The Sundström SR221 Pre-filter is a high-performance consumable designed to extend the service life of main gas and particle filters. By capturing larger airborne particles, dust, and debris before they reach the primary filter, the SR221 prevents premature clogging and ensures optimal airflow. This simple addition significantly reduces operating costs and maintains the breathing efficiency of the entire respiratory system.
Engineered for seamless integration, the pre-filter sits securely in the pre-filter holder of all Sundström masks. It is a critical component for maintaining high safety standards in dusty or high-spray environments, ensuring that the more expensive main filters remain effective for their maximum rated duration.
