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.
