No. Excessively high precision means smaller media pores and greatly increased airflow resistance, which can reduce equipment suction, clog cartridges quickly, and increase cleaning frequency and energy consumption; too low a precision fails to capture fine dust and causes excessive emissions. Match precision to the conditions: standard precision for ordinary industrial dust; for strict emission requirements and fine dust, membrane high-precision cartridges are recommended.

Common triggers: 1) Wet, sticky dust that cannot be cleaned, forming hard cake; 2) Over-high filtration velocity causing deep media clogging; 3) Insufficient cleaning pressure or unreasonable pulse interval, incomplete cleaning; 4) High ambient humidity causing moisture adhesion; 5) Aged cartridges with clogged media. Solution: adjust conditions and optimize cleaning parameters; replace cartridges directly when caking is severe.

Somewhat. If cartridges are loosely installed or poorly fixed, airflow impact during operation causes them to shake and collide, leading to cabinet vibration and increased noise. Severe clogging also unbalances duct resistance and overloads the fan, producing abnormal sounds. Fan faults and pipe resonance can also cause noise and should be checked one by one.

Replace immediately if any of the following occur: 1) Media damaged, cracked or punctured with dust escaping the outlet; 2) Severe caking where resistance stays high after washing/multiple cleanings and suction drops sharply; 3) Cartridge deformed or pleats collapsed, seal failed; 4) Media aged/powdered, filtration accuracy lost; 5) Service life far exceeds standard with severely degraded performance.

Mixing is not recommended. Old and new cartridges differ greatly in resistance; airflow favors the low-resistance new ones, leaving old cartridges with minimal flow and accelerated clogging, while overall filtration efficiency becomes unbalanced and the collector's performance suffers; it also shortens the remaining life of old cartridges. Batch replacement is advised.

Anti-static cartridges must be used, and: 1) The whole cartridge is anti-static—both media and cage are anti-static materials to prevent static accumulation; 2) The equipment is fitted with explosion vent panels, spark arresters and other explosion-proof accessories; 3) High-pressure over-cleaning is strictly prohibited to avoid secondary dust lifting and explosion risk; 4) Clean cartridge dust regularly to prevent pile-up and spontaneous combustion.

1) Thoroughly clean before shutdown, removing residual dust from the cartridge surface; 2) Store in a dry, ventilated place, avoiding moisture, rain and sun to prevent media caking and aging; 3) Seal the inlet/outlet to keep dust and debris out; 4) If shut down over 1 month, manually clean once and check seal integrity before restart.

Low temperature alone does not damage standard cartridges, but it easily causes air humidity to condense, leading to dew on the cartridge surface and dust adhesion, causing clogging and caking. In winter, keep the equipment insulated to avoid cabinet condensation, slightly adjust the cleaning cycle, and clear light adhesion promptly to prevent hardening.
