High-Temperature Aluminum Flame Arrestor Vent for Gas Station Oil Tanks

High-Temperature Aluminum Flame Arrestor Vent for Gas Station Oil Tanks

Safety and ventilation are critical for modern fuel storage tanks in gas stations and industrial oil depots. The HYSTZ-XXF Series Open Atmospheric Vent Valves are designed with dual built-in aluminum flame arrestor screens, allowing tanks to vent safely while preventing accidental sparks or open flames from igniting flammable vapors inside the tank. These vents maintain proper pressure balance, protect tanks from overpressure, and ensure reliable safety performance for both underground and aboveground storage tanks.

Worldwide, this type of vent is known by various names. In North America and Europe, it is often called a Flame Arrestor Vent or Tank Top Vent with Flame Screen. In Asia, the Middle East, and Latin America, it is commonly referred to as Oil Tank Safety Vent, Flame-Proof Oil Tank Breather, or Tank Top Fire Prevention Vent. Despite different names, the essential function remains the same: providing tank ventilation, preventing fire hazards, and protecting the integrity of storage tanks.

The HYSTZ-XXF Series is easy to install, typically mounted at approximately 4.5 meters above the tank. The body is made of high-strength aluminum alloy, the cap is stainless steel, and the internal foldable aluminum flame arrestor screens deliver exceptional heat resistance, explosion prevention, and long-term durability. Tested under continuous flame exposure, this series has successfully prevented flashback more than 13 times, ensuring reliable operational safety.

Available in sizes from 1.5 inches to 6 inches, these vents can be customized with flanges and female threads according to client requirements. The compact design, corrosion resistance, and wide operating temperature range (-20~+70°C) make them ideal for both aboveground and underground oil tanks.

Key applications include:
Portable and fixed gas stations
Underground or aboveground fuel storage tanks
Industrial and commercial oil storage facilities

With innovative flame arrestor technology and stable venting performance, the HYSTZ-XXF Series Open Atmospheric Vent not only automatically balances tank pressure and reduces evaporation loss but also provides a robust safety barrier for global fuel storage management.
