Rotary screw air compressors are among the most commonly used models in various industries. They come in both oil-injected and oil-free designs, each with its unique benefits. However, there are four subcategories of rotary screw compressors that are particularly beneficial due to their specific features and applications.
The Four Types of Rotary Screw Compressors
Base Mounted
A base mounted rotary screw compressor is a standalone device typically used in situations where space is limited and a constant flow of compressed air is required. These systems usually don’t come with an air receiver tank, but additional dryer configurations can be ordered to remove any water vapor produced during the process.
Tank Mounted
Tank mounted rotary screw air compressors are mounted to an air receiver tank. This tank stores compressed air for instances where the required amount of air increases. Typically, a receiver also has an air drying function that can remove vapor from the compressed air, in addition to a pressure gauge and release valve.
Total Air System
Total air systems, sometimes called TAS, combine the space savings of a base mounted compressor and air storage capabilities of a tank mounted compressor. The compressor, tank, and dryer are all integrated into one compact package, offering increased convenience for the end user, including a shorter install time.
Variable Speed
A relatively recent breakthrough in air compression technology, variable speed rotary screw air compressors come equipped with a motor control drive that regulates the unit’s speed. This means the rotations per minute (RPM) can be changed based on the needs of a specific application or load, increasing energy efficiency and helping control power surges.
Conclusion
Understanding the different types of rotary screw compressors can help you choose the right one for your specific needs. Whether you need a base mounted, tank mounted, total air system, or variable speed compressor, each type offers unique advantages that can add value to your operations.
FAQs
Q1: What is a base mounted rotary screw compressor?
A: A base mounted rotary screw compressor is a standalone device typically used in situations where space is limited and a constant flow of compressed air is required.
Q2: What is a total air system in terms of rotary screw compressors?
A: Total air systems, sometimes called TAS, combine the space savings of a base mounted compressor and air storage capabilities of a tank mounted compressor. The compressor, tank, and dryer are all integrated into one compact package.
Q3: How does a variable speed rotary screw compressor work?
A: Variable speed rotary screw compressors come equipped with a motor control drive that regulates the unit’s speed. This means the rotations per minute (RPM) can be changed based on the needs of a specific application or load.
