After how many washes should you discard a bag filter?

In filtration systems, bag filters are designed to capture and hold particulate matter from liquids like fuel or water. The effectiveness of a bag filter decreases with each wash or use, as the pores can become clogged with contaminants, reducing its flow rate and filtration efficiency.

The typical guideline for discarding a bag filter is after a certain number of washes. Option B indicates that a bag filter should be discarded after 6 washes. This number reflects a balance between maintaining effective filtration and avoiding potential failures that could arise from excessive use. Each wash can lead to wear and degradation of the filter material, ultimately compromising its integrity. Discarding the filter after this recommended number of washes helps ensure that filtration remains effective and system performance remains optimal, preventing issues such as ruptures or bypass.

Other choices suggest higher numbers of washes, which would potentially lead to using filters beyond their capacity, risking contamination of the system. Adhering to the guideline of 6 washes allows for reliable operation and protects the overall integrity of water and fuel systems.
