The "Halton Sentinel/Sentinel Wall" is an air purifier that utilizes ultraviolet virus inactivation technology, which has been proven effective over time. It can filter indoor air in a short time with a large airflow. By placing filters on four sides, it minimizes noise despite the high airflow, and you hardly feel the airflow. "Sentinel" is a product developed based on the experience and technology that HALTON has cultivated over many years as a manufacturer of ventilation systems for hotel and restaurant kitchens, as well as hospitals. 【Features】 ■ Assuming use in a room of 50m² with a ceiling height of 2.5m, one unit can reduce bacterial concentration to below 5% in 12 to 15 minutes. ■ Despite the large airflow exceeding 1,700m³/Hr, the blower side is equipped with a full filter, allowing for minimal airflow sensation and noise reduction. *For more details, please refer to the PDF document or feel free to contact us.
