An air compressor is a revolutionary device, which is used to convert electric power or gas into kinetic energy by compressing air. The compressed air is then let off in quick bursts. The device is used for a number of purposes, ranging from powering tools like wrenches, paint sprayers or grinders to blowing up toys a snap or inflating car tires. The air compressor is extensively used in offices and shops. But the device can be pretty handy for domestic purposes as well.

The concept of home air compressors is pretty new and most of us are not very much aware about them. Thus, purchasing a right home air compressor can be an uphill task for a layman. Here are some easy tips on selecting a right home air compressor:

Step 1: As aforesaid, the compressor works on a simple scientific formula: compressing a gas (air) into a storage tank and then letting off the compressed air in short bursts. One has to consider that the pressure of that burst should be powerful enough to power a wide range of tools.

Step 2: Carry out a competitive analysis of the compressors on the basis of air flow, which is gauged in CFM (cubic feet per minute) or SCFM (standard cubic feet per minute). An ideal home air compressor should come with SCFM or CFM at 90 pounds per square inch (PSI). It's notable that minor household tools such as nailers need up to 1-5 CFM. The requirement increases to 10 CFM in larger tools.

Step 3: The size of the storage tank is also an important factor. A larger tank will power tools for a longer period of time as compared to a smaller tank. But the requirement is bound to vary with every individual. Say, you need a short burst of air to power tools such as a power nailer or an impact wrench, while a paint sprayer will need a air bursts for a longer period of time and most probably a larger tank.

Step 4: Determine the location where you intend to use the compressor. In case you decide to use the compressor inside home, an electric motor will be a safe option. It's notable that Gasoline-powered compressors are considered as more powerful than electric-powered compressors. However, the gasoline-powered compressors emit relatively lot of fume, making it impossible to use them inside home or building.

Step 5: The weight and shape are also major factors in this regard. Horizontal compressors are lighter and easier to relocate. On the other hand, vertical compressors need less space to store. It's pertinent to mention here that gasoline-powered compressors can be pretty heavier and one may find it difficult move them on own.
