Purchasing the Correct Commercial Air Compressor.

Air compressors have numerous applications in industry and are utilized in various fields, including automation and assembly, chemical manufacturing, agriculture and construction. All compressors work by converting power from an external source, such being an electric motor or diesel engines, into stored energy which can be released in the proper execution of pressurised air. The pressurised air is then used to power tools and machinery.

Choosing the Right Air Compressor

However compressors vary within their method of operation, air capacity and degree of pressure they can deliver. The best compressor will able to put on enough air and deliver a top enough degree of pressure for the job, but performance should be balanced against considerations such as cost and durability. Compressed air is measured in cubic feet per minute (CFM), with a top requirement for CFM needing a bigger air capacity and higher horsepower (HP).

Kinds of Industrial Air Compressor

You can find three major kinds of industrial air compressor based on the method of operation mini fridge compressor These are reciprocating compressors , rotary screw compressors and centrifugal compressors.


Reciprocating compressors are positive displacement compressors , where air is reduced in volume to improve its pressure. Reciprocating contain pumps driven by pistons with a cylinder compressing and displacing the air. You can find two types, direct drive compressors and belt drive compressors. Belt drive compressors are far more durable and in a position to deliver higher pressures. Reciprocating compressors can be purchased in single stage and multi stage. Multi stage compressors deliver higher pressures and are far more efficient, meaning lower electricity consumption and lower costs. Reciprocating compressors are often portable and ideal for trades people involved in construction and similar fields.

Rotary Screw

Rotary screw air compressors also work with a positive displacement process. They choose two helical screws meshed together to force air through and compress it. The method of operation is really a smoother process than that of pistons, with less surges and vibration than that sometimes within reciprocating compressors. They’re durable and simple to maintain. Rotary screw air compressors generally have greater capacities than reciprocating compressors and can deliver higher air pressures. Some types have variable speed drives and therefore airflow and pressure can be closely controlled, and where airflow requirements are variable this may result in significant energy savings. Rotary screw air compressors have various applications, finding used in areas such as construction sites, factories and hospitals.


Centrifugal air compressors work with a different mechanism. They use the momentum gained from a rotating disk to transfer and pressurise air. This method is called dynamic displacement and is really a continuous process, causing a steady method of getting pressurised air. They are able to deliver extremely high pressures. Though the method also requires higher speeds and higher air capacities than other compressors. The capability and airflow can be controlled by way of inlet guide vanes. Centrifugal compressors have many applications, and are used for machinery such as pneumatic drills and automotive superchargers and turbochargers, in addition to for air conditioning and refrigeration. They’re also within gas turbines, gas pipelines, oil refineries, petrochemical plants and chemical plants.
