Laminar Air Flow (LAF) and Reverse Laminar Air Flow (RLAF) units are designed to provide clean, particle-free airflow for critical operations in pharmaceutical, biotech, and research environments. At SAM HVAC Engineers, we offer LAF systems that direct HEPA-filtered air across the workspace to protect sensitive products. Our RLAF units capture contaminants from hazardous procedures, ensuring operator and environmental safety by drawing air inward and filtering it before release.
