Hunkeler Compact Aircleaners are the ideal solution for cleaning air in buildings. The HKA filters the entire air volume on average every two to three hours, day and night. The smallest particles are removed from the ambient air and leaves it appreciably improved in quality. Cleaning time in buildings is reduced by up to 60 percent, which means outgoings for cleaning are also reduced. Downtime for machines and production systems are reduced to a minimum thanks to improved cleanliness for the sensors.
