How to choose the best air compressor for your blast cabinet?
A more reliable factor to look at today is air flow rate, or CFM (cubic feet per minute). Most abrasive blast cabinet operators choose an air compressor based on the horsepower (HP) of the air compressor. In the past, the thinking was that each unit of horsepower would produce 4 CFM, (for example: a 15 HP compressor would produce 60 CFM).
What should I look for in an air compressor?
If your air compressor is too small for the cabinet, it won’t propel the blast media with enough force to strip, clean, or finish a surface. The statistic that you should be looking at when choosing an air compressor for your blast cabinet is the CFM, or cubic feet per minute. This is the volume of air that the air compressor generates.
How many CFM does a 15 hp air compressor produce?
In the past, the thinking was that each unit of horsepower would produce 4 CFM, (for example: a 15 HP compressor would produce 60 CFM). This is no longer true for modern air compressors, most notably for air compressors with 10 horsepower or less.
How long does it take an air compressor to run?
This is measured as a percentage of ten-minute increments. If the air compressor has a duty cycle of 50/50, and the compressor is running for a total of ten minutes, that adds up to five minutes on, and five minutes off. A compressor with a duty cycle of 60/40 can run for a total of six minutes on and four minutes off for each ten minutes it runs.
What causes a compressor to burn out on an Embraco?
This can cause problems, such as the burn-out of the compressor. Always check out the technical sheet of the compressor (click here and check out the electronic catalog of Embraco).
How does an air compressor wear down with age?
As the components of an air compressor wear down with age, the machine as a whole is forced to work harder to complete its basic functions.
What should the temperature of an air compressor be?
If the temperature at the discharge port exceeds 300 degrees Fahrenheit, the refrigerant oil and adjacent mechanisms will suffer. For the health of the air compressor, the temperature at the discharge line should never exceed 225 degrees Fahrenheit.
What causes a compressor to run too hot?
There are several reasons for a compressor to run too hot, including high compression ratio, high return gas temperatures, and lack of external cooling.
