The invention discloses a high pressure type intelligent nanometer aerator. The aerator comprises a quakeproof stand. Foundation bolts are evenly arranged at the lower end of the quakeproof stand. A motor and a fan are installed at the end face of the top of the quakeproof stand through bolts. A belt cover is installed at the same side of the motor and the fan, an inlet silencer is connected to the top of the fan through an elastic joint, an exhaust pipeline is arranged on the fan, a driving wheel is installed on an output shaft of the motor, and a driven wheel is connected to the driving wheel through a V belt. The motor works so that the output shaft can rotate to drive a pair of three-blade type impellers installed inside the fan to rotate, and therefore air sucked in the atmosphere isexhausted from an exhaust outlet of the exhaust pipeline, the aeration effect is good, a pressure meter can monitor the pressure in real time, when the load exceeds the set pressure of a safety valve,the safety valve is turned on, fan faults are avoided, the safety is high, the inlet silencer can effectively eliminate noise, and the quiet environment is built for people.
