• Rainwater tank

We would like to introduce the Tōtetsu Rainwater Diverter and Dust Removal Device "Bunryū Type I/II." Large visible dust and debris are removed by a strainer, while contaminants dissolved in rainwater are removed by diverting the initial rainwater and discharging it externally. The "Bunryū Type I" is primarily installed at the top of the tank or on the vertical downspout. If water needs to be sent to a distant tank or if the piping is at a higher position than the diverter, please use the "Bunryū Type II (standard type)." 【Features of Bunryū Type I】 ■ Debris such as leaf litter that flows down with the rainwater is removed by the strainer at the top of the main body, and finer dust is further removed inside the main body, allowing clean rainwater to be directed to storage tanks or infiltration pits. ■ No regular maintenance is required. ■ The water diversion rate can be adjusted as desired using the "knob." ■ Its compact size does not require a special location for installation. *For more details, please download the PDF or feel free to contact us.
