Our AGM Battery Start-stop Vent Plug is specially designed for start-stop vehicles, ensuring safe and efficient pressure regulation within the battery，meeting the demanding requirements of modern start-stop battery technology, where frequent cycling and high-pressure conditions demand superior reliability.

1. The main function of the PE/PP Filter Flame Arrestor is to prevent airborne particles, dust, or other impurities from entering.
2. In the working process of a battery, which may release gases, ensuring the unobstructed gas passage in plastic battery accessories such as safety valves is crucial.
3. The PE/PP Filter Flame Arrestor effectively captures and prevents the entry of tiny particles, contributing to the maintenance of performance.
4. It exhibits strong corrosion resistance: Filters typically possess good chemical stability and corrosion resistance, enabling them to function effectively in various environmental conditions, including situations with potentially corrosive substances.
5. Ease of replacement: Similar to some safety valve designs, the PE/PP Filter Flame Arrestor may be designed as a replaceable component. This allows users to perform maintenance operations relatively easily when a filter replacement is necessary.

Flame arrestor Principle:

Filtration Principle: The PE/PP Filter Flame Arrestor is made of polypropylene material with a specific porous structure. Its pores are of a certain size distribution, which allows gases to pass through while blocking solid particles and liquid droplets. When the gases generated during the charging and discharging process of the lead - acid battery pass through the PE/PP Filter Flame Arrestor, the solid particles and liquid droplets in the gases are trapped by the filter due to the sieving effect of the pores, while the gaseous components can continue to pass through the filter and be discharged or recycled.

Diffusion - Adsorption Principle: In addition to the physical sieving effect, the PE/PP Filter Flame Arrestor also has a certain adsorption capacity for some substances. The surface of the polypropylene material can adsorb some polar molecules or small - sized impurities in the gas through van der Waals forces and other interactions. This helps to further purify the gas and improve the filtration effect.

Functions

Gas Filtration: The primary function of the PE/PP Filter Flame Arrestor is to filter the gases generated in the lead - acid battery. During the charging and discharging process, the battery may produce gases such as hydrogen, oxygen, and water vapor, which often contain small amounts of acid mist, lead particles, and other impurities. The PE/PP Filter Flame Arrestor effectively removes these impurities from the gas, preventing them from being discharged into the environment and causing pollution and corrosion.

Acid Mist Suppression: In lead - acid batteries, the evaporation of sulfuric acid can form acid mist. The PE/PP Filter Flame Arrestor can effectively capture and retain acid mist droplets, reducing the emission of acid mist. This not only protects the surrounding environment and equipment from acid corrosion but also improves the working environment and safety.

Moisture Regulation: The PE/PP Filter Flame Arrestor can also play a role in regulating the moisture content of the gas. It allows water vapor to pass through to a certain extent while preventing excessive moisture from escaping or entering the battery. This helps maintain the appropriate internal humidity of the battery, which is beneficial to the normal operation and service life of the battery.

Protecting the Battery: By filtering out impurities and regulating the gas composition, the PE/PP Filter Flame Arrestor helps to maintain the internal cleanliness and stability of the lead - acid battery. This reduces the risk of internal short - circuits, electrode corrosion, and other problems caused by impurities, thereby prolonging the service life of the battery and improving its performance and reliability.
