The has the characteristics of high temperature resistance, rust resistance, and sealing In order to that water will not be discharged during the exhaust process, our vent uses a special structure-the design of the steams and water separation tray Our drain be easy to disassemble and maintain The inside of our emptying be high-precision parts, the exhaust mechanism be stable and When the be running with water or the pressure be too high and full drainage be required, this automatic pressure relief can operate reliably As long as there be a pressure difference between the inside and outside of the, the exhaust will continue to exhaust, Manufacturer: Bwuikim
