As a machine, an air compressor is used to compress normal air into air that is much more pressurized. Depending on the industry tips on choosing compressors that are ideal may vary. Nevertheless, we always need to ensure some of the most important specifications are met. The specifications in question are as follows: Flow (FAD), Pressure / pressure, and motor power.
3 Basic Specifications Tips on Choosing Compressors for Your Business
1.) Flow (FAD)
The first tip on choosing the right compressor lies upon the Flow (FAD) of a compressor. FAD indicates how much air volume can be generated / released by the compressor engine. In compressors with the Rotor Piston type (Reciprocasting) it is usually in Liters per minute (L/Min), while in Rotor Screw compressors it is usually in cubic meters per minute ( M3/Min).
2.) Motor Power
Next, we need to ensure the motor power of a compressor. It indicates how much motor power is used to operate the compressor engine. The larger the motor capacity, the greater the power required to drive the compressor. The proportion of motor power is directly proportional to Flow (FAD). Using units of KW / HP.
3.) Pressure
Last tip on choosing the right compressor is the compressor’s pressure. This shows how much maximum air pressure can be produced by the compressor engine, with units of bar / megapascal (MPa). Pressure is generally inversely proportional to Flow (FAD). Where if we increase the pressure then the flow will tend to fall, otherwise if the pressure is lowered then the flow tends to go up with the same motor power. So the best tips on choosing compressors for your business is to choose one with a pressure capacity greater than the need, but not too high so that the maximum flow is obtained.
Example :
The pressure requirement in the production machine is 6 bar, so choose a compressor with a maximum pressure of 7 bar (spare for a pressure drop of 1 bar). If we choose a compressor with a pressure capacity of 8 bar, the compressor will still be able to operate, but the flow is of course smaller than the compressor with a maximum of 7 bar. The effect of choosing different pressures will affect one of the factors, namely the efficiency of electricity consumption. Usually calculated by SPR (Specific Power Ratio) which means the electrical power required to produce air flow at a certain pressure (kW/m3/min). The smaller the SPR value, the more efficient the compressor.
