What to know before Buying an Air Compressor

Buying an air compressor requires time and efforts. You have to compare several brands and find the technology that suits your compressed air requirements.

Whether you are a DIY enthusiast, a professional, or an industrial user, selecting the right air compressor is crucial for the efficiency and longevity of your tools.

By reading this air compressor buying guide, you will learn everything you need to know about compressed air before purchasing an air compressor. At the end of this blog, you will be informed enough to choose the air compressor meeting your needs.

Air compressors are versatile tools that convert power into potential energy stored in pressurized air. You can apply this compressed air to several works. Some of them are to power various pneumatic tools, from nail guns and paint sprayers to industrial machinery.

The very first factors to consider when choosing an air compressor include the capacity, measured in cubic feet per minute (CFM), pressure, expressed in pounds per square inch (PSI), and tank size.

The first step in selecting an air compressor is to determine how to use it. Are you planning to use it for light home improvement projects, professional contracting work, or industrial applications? The intended use will dictate the size, power, and type of compressor you need.

Air capacity and air flow must be define from the very beginning, to determinate the compressor's ability to power tools. The air capacity defines the volume of air the compressor can deliver. The pressure refers at which pressure the air goes out of the compressor.

Different tools varies in terms of amount or compressed air required, as well as, at which pressure they need it. For this reason, it's essential to choose a compressor that meets or exceeds these requirements.

The tank size of an air compressor affects how long you can use your tools before the compressor needs to refill it. Larger tanks provide more air and require to be fulfill less frequently. For these reasons, they are ideal for continuous or heavy-duty use. Smaller tanks are more versatile but may require more frequent refilling.

Air compressors can be powered by electricity, gasoline, or diesel. Electric compressors are suitable for indoor use and areas with easy access to electricity.

Gasoline and diesel compressors are ideal for remote worksites where electricity may not be available. For instance, gasoline and diesel machines are widely used in constructions and agriculture applications. 

Portability is a crucial factor for contractors and homeowners who need to move the compressor between job sites. Portable compressors are typically smaller and lighter, with wheels and handles for easy transportation.

Noise levels can be a significant consideration, especially for indoor or residential use. Some compressors are designed to operate quietly, making them suitable for noise-sensitive environments.

Reciprocating piston compressors are the most common type of air compressor. They use a piston driven by a crankshaft to compress air. These compressors are available in single-stage and two-stage models, with two-stage compressors providing higher pressure and efficiency.

Rotary screw compressors use two helical screws to compress air. They are known for their continuous operation, high efficiency, and low maintenance. These compressors are ideal for industrial applications requiring a constant supply of compressed air.

Scroll compressors use two interleaved spiral-shaped scrolls to compress air. They are known for their quiet operation, high efficiency, and low maintenance. Scroll compressors are suitable for applications requiring clean and dry air.

Investing in air compressor accessories and kits can enhance the performance and functionality of your system. Common accessories include hoses, connectors, regulators, lubricators, and additional air tanks. These accessories can help you customize your compressor setup to meet your specific needs.

Proper air treatment is essential to protect your tools and the internal components of the compressor from damage caused by contaminated or moist air. Air dryers, filters, and separators can help remove moisture and contaminants, ensuring clean and dry air for your tools.

Choosing the right air compressor involves considering the size, intended use, and future needs of the compressor. Using a product selector tool can simplify the selection process.

Yes, some air compressors are powered by gasoline engines, allowing them to be used on remote worksites where electricity may not be available.

Air tools driven by air compressors have unmatched power and longevity compared to corded or cordless electrical tools. Properly maintained air tools can last a lifetime, making air compressors a valuable investment.

When buying an air compressor, it is recommended to have some basic tools on hand to get started, such as hoses and connectors for air tools.

Buying an air compressor is a significant investment that can open up a world of possibilities for driving air tools with unmatched power and longevity.

By considering factors such as intended use, the capacity and pressure requirements, tank size, power source, portability, and noise levels, you can select the right air compressor.

Proper maintenance and air treatment can ensure that your air tools last a lifetime, making air compressors a worthy investment. For more detailed information, you can get in touch with our experts today.
