Class H vacuum cleaner: characteristics and scope of use
Dust from classes L, M and H can be collected with one of these vacuum cleaners. They include all dusts harmful to health with an OEL value greater than 0.1 MG/m3, all carcinogenic dusts and dusts contaminated with germs and bacteria.
Specially designed for applications in areas such as small industries, chemical trade, plastics, pharmaceuticals, paper, textiles, tradesmen such as roofers and painters.
A class H vacuum cleaner with minimum Hepa H13 filtration.
Body protection is the most important PPE along with the protective mask to protect against asbestos fibers. The EN ISO13982-1 standard (type 5 impervious to solid particles) is required to protect against asbestos fibers.
But did you know that?
For an
asbestos suit to be type 5 standardized, laboratory tests tolerate up to a 15% leak rate towards the inside of the disposable suit. After the order from the Ministry of Labor requiring waterproof seams, the INRS recommends disposable clothing whose properties guarantee optimal protection.

Conduct of the DOP TEST
1. The vacuum cleaner equipped with the HEPA Filter that is 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 line, a solution of Sodium Chloride is sprayed at approximately 7 bars in aerosol form.
4. The tiny droplets go through the suction of the device, gradually moving towards the testing chamber.
5. When passing through the long tube, the fog formed from Sodium Chloride will dry up, leaving only sodium chloride crystals 0.3µ in diameter.
6. At the heart of this test is a Hydrogen Flame Photometer which allows the air circulating during the operation to be tested.
7. By measuring the concentration of Sodium Chloride crystals present in the air sucked in and rejected by the vacuum cleaner, an exact calculation of the filtration level of the device is carried out.
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 device tested.
