What is a feature of screw compressors?

Screw compressors are designed to provide a more efficient and continuous flow of compressed air or refrigerant, which allows them to have a higher capacity than reciprocating compressors. The mechanism of screw compressors involves two interlocking rotors that compress the air as it moves through the machine, enabling them to handle larger volumes and operate more smoothly compared to the cyclic operation of reciprocating compressors. This characteristic makes screw compressors particularly suitable for applications that require a stable and constant supply of compressed air or refrigerant, especially in large-scale industrial operations.

Given this context, while other features like variable load handling and lubrication needs are true for screw compressors, the primary distinguishing feature in comparison to reciprocating compressors is their ability to deliver a higher capacity. This efficient design leads to better performance in applications where large volumes are crucial.
