Compressor specifications and testing:
ISO 1217 Displacement compressors – Acceptance tests
ISO 5389 Turbo-compressors – Performance test code
ISO 7183 Compressed air dryers – Specifications and testing
ISO 12500 Filters for Compressed Air – test methods
ISO 8573 Compressed Air – Contaminants and purity classes – test methods
Compressor types are based on reliability, energy efficiency maintainability with cost effectiveness for pressure application from low, medium and higher pressure.
Types of air compressor :
Reciprocating Piston displacement and rotary compressors.
Rotary compressor : Positive displacement compressor in which gas admission and diminution of its successive volumes or its forced discharge are performed cyclically by rotation of one or several rotors in compressor casing.
Reciprocating compressor : positive displacement compressor in which gas admission and diminution of its successive volumes are performed cyclically by straight-line alternating movements of moving member in compression chamber.
1.Piston displacement compressor
2.Oil free compressor
3.Oil Lubricated compressor
4.Screw compressor
Compressor industrial applications :
1) Corrosive Environment
2) Hazardous Environment – combustion and / or explosion risk
3) Extreme / High Temperature
4) Marine Environment
5) Weather-protection
