Air compressors can be broadly classified into two categories: piston compressors and screw compressors. Each type has its own unique working principles and applications.
- Piston (Reciprocating) Compressors: These are the most common type of air compressors. They use a piston driven by a crankshaft to compress air. Piston compressors can be single-stage or two-stage, depending on the level of compression required.
- Rotary Screw Compressors: These compressors use two interlocking helical screws to compress air. They are known for their continuous operation, energy efficiency, and low maintenance requirements.
