Lifespan & Troubleshooting FAQs
Q1: My filter's lifespan is shorter than expected. What could be the reason?
A: Common reasons for reduced service life include:
High Humidity: Using standard media in a damp environment causes dust to cake and block the media.
Chemical Attack: Exposure to acids, oxidants, or solvents beyond the media's tolerance (especially the standard version) degrades the fibers.
Abnormally High Dust Load: The system is overloaded, beyond the filter's designed capacity.
Incorrect Differential Pressure Settings: Pulse cleaning cycles that are too infrequent or too frequent can impact life.
Q2: I see dust downstream of the filter. Is the filter faulty?
A: This is called "dust bleeding." Potential causes are:
Improper Gasket Seal: The filter pack is not seated correctly, allowing dust to bypass.
Media Damage: Holes in the media from chemical degradation, physical damage during installation, or highly abrasive dust.
Lack of Pre-coat: On a new or deeply cleaned filter, fine particles may initially pass through before a dust cake forms to aid filtration. Pre-coating might be recommended.
