Filter (some industrial environments are relatively poor, such as corrosive gases, so the air inlet of the air compressor must be set to a harmless and clean place, and some user companies will build air clean rooms) - Air filter (some manufacturers only have filter elements, no assembly) - Intake valve - Host - Check valve (some use mechanical valves, some use solenoid valves, and some do not) - Air storage tank (vertical air storage tanks have partitions, horizontal air storage tanks generally do not) - Oil and gas separator (there are rotary and cylinder types) - Small pressure valve (actually a combination valve of pressure valve and check valve) - Aftercooler - Gas-water separator (some manufacturers directly "save" the gas-water separator and comb valve, ask yourself what impact this will have) - Outlet valve.
There are also solenoid valves used to control the intake valve. In addition, different manufacturers have differentiated control methods (generally international brands pay attention to differentiation, and domestic products are highly homogenized. The competition is not quality, but cost and deception ability). This will be discussed in the post-control section.
The above are the basic components of the air compressor gas circuit. The connecting pipes in the middle do not need to be elaborated in detail. Some manufacturers simply connect the air filter element to the intake valve directly in order to "save materials". This is a very inferior design. For sales personnel, this is one of the places where competitors may attack. As a sales engineer, you must know your products and be familiar with your competitors' products. This is just a basic requirement. Only on this basis can you make a sales strategy that is beneficial to yourself and achieve the purpose of leveraging your strengths and avoiding your weaknesses.
