The product employs the new bearing rotor design; it has a low start up pressure and high rotational speed (up to 3000rpm), the cleaning effect is very good. Light design of the gun body; it is nickel plated, beautiful and durable. 1. The working pressure is 0.4 0.9Mpa; the optimal working pressure is 0.7Mpa; 2. The working pressure shall not exceed 1Mpa to avoid damaging the tornado; 3. Wash the inside with water after each use to prevent blocking of the pipe; 4. Upon receiving the product, rotate the bearing gently to avoid jamming. Flow regulating valve makes it easier to regulate the air flow and control the rotational speed; the product is convenient to use. Interface: European standard, American Standard, Japanese standard Air Coupling:1/4 Optimal Working Pressure:0.7Mpa(7Bar,100Psi) Rotating Speed of Bearing:Max 3000rpm (Adjustable) Air Consumption:75 NL/min Consumption of Cleaning Liquid:50 ML/min
