When in the market for an air compressor, customers generally look at features like durability, capacity, efficiency, and price. Among the various types of compressors available, rotary screw compressors often stand out due to their unique advantages.
Higher Specific Power
Specific power is the ratio of power to compressed air flow rate at a given pressure, typically given the units of kW/100 acfm. The lower the specific power, the more efficient the compressor is at given compressed air loads. Rotary screw air compressors have more specific power than other compressors, as much as 134% more than similarly sized reciprocating air compressors. This higher power output means more compact units can deliver the same power, making it easier to fit them into small spaces.
Fewer Moving Parts
Rotary screw air compressors are designed in such a way that they have fewer moving parts than other types of compressors such as reciprocating compressors. Fewer moving parts means fewer things to break, making rotary screw compressors more reliable and less costly to maintain.
Reduced Vibration
Another great advantage of a rotary screw compressor is that it promises reduced vibration, as little as one-thirtieth the amount of vibration as reciprocating compressors. Less vibration means less wear and tear on your compressor and accessories, lowering maintenance costs and the overall cost of ownership.
Less Refrigerant Loss
Screw compressors also promise a reduced risk of refrigerant loss. This happens because the efficient design of a screw compressor allows for tighter tolerances and reduced vibration within the entire system. Less refrigerant loss is one of the biggest benefits that any air compressor can offer.
Conclusion
These are just a few of the advantages that a rotary screw air compressor offers, making them an ideal choice for compact compressors with maximum efficiency.
