What is a Reciprocating air compressor?
Reciprocating Air Compressor is a type of positive displacement type of air compressor in which air is sucked into a chamber and compressed with the help of a reciprocating piston. The basic working principle of a reciprocating compressor is similar to that of a crankshaft piston. The air flows into the compressing cylinder after passing through the air filter and via a suction valve. The air is then compressed using a crankshaft and a piston and leaves through a discharge valve. The compressed air is then stored in a storage tank.
There are four kinds of reciprocating compressors:
1. Single Acting Reciprocating air compressor
Only one side of the piston is used for the compression of the air and the other side is connected to the crankshaft and not used for the compression.
2. Double Acting Reciprocating air compressor
Both the sides of the piston is used for the compression of the air. As the piston moves, one side compressors the air while the other side sucks in more air from the atmosphere.
3. Single stage Reciprocating air compressor
In this air compressor, the compression of the air takes place in a single cylinder
4. Double stage reciprocating air compressor
In this types of compressor, the compression of the air takes place in two stages i.e. the air is first compressed to some extent in one cylinder and is then transferred to the second cylinder for further compression

ELGi’s reciprocating air compressor profile:
ELGi has a wide variety of single and double staged reciprocating air compressors to suit the needs of Africa’s industries. The compressors are designed for continuous duty application.
ELGi has also adapted a dry crankcase that is totally devoid of oil. This new generation ELGi compressors significantly reduce operating costs and provide high quality Oil free air that eliminates the usage of expensive downstream filters.
These reciprocating air compressors are ideal for customers looking for significant impact on power cost, very low noise capacity, small air demands, and long-running capacity of more than 8 hours a day. Africa boasts of a formidable automobile, textile, food and beverages, paint, plastic manufacturing, CNC operation and metal fabrication industries, all of which can benefit from the reciprocating air compressors.
