The Leybold RUVAC WAU 501 is a high-performance Roots blower designed to enhance vacuum systems by providing increased pumping speeds in the fine vacuum range. It serves as a booster stage for forevacuum pumps, effectively compressing large volumes of gases or vapours.

Key Features:

• High Pumping Speed: Delivers a nominal pumping speed of 505 m³/h (357 CFM) at 60 Hz, with an ultimate pressure of less than 3 × 10⁻² mbar.
• Motor Configuration: Equipped with a 3 hp (2.2 kW) motor operating at 50 Hz (2,900 min⁻¹) and 60 Hz (3,450 min⁻¹).
• Flexible Orientation: Designed for versatility, the RUVAC WAU 501 can be installed in either vertical or horizontal positions, adapting to various system configurations.
• Durable Construction: Features rugged bearings combined with a highly efficient lubrication system, enhancing quiet operation and extending service intervals.

Applications:

The RUVAC WAU 501 is widely used in applications requiring high pumping speeds and reliable performance, including:

• Heat treatment processes
• Metallurgical applications
• Large-area coating
• Architectural glass coating
• Monocrystal pulling
• Semiconductor manufacturing
• Solar cell production
