Respiratory masks are used in many industrial areas to protect workers from inhaling harmful dust and gases in the air. Respiratory contaminants are the leading cause of long-term occupational health issues. The CleanSpace Ultra was developed against the backdrop that respiratory protection design has hardly changed over the past 25 years. The aim was to combine the convenience of a negative pressure mask with the assured protection and comfort of a powered respirator. Weighing only 520 grams, this lightweight mask was developed by biomedical engineers who have miniaturised the core components to encase them in a compact ergonomic device. Thanks to this efficient design, the disadvantages of traditional respiratory masks, such as bulkiness and the obstruction of dangling hoses and belts, could be eliminated. Featuring an elegant design idiom, the CleanSpace Ultra delivers very good on-demand airflow thanks to the proprietary AirSensit system. The respiratory mask is intuitive to wear and durable at low total operating costs. It is thus especially suitable for high-volume deployment and high adoption by work teams in large industrial companies and in remote sites where close training and technical support cannot always be ensured. Balancing functionality with highly advanced ergonomics, the mask thus results in improved respiratory protection – its distinctively elegant appearance yields a high level of acceptance and long-term compliance among workers.
