What is the first stage in the three stages of the filtering process?

In the context of the filtering process, the first stage typically refers to the initial level of filtration that removes larger particulates and contaminants from the fuel. This initial stage is crucial for protecting the subsequent filtration systems by preventing clogs and ensuring the overall quality of the fuel entering further processing.

Choosing elements as the first stage reflects an understanding that they are designed to capture larger debris and impurities effectively, providing a foundational layer of filtration. Elements are often constructed from materials that can withstand various operational conditions while still ensuring that larger contaminants are retained, allowing cleaner fuel to proceed to the next stages of filtration.

This foundational aspect of elements makes them integral to the overall efficiency of the filtering process, as they set the standard for the fuel quality that will be worked on in the following stages.
