The Impact of Not Draining Screw Air Compressors

The Impact of Not Draining Screw Air Compressors
October 16, 2023

Screw air compressors are widely used in various industries for their efficient and reliable performance. However, it is crucial to ensure proper maintenance and operation of these machines to avoid any potential issues. One essential aspect of maintaining a screw air compressor is the regular draining of accumulated moisture or condensate.


Failure to drain the condensate from a screw air compressor can have several adverse effects. Firstly, the presence of moisture in the compressed air can lead to corrosion within the system. This corrosion can affect the internal components, such as the compressor's screws, valves, and pipes, reducing their lifespan and potentially causing malfunctions.


Moreover, the moisture in the compressed air can mix with oil, which is often used for lubrication in screw air compressors. This mixture can result in the formation of an emulsion that can clog filters, valves, and other critical parts of the compressor. As a consequence, the compressor's efficiency and performance may be significantly compromised.

Furthermore, the accumulation of condensate can lead to the growth of bacteria, fungi, and other microorganisms within the compressed air system. These microorganisms can contaminate the compressed air, posing a risk to the quality of the end product or the health and safety of personnel working with the compressed air.


In addition to these technical and health-related issues, not draining a oil free screw air compressor can also result in increased energy consumption. The presence of moisture increases the workload on the compressor, as it needs to compress not only the air but also the moisture within it. This additional workload can lead to higher energy consumption, ultimately impacting the operational costs of the compressor.


In conclusion, neglecting to drain condensate from a screw air compressor can have several negative consequences. It can lead to corrosion, emulsion formation, microbial contamination, and increased energy consumption. Therefore, regular and proper draining of condensate is essential to maintain the efficiency, reliability, and longevity of screw air compressors.
