Advantages

-Simple, Compact Design:Sturdy construction with few moving parts, easy to access and maintain ,easy to
replace parts, very reliable and durable.

-Direct Axial Coupling to the Motor:Direct coupling is possible because the high compression ratio permit
slow rotation speeds, eliminating the need for transmission or gears. Fewer parts, mean slower energy
dissipation and simplified maintenance.

-Low Rotation Speeds:Lower speeds reduce vibration, thus diminishing noise and wear, lowering temperature
and eliminating the need for foundations.

-Low Cycle Temperature:Lower temperatures reduce wear,coolant consumption and leakage caused by
distension of parts.Less energy is needed for cooling, and the purity of delivered air is enhanced.

-Low Need for Maintenance:With fewer parts suffering little wear, single-stage rotary units offer cleaner and
more reliable operation, significantly reducing maintenance needs.
