Used Air Compressors for Sale

Which Air Compressor is Right For You?

Our vast inventory of air compressors for sale covers multiple varieties, each with unique advantages. We can divide air compressors into two main categories.

1. Positive displacement compressors: These compressors trap air in a chamber and reduce the space, forcing the air to compress. These can be further broken down into:
   1. Piston compressors: Using cylinders to compress air. These units are great for high-pressure and intermittent use.
   2. Rotary screw compressors: Rely on intermeshing screws to compress air. Ideal for continuous use.
   3. Rotary vane compressors: Use a slotted rotor with vanes to compress air. They provide less air but are also cheaper.
2. Dynamic compressors: The dynamic industrial air compressors for sale here rely on accelerating airflow for compression. They can further be divided into:
   1. Axial flow compressors: The axial air compressors for sale here use multiple levels of airfoils to accelerate air and increase pressure. They’re great for very high-volume use cases.
   2. Centrifugal compressors: They use rotating impellers to convert kinetic energy into pressure. Ideal for high-volume and continuous applications.

What Should You Know Before Ordering?

We’ve seen how different types of air compressors come with their own set of pros and cons. Here’s what you should know before you buy.

• Capacity: Will your machine be used continuously or intermittently? Does the compressor type suit your ideal use case? 
• Pressure: Can the air compressor for sale here deliver enough pressure and airflow for your needs?
• Condition: How old is the compressor? What physical condition is it in? Has it been serviced before?
• Noise: Different compressors have varying noise levels.
• Maintenance: The maintenance needs will vary depending on things like age of the machine, how much it has been used, etc.

The great thing about ordering from Revelation Machinery is that you never have to worry about those questions.

From the industrial air compressors for sale here to our collection of fabrication, CNC, and packaging equipment, all of our listings contain up-to-date information.
