Here are Features to specifically look for when choosing an Air Compressor

  1. ASME (American Society of Mechanical Engineers) tank
  2. Belt-driven Air Compressor — Belt-driven compressors generally have a longer life, with less vibration and heat transferring from the motor/engine to the pump.
  3. Cast iron cylinder or cast iron pump sleeves — Cast iron is typically the standard material for cylinders
  4. V-design cylinders -- V-design cylinders typically run cooler that in-line cylinders. Heat is a compressor's worst enemy.
  5. Vertical vs. horizontal air compressors -- Vertical compressors usually take up less floor space than horizontal compressors. Typically, vertical compressors are stationary, whereas smaller horizontal compressors are better for portable applications (such as a truck-mounted compressor).
  6. 100-percent Continuous Speed operation vs. Auto Start/Stop operation -- Auto start/stop operation has preset cut in/cut out pressures. The compressor actually stops and turns back on as air is needed. With constant speed operation, the compressor runs 100-percent of the time and simply adjusts the air output. Dual control compressors offer both auto start/stop and continuos speed operation.
  7. Fully packaged unit with premounted and prewired magnetic motor start, dual control, belt guard mounted air cooled after cooler and electric condensate drain
  8. Low-oil shutdown prevents downtime and costly repairs resulting from low oil levels
  9. Oil-Free (or Oil-less) compressors are virtually maintenance-free performers for light- to general-duty applications. No need for periodic oil changes.

How to figure out your CFM (cubic feet per minute) Requirements:

The table below shows some common air tools and their average CFM measurements. Use this table to determine what continuous CFM rating is required of your air compressor. Air tools are often rated as "Average CFM." "Average CFM" is normally based on a 25% duty cycle (15 seconds out of a minute). This sometimes creates a problem with tools that are used continuously (for example, die grinders, orbital sanders, etc). Nailers and impact wrenches usually do not have the same issue since by design they are used more intermittently. If you plan on using an air tool continuously, it's a important to multiply the "Average CFM" by 4 to get a continuous CFM rating for the air tool.
