The certificates document the dust collection efficiency of SINBRAN® Filter Elements. The IFA is an independent test institute that is specialized on testing according to EN 60335-2-69. The elements are tested at an A/C of 200 m³/m²h. The test dust is quartz sand at a grain load of 200±20 mg/m³. 90% of the particle size is between 0,2µm and 2 µm (Stokes).
SINBRAN® Filter Elements are classified as class M which means that the emission has to be below 0,10% for the test dust.
