Overview of Envirco LF Horizontal Flow Clean Bench
Designed for contamination-sensitive environments, the LF Clean Bench delivers horizontal unidirectional airflow and HEPA-filtered air to maintain ISO Class 5 conditions. Its two-piece, vibration-isolated construction allows easy transport and installation, while durable materials, integrated lighting, and quiet, adjustable airflow ensure consistent protection for products and precision work.
Horizontal Laminar Flow for Product Protection
Positive, unidirectional airflow delivers clean, ISO Class 5 air across the work surface, protecting samples, electronics, medical devices, and pharmaceuticals. HEPA filtration captures particulates efficiently, preventing contamination while ensuring a stable, controlled environment for sensitive processes in laboratories, inspection areas, and other critical applications.
Vibration-Isolated Two-Piece Design
Separate blower and table modules minimize vibration transmission to the work surface, enhancing stability for precise work. The modular design allows the bench to fit through standard doorways and simplifies transport, setup, and maintenance while preserving airflow integrity and providing a flexible solution for cleanroom and laboratory environments.
Durable, Operator-Friendly Construction
Constructed from welded metal with corrosion-resistant polyurethane enamel, the clean bench includes clear acrylic side panels, a non-glare work surface, and built-in fluorescent lighting for visibility. Adjustable leveling feet, a solid-state speed controller, and quiet operation (~65 dBA) ensure operator comfort, easy use, and consistent clean air performance.
