Maintenance and cleaning
Regular maintenance and cleaning are prerequisites for a long service life and perfect function. The regular removal of dust can extend the service life of the filter cartridges. The maintenance interval is determined by the working environment and operating time of the units. If the unit is operated for longer than 8 hours per day, the maintenance interval should be adapted according to requirements.
