1. Free venting with automatic pressure balance: Straight or elbow structure provides gas inlet/outlet passage, automatically balancing tank pressure without moving parts, ensuring high reliability.
2. Rain and dust protection design: Top rain cover prevents rain, dust, and debris from entering the tank; optional insect screen prevents insects and birds from entering.
3. Optional flame arrestor function: Can be equipped with stainless steel corrugated flame arrestor element to prevent external flames from entering the tank through the vent pipe, meeting fire protection codes.
4. Large venting capacity with low pressure drop: Large flow cross-sectional area minimizes gas flow resistance, meeting venting requirements during rapid filling and discharging.
5. Multiple corrosion-resistant materials: Body available in carbon steel, stainless steel, aluminum alloy, or plastic (UPVC/PP) to suit various media such as water, oil, chemicals, and outdoor environments.
6. Simple structure with easy installation and maintenance: Standard flange or threaded connections for easy installation; removable rain cover and insect screen for convenient cleaning, low maintenance cost.
7. Wide application range: Suitable for vent piping of atmospheric storage tanks in water treatment, petrochemical, food and beverage, environmental protection, and other industries.
