How often should filter cartridges be replaced?

Replacement intervals depend on operating conditions, contaminant load, and pressure drop. Regular monitoring and our technical support can help optimize maintenance schedules and reduce downtime.



Can LOONG’s filter elements be used for pre-filtration, membrane filtration, and final filtration? How do I select them accordingly?

Yes, LOONG’s filter elements can be used for pre-filtration to final filtration stages. They can be selected based on the pore size of the filter cartridge, the filtration media or membrane and the format of construction.

 

What kind of construction configurations are LOONG’s filter cartridges available in?

LOONG’s filter cartridges are available in 4 different construction configurations: depth, pleated, pleated-depth and string-wound or spiral-wound.


Are LOONG’s filter elements disposable?

Yes, LOONG’s filter elements are disposable.

 

How to store the filter cartridge?

 Store at a temperature between 5 and 30 °C (4l and 86 °F) in dry conditions

 Do not expose direct sunlight, radiation or direct weather conditions

 Store in original shipping bag and boxingExercise care during handling to avoid physical damage.

 Ensure shipping bags and any seals are intact prior to use. Plastics can be damaged if roughlyhandled, particularly at sub-zero temperatures. Thermal shock by quickly raising the temperature from subzero conditions should also be avoided.

 Visual inspection of packaging and product and, where appropriate.integritytesting is recommended prior to use. Do not use damaged articles.
