How long should the hose be
To choose the correct air hose length, it is important to understand the total distance between the location of use and the work area where the air tool will be used. The greater the distance of the air tool from the air compressor, the greater the air pressure loss. So consider the length to make the tool easy to use. For example, you would choose a long hose to paint vehicles in a large body shop. Air hose, on the other hand, serves in fixed workstations that require less movement. This reduces the distance between the air supply source and the tool, reducing potential pressure losses. While providing sufficient airflow for the tool to operate properly.
What is the correct inner diameter
Flexible air hoses are measured by their inner diameter. The larger the inner diameter, the greater the airflow. In addition, the inner diameter affects the overall weight of the hose.
Working pressure
The pressure resistance of a flexible hose is a safety issue. The max working pressure of the hose must be greater than the max working pressure of the air tool or equipment. So you should select the hose based on the highest pressure that it can withstand. The regulator can reduce the hose pressure to an air pressure lower than the system air pressure. However, the regulator setting can be easily changed. So be sure to determine the system working pressure.
What material is best
The material used to make the air hose will greatly affect its flexibility, weight, and durability. If the material is not suited to the working environment in which it is used, it will quickly deteriorate or perform poorly.
