New Video: Filter Maintenance Critical To Optimum Vacuum Performance

Although filters are one of the most vital components of an industrial vacuum cleaner, operators often neglect their maintenance. Even the most efficient industrial vacuums require regular filter upkeep and scheduled replacements to maintain optimal performance. This is even true for high-performance vacuums with multi-stage filtering capabilities. Nilfisk produced this video to provide information on how to properly maintain industrial vacuum cleaner filters.

Properly maintained filters allow the motor to run efficiently and last considerably longer. The working air stream provides a cooling airflow to the motor.

Because every application affects filter life differently, it is ideal to monitor wear over time to determine whether the replacement scheduled needs to be modified. Under normal intermittent usage, paper bags should be changed when the bag is about 2/3 to 3/4 full. A vacuum’s main cotton or polyester filter should be changed every three to five years. Main filters can be washed a few times during their lifecycle using a mild detergent, but must be air-dried to avoid shrinkage. Micro filters should be replaced at least every three months.

Commercial operators should change High Efficiency Particulate Air (HEPA) or Ultra Low Penetration Air (ULPA) filters at least once a year. Household users should replace these filters every three to five years. The video can be viewed here
