Class H is the highest filtration class in the field of professional and industrial vacuum cleaners. Particularly necessary or even essential in certain activities such as asbestos removal , the class H vacuum cleaner must meet several standards of construction, filtration, use but also maintenance by certified organizations when use makes it necessary. A class H vacuum cleaner meets strict filtration standards. A Nilfisk or Numatic class H vacuum cleaner provides these guarantees with the EN60335-2-69 standard.

1. The vacuum cleaner equipped with the HEPA filter to be tested is positioned inside the test chamber. 2. Once the vacuum cleaner is connected and turned on, the test chamber is sealed. 3. At the other end of the test chain, a solution of Sodium Chloride is sprayed at approximately 7 bars in the form of an aerosol. 4. The tiny droplets will gradually move towards the test chamber through the suction of the device. 5. As it passes through the long tube, the fog formed from Sodium Chloride will dry out to leave only sodium chloride crystals of 0.3µ in diameter. 6. At the heart of this test is a Hydrogen Flame Photometer which allows testing of the air flowing during operation. 7. By measuring the concentration of Sodium Chloride crystals present in the air sucked in and released by the vacuum cleaner, an exact calculation of the filtration level of the device is made. 8. Each result is individually reported on a test certificate which validates a particle filtration level of 0.3µ to more than 99.995%. This certificate of conformity is attached to the tested device.
Class H vacuum cleaners are part of the industrial vacuum cleaner category, designed to vacuum dust and debris that pose a high risk to health. They are classified according to their ability to filter the finest particles, according to strict European standards. Class H corresponds to the highest level of filtration, with a minimum efficiency of 99.995% for particles smaller than 1 micron.
Class H vacuum cleaners are specially designed to vacuum the finest and most dangerous dusts, such as: • Carcinogenic dust (asbestos, lead, etc.) • Mold spores • Mineral fibers • Very small particles (flour dust, etc.) They are therefore essential for work involving the handling of risky materials , such as the removal of asbestos, interventions in hospitals or milling activities.
Class H vacuum cleaners must meet very strict regulatory requirements, defined at European level. In particular, they must comply with the following standards: • Standard EN 60335-2-69: Safety specifications for industrial and domestic vacuum cleaners for the suction of hazardous dusts • EN 1822 standard: Very high efficiency air filters (EPA, HEPA and ULPA) These standards govern filtration performance, safety of use and verification tests to be carried out on these devices.
Regular maintenance of a Class H vacuum cleaner is essential to maintain its performance and safety of use. Here are the main steps to follow: 1. Empty the waste collection tank after each use 2. Clean filters according to manufacturer recommendations (usually every 6 months) 3. Check for damage to hoses, nozzles and other accessories 4. Perform periodic safety checks (leak test, air flow check, etc.) 5. Follow the manufacturer's recommendations for maintenance and replacement of parts Neglected maintenance can lead to reduced filtration efficiency and even risks of dust dissemination.
