In light of growing metropolitan areas, more and more vehicles on the roads and increasing air pollution, efficient filter media are in higher demand than ever to ensure optimum indoor air quality, particularly in public spaces. New norms and testing standards, above all the new ISO 16890, are shaping the industry. The norm bases filter classification on more realistic criteria and also takes into account the energy efficiency during operation of the filter unit.
Sandler’s new synthetic filter medium enAIRsave combines long-term performance and reduced energy usage. Multiple filter layers provide optimum dust separation across the entire width of the medium. The particles are primarily deposited in the coarse meltblown layer as well as the pre-filter layer. Air can still flow through the filter at a relatively low pressure and, consequently, at a reduced energy consumption.
