Air compressors are an investment, and it is vital to consider all relevant factors before making the purchase. The most common categories for air compressors based on how they are powered are electric and gas. Gas air compressors are heavy, durable and perform well on heavy-duty jobs with no electricity source on site. These factors make them perfect for projects in remote areas. However, their bulky size means they are not portable and usually require a wheeled structure to carry them. In addition to the lack of portability, they also produce a lot of noise. Electric compressors rely on an electric source to perform and are lightweight and quiet, making them suitable for indoor jobs. Between the two types, gas air compressors are also more expensive than electric air compressors. Within DEWALT Air Compressors, we carry 3 gas powered, 45 electric and 1 battery powered air compressors.
