The recommended sizing is typically displayed in CFM (cubic feet per minute) at a given PSI (pounds per square inch). It’s important to know the requirements of your equipment and usage to match the correct CFM output. Purchasing a compressor with a higher CFM rating than required may be tempting, but it’s best to stick to the appropriate size to prevent overwear and overheating of the unit.
Ultimately, selecting the right air compressor size will ensure efficient operation and maximum lifespan of the equipment.
Recommended air compressor sizes
When it comes to choosing the right air compressor size, it all depends on the type of work you will be doing. For simple tasks such as inflating tires or powering small tools, a smaller-sized compressor with a tank capacity of 6 gallons or less would suffice. However, for more heavy-duty projects such as sanding or painting, a larger compressor would be needed.
For such tasks, a compressor with a tank capacity of 20 gallons or more, and a CFM rating of at least 7 CFM, would be the ideal choice. Keep in mind that the size of the compressor should also be determined by the types of tools being used and the frequency of usage.
A compressor that is too small for the job will lead to constant refilling and can even damage the tools. On the other hand, a compressor that is too big can be costly and bulky. Overall, the key is to carefully consider your specific needs before making a decision on the right air compressor size.
Steps to blow out sprinklers with an air compressor
