Designed for laboratories that are difficult to vent due to location, Protector® Echo™ operates independent of building's exhaust system and without removing tempered air from laboratory. Neutrodine™ filters handle jobs of 6+ other kinds of carbon filters, and sensor package, backup filters, and optional g-Guard® remote monitoring software work with range of chemicals. In case of chemical breakthrough or loss of airflow, alarm sounds and communication system alerts designated email address.
