Advantages of Screw Compressors

Screw compressors have a number of advantages over other compressor designs. For example, reciprocating or piston compressors use an up and down/motion to create pressure. However, when a piston is going through a down stroke movement, this expends energy without adding to the compressed air flow. Screw compressors use a shaft rotation, which means that all movement contributes to the compression of air. This is more efficient, producing pressure at a reduced cost.

 

Other advantages include:

 

• Noise Levels: Due to the smooth movement of the rotating shaft, screw compressors produce much less noise. BOGE's patented whisper quiet technology reduces this noise further. In fact, some of our models produce as little as 69db.

 

• No Pulsation: With a smooth rotating motion, a screw compressor produces a continual flow of air with no pulsing. Compressed air often pulses when created via piston compression.

 

• Continuous Operation: Screw compressors are ideal for situations that require continuous operation rather than intermittent use.

 

• Control Output: Because of the smooth flow rate, screw compressors offer simple and fluid control of air volume, making it one of the most precise designs in air compressor history.

 

• Low Vibration: The rotational nature of the screw means that vibrations are minimal, making it an excellent solution for sensitive environments where vibrations can interfere with equipment.

 

• No Abrasion: Unlike piston compressors, screw compressors have little wear and tear because of the continual, smooth rotation of the central screw shaft. This results in few repairs and even fewer replacements being needed.
