摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air. A motor is positioned within a main body of the housing, and a pump is positioned within the main body of the housing and operatively coupled to the motor. The pump is driven by the motor to pump air into the tank. A pressure gauge is supported by the housing and includes an automatic shutoff feature. The pressure gauge is in fluid communication with the tank. When a predetermined pressure within the tank is reached the automatic shutoff feature is activated to stop the motor.

摘要： A drain clearing air gun includes a housing defining a main body, a handle positioned on a first end of the main body, and a nose positioned on a second end of the main body. A tank is at least partially positioned within the housing and includes a chamber for receiving pressurized air, where the tank has a first portion and a second portion that are coupled together to form the chamber. The first portion is disposed within the nose of the housing and is formed of a first material. The second portion is disposed within the main body of the housing and is formed of a second material that is different than the first material.
