If you have used air compressors, you will know that some of the most important factors of a great machine are its portability, efficiency, power consumption and power delivery specifications. The air compressor market today has many machines to choose from. However, for a long lasting and efficient machine it is best to match your needs with functionality of the chosen compressor.
Types of air compressors
1) Reciprocating air compressors â Such compressors use pistons in cylinders to compress air. These compressors may be powered by electricity or petrol and produce force varying from 5 horsepower to 1000 horsepower.
2) Rotary screw compressors â these air compressors use helical screws to compress air. These are simpler devices and are very efficient for continuous use. If you are looking for variety then rotary screw compressors come in portable and fixed models. These compressors are very useful for pneumatic drills and digging devices.
3) Centrifugal air compressors â these compressors use rotating discs with a fan like appearance. These are very high powered devices and find applications in industrial manufacturing, cement plants, fertilizer processing plants and automobiles. You would not need such compressors for a domestic or household purpose.
Points to consider before you purchase an air compressor:
1) Review and research the operating costs of the air compressor. Unless you have large volumes to meet or work in a very demanding environment it is better to stick to compressors which are very cost effective. Operating costs of a compressor include the type of fuel required, the type of lubricant required, heat generation, continuous usage type or single use and reuse type. Air compressors which run on electricity and natural gas are the most cost efficient. They also make the least amount of noise and are smaller and lighter.
2) Decide on the horse power rating that you need for your air compressor. You don’t want to run out of power when you need it the most. It is wise to always choose a compressor which has a higher horse power rating than what you think you actually need.
3) Analyze the pounds per square inch that the air compressor delivers. Remember that if your pounds per square inch are low then most of the common pneumatic devices will not function efficiently. The end result of this would be low quality of the work completed, hence not serving its purpose!
