In practice it is common that the manufacturer use standardized receivers for specific compressor models based on their know-how. For calculating the receiver, note that it is necessary with a pressure band for the receiver to be effective. .
The air receiver must in general be sized according 1. the variation in the consumption demand 2. the compressor size and the modulation strategy In general it is possible to calculate the maximum consumption in the system by summarizing the. .
For an air compressor system with mean air consumption 1000 cfm , maximum tank pressure 110 psi , minimum tank pressure 100 psi and 5 sec time for the receiver to go from upper to lower pressure - the volume of the receiver tank can be calculated by. [pdf]
Excavators are also called diggers, scoopers, mechanical shovels, or 360-degree excavators (sometimes abbreviated simply to "360"). Tracked excavators are sometimes called "trackhoes" by analogy to the backhoe. In the UK, wheeled excavators are sometimes known as "rubber ducks".
