How to Select the Right Air Compressor

Air compressors are necessary for different industries as they are used in automation and assembly, agriculture and construction and also in chemical manufacturing. The task of the air compressors is to convert the power from an electric motor or a diesel engine into stored energy form which is later released in the form of pressurized air. Pressurized air from the compressor is used to power other machinery and equipment. When in the market seeking for an air compressor there is the need to pay attention to select the best compressor as a mistake will lead to financial loss on the part of the company. Various kinds of air compressors are available, and thus one’s choice depends on factors such as the capacity of air, the operation methods of the compressor and also their pressure levels. When one is purchasing an air compressor, they also need to determine the cost of a given air compressor, the durability and also the ability of the compressor to balance the capacity of the air they hold and the pressure levels of the air that they release.

Based on their method of operation, there are three types of industrial compressors that one can purchase in the market. One kind of the compressors is the reciprocating compressors which work as positive displacement compressors. They function by reducing the volume of the air thus increasing the pressure as they have pumps driven using pistons which are attached to the cylinders that compress and displace the air. One also, chooses between the direct drive and the belt drive kinds of reciprocating air compressors but it is advisable to purchase the belt drive compressors as they are durable and also effective. The reciprocating compressors are not only effective but also portable and suits the construction traders.

The second type of compressors is the rotary screw compressors which also function by positive displacement process. The rotary screw compressors are reliant on helical screws rather than the pistons and thus have less surges and vibration in comparison to the reciprocating compressors. They are also durable and also easy to maintain while their capacity is also larger than that of the reciprocating compressors. The rotary screw compressors also allow one to control the airflow as they come with variable speeds and are widely used in hospitals, construction sites and factories.

One can also purchase the centrifugal compressors which have a rotating disc which provides the momentum to move and also pressurize air. One can also control the pressure of the air as they have inlet guide vanes. They have wide applications as they are used in automotive, air conditioners and refrigerators.
