MANN+HUMMEL air filters for room ventilation systems now comply with the latest fire safety standard EN 13501 class E (normal flammability). An external fire safety assessment confirms that MANN+HUMMEL air filters, both individual components and the filter as a whole, do not increase the risk of fire spreading or the development of smoke gases in the case of a fire.
Explaining the development in details, Frank Spehl, Director of R&D Europe for the Life Science & Environment Air Filtration division at MANN+HUMMEL, said, “In order to guarantee the efficient and, above all, safe operation of a HVAC system, building operators should definitely consider an air filter’s fulfilment of fire safety standard EN 13501 alongside filter and energy efficiency.”
The fire safety of room ventilation systems in buildings is regulated by EN 15423. For air filters, it states that materials must be classified regarding reaction to fire under EN 13501-1.
EN 13501 has replaced DIN 53438, which is still cited in many tenders today. EN ISO 11925-2 continues to be used as the basis for testing, but smoke development and dripping are now also evaluated. Both are important additions to preventative fire safety that were not taken into account in the old DIN 53438. Components that give off a large amount of smoke or drip when burning significantly increase fire risk to humans.
