Positive displacement using pistons driven by a crankshaft. Single or two-stage.
Rotary Screw
Two intermeshing helical rotors compress air continuously. Oil-flooded or oil-free.
Scroll
Two interleaved spiral scrolls — one fixed, one orbiting — compress air with minimal vibration.
Oil-Less / Oil-Free
No lubricant in compression chamber. Uses PTFE rings, coated rotors, or dry running design.
High-Pressure (Booster)
Multi-stage reciprocating designs that produce 500–6,000+ PSI for PET, breathing air, paintball, CNG.
