1. How much is the demand?
Rotary screw air compressors are particularly durable and can handle large volumes of demand over a long period of time. They are more efficient and durable with less horsepower than piston compressors, but this is noticeable when there is a great demand (ie more than 15 horsepower). Rotary screw air compressors are designed to operate at 100% duty cycle.
2. Is lifetime cost important to you?
Yes, rotary screw compressors can have higher air compressor maintenance costs and / or initial capital costs, but their life is much longer than piston-type compressors. Piston compressors typically last about 10,000 hours before they need to be rebuilt. On the other hand, rotary screw compressors last 60,000-80,000 hours. Rotary screw compressors are known for their reliability and durability.
3. Does the machine work near production staff?
Rotary screw air compressors are known good for their quiet operation. Most rotary screw air compressors come with a bass enclosure as standard, so they usually operate between 65 and 75 dBA. This is much lower compared to other types of compressors, especially pistons that can operate at 80-85 dBA
4. What do you supply for filtration?
Rotary compressors are designed not to exceed 3 PPM, but piston compressors have aged over 10 PPM. Less oil carry-over means that the filter element does not need to be replaced frequently, reducing that part of the maintenance costs.
5. Do you use compressed air all day long? Or will your demand change throughout the day?
- Rotary compressors are becoming increasingly popular due to their efficiency and the ability to meet certain high demands. Many rotary screw compressors are used 24/7 and are the main products of many manufacturers.
- The variable speed drive version has the reliability and durability of a rotary screw without constant demand. This makes it faster and slower depending on the demand at that particular point in time. Compared to the benefits of VSD, yesterday’s controls such as online / offline, modulation, and turn valves have been found to be costly, so this option should be considered whenever demand changes.
Overall, today’s rotary screw compressors have gained popularity due to their efficiency, noise level, and the fact that the cost of this type of compressor has dropped significantly over the past decade. Oil carryover is low, durable and reliable. These are offered in VSD for applications that have different requirements throughout the day. Rotary screw compressors are a valuable investment for manufacturers looking for high-quality, overall cost-effective units.
