optimized Pulsation Control: Specific design features dampen pressure pulsations more effectively at these deeper vacuum levels, contributing to smoother operation and reduced noise.

Unlocking New Application Potential:

This breakthrough in vacuum pressure capability opens doors for the Roots vacuum blower technology in applications previously beyond its reach or requiring supplementary pumps:

1. Deeper Vacuum Processes: Enhanced capability for processes needing vacuum levels between 50 kPa and 73.5 kPa, previously requiring more complex systems.

2. Increased Efficiency: Potential to replace less efficient or higher-maintenance vacuum pumps in specific pressure ranges, offering lower operating costs and simpler setups.

3. Process Intensification: Enables faster cycle times or improved product quality in existing applications by achieving deeper vacuum quicker or more reliably.

4. Reduced System Complexity: In some cases, the DSR-VH Series might eliminate the need for an additional backing pump stage, simplifying system design and maintenance.
