PRODUCT DETAILS

Features

Maximized Uptime

Designed for long life and minimal maintenance, it ensures smooth, reliable operation with up to one year of maintenance-free use in clean applications. Advanced sealing, low oil consumption, and optimized thermal management reduce wear, extend component life, and lower operating costs for more uptime and value of investment.

Low Noise Operation

Enhances workplace comfort by operating quietly at levels as low as 52 dB(A), making it ideal for noise-sensitive environments like laboratories and cleanrooms, and production floors. It reduces noise pollution and supports compliance with sound level standards without sacrificing vacuum power or efficiency.

Proven Compact, Rugged Design

Built for demanding industrial environments, the compact design delivers durable, clean, quiet solutions and reliable vacuum generation.

Full Adaptability

Offers flexibility with a range of accessories designed to optimize performance and simplify integration. Compatible with external frequency converters, optional adapters for system integration with pumps, and service indicators to monitor oil level, temperature, and filter status.

Built-In Clean Technology

Engineered for cleaner, more efficient operation with minimal maintenance, the pump features integrated exhaust filtration built into the oil casing to simplify installation and reduce system complexity. Its sealed internal design prevents oil loss and emissions, while optimized pump temperatures enable condensation-free vapor handling to protect components and ensure process reliability.
