Air Compressors

Overview

Air compressors are equipment that intake air then liberate that same air at a higher pressure. The usage of air compressors have been increased in almost every industries including construction, food and beverage, automotive industry, in hospitals, mining, agriculture, consumer goods, pharmaceutical, electronics, education, and other fields. Small-scale air compressors can be used for pumping up tires and to power hand tools, like grinders, drills, and nail guns. Compressed air is used directly in applications like sandblasting and spray painting. It is also used in very straightforward ways, such as inflating tires and filling scuba air tanks. There are several companies that manufacture quality air compressors. Choose the best air compressors based on your needs and budget.

How it Works

Air compressors are classified into several types based on their mode of operation that include reciprocating compressors or piston-type compressors, rotary screw air compressors, and centrifugal compressors. Reciprocating compressors are also known as piston-type compressors that are driven by pistons. These pistons are used to compress air in the cylinder, which is then forced into a high-pressure storage tank. Piston driven air compressors are the oldest and most affordable type of air compressor. Small home workshop compressors are normally piston driven.

The next type is the rotary screw air compressors that use twin screws, sort of like oversized drill bits turning next to each other, to increase air pressure. These air compressors have been more expensive than piston-type compressors until recently. Both of these air compressors are available in two-stage models as well. Two-stage compressors condense the air twice the amount and increase the pressure and air flow.

The third major type of air compressor is the centrifugal compressor. Centrifugal compressors come with turbine engines, hence, quite expensive. They use rotating blades to generate high pressure, and are used exclusively in huge industrial applications, because they are only economical for large-scale applications.

Benefits

There are many benefits in using air compressors. They are lighter and easier to use.

Since the motor is in air compressor, it does not generate a lot of heat making it feel cool while using. Small air compressors are very advantageous because they are portable and can be taken to construction sites or any other place. Large air compressors are ideal for big factories.

Costs

The cost of air compressors depend on the type of compressor that you choose to buy. Air compressors prices start at around $100 and may go up as high as $5,000. Other expenses include cost of maintenance, electricity, and operating costs. It would be preferable to go in for an efficient air compressor, even if it is costly, because it may prove to be cost effective in the long run. A fully loaded air compressor can cost up to $350.00.

Timing

The right time to buy an air compressor depends on your individual needs. You have to decide if using a compressor may save you a lot of energy than using power tools before you purchase it.
