Introduction
This document outlines the benefits and operational principles of a centralised high-vacuum extraction system designed for portable tools. The system aims to ensure a safe working environment by preventing dust build-up, thereby reducing the risk of fire or explosion.

Specifications and Components
The system includes NEUMATIC® JE – JR dust collectors with automatic cleaning via compressed air, which are essential for a centralised cleaning system. The NEUMATIC® JK 8 – 16 models feature filter cartridges cleaned by compressed air, suitable for high-vacuum extraction systems. Additionally, the NEUMATIC® JK 10 is a pneumatic transport receiver for small tonnages of granules and powders, with optional explosion risk handling features.

Operating Principle
The high-vacuum extraction system captures pollutants at the source during operations with portable tools such as sanders, grinders, and drills. The system is designed to maintain operator comfort while effectively extracting dust. The extraction power is tailored to specific equipment and workstations using specialised software.

Key Benefits

• Maintains a clean work area, facilitating various operations.
• Improves working conditions and team productivity.
• Ensures a healthy environment by reducing airborne dust.
• Complies with ATEX standards to reduce explosive atmosphere risks.
• Efficiently reclaims dust from processes.

System Requirements
For portable tools, a centralised high-vacuum extraction system is necessary, differing from stationary machine systems. Portable tools require lower air flow rates and higher pressure drops, necessitating a vacuum pump or depressor and a circular dust collector. The system connects portable machines to the centralised extraction system via flexible hoses, with fresh air compensating for extracted polluted air.

Conclusion
Implementing this centralised high-vacuum extraction system ensures the health and safety of operators by effectively managing dust and reducing associated risks.
