When transporting hydrogen peroxide tanks, a 2" H2O2 breather is utilized to vent the tank. Two sintered discs make up this product. When pressurizing the tank during unloading operations, one in the body serves as a filter for the pressurized air. The liquid flow rates pass through the second disc in the event of a tank overturn. The water flow rate is restricted by the second disc. The discs' high filtering capacity limits the liquid flow rate to a maximum of 1 l/h at 0.2 Bar pressure in the tank.
