Description
LEV Sliding Sash Enclosures – Advanced Containment for Laboratory Equipment
LEV Sliding Sash Enclosures from Envirosafe Ireland deliver excellent containment and superior ergonomics for laboratories handling pharmaceutical compounds, potent powders, and precision instruments. Using a patented constant air volume (CAV) sliding sash mechanism, these enclosures allow operators to safely access equipment at different heights while maintaining proven containment and energy efficiency.

Each unit is custom-built to meet customer requirements, ensuring compatibility with a wide range of laboratory processes. Popular applications include HPLC, robotics, particle sizers, lab reactors, rotary evaporators, milling, sieving, and other laboratory instruments used in pharmaceutical research and development.
