Maintenance and repair:
It should be checked every six months. Check whether the fire-resistant layer has defects such as blockage, deformation, or corrosion;
Clean the blocked fire-resistant layer thoroughly to ensure that each hole is unobstructed. Replace any deformed or corroded fire-resistant layer;
When cleaning the flame arrester core components, high-pressure steam, non corrosive solvents, or compressed air should be used for blowing, and sharp hardware scrubbing should not be used;
When reinstalling the fire-resistant layer, the gasket should be updated and the sealing surface should be confirmed to be clean and undamaged, without any air leakage.
