Four Types of Rotary Screw Compressors that Add Value

Rotary screw air compressors are one of the most commonly-used models of air compressor. Now a cornerstone of the manufacturing world, these compressors come in both oil-injected and oil-free designs. 

The differences in these compressors are fairly obvious for industry experts, but we can dive even deeper to find the true benefits of these tools. There are four subcategories of widely-applicable rotary screw compressors:

1. Base mounted - A base mounted rotary screw compressor is a standalone device typically used in situations where the space available is lacking and a constant flow of compressed air is required. These systems typically don't come with an air receiver tank, and additional dryer configurations can typically be ordered as required to remove any water vapor produced during the process. 
   
   
   
2. 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. Tyipcally, 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.
   
   
   
3. Total air system - Total air systems, sometimes calles 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 intergrated into one compact package. All of these features mark increased convenience for the end user, including a shorter intall time. 
   
   
   
4.  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. 

In addition to what we've referenced in this blog, these types of air compressors are further classified by capacity, voltage, horsepower, and tank capacity (where applicable). Now that you know what each brings to the table, take advantage of the wide variety available on our Compressor World website to find your perfect tool.
