Horizontal Laminar Air Flow is designed to provide a clean and controlled working environment through continuous horizontal, unidirectional airflow. HEPA-filtered air passes uniformly across the workspace from the rear of the unit towards the operator, minimizing contamination during critical laboratory operations. The unit features SS-304/SS-316 construction, a smooth joint-free work surface, two-stage filtration, high-efficiency HEPA filtration, low-noise centrifugal blower, illumination, UV sterilization and differential pressure monitoring. Multiple working chamber sizes are available, with customized dimensions offered according to application requirements.
