Introduction

Application


  • Mini Pleat filter panels with hood, type FHD, for the separation of suspended particles such as aerosols, toxic dusts, viruses and bacteria from the supply and extract air in clean room systems with controlled air cleanliness and airflow.
  • Particulate filters: Final filters for the most critical requirements of air cleanliness and sterility in areas such as production, research, medicine, pharmaceuticals industry, and nuclear engineering

Special characteristics
  • Ideal pleat geometry of the filter medium
  • Low-turbulence airflow on the downstream side
  • Leakage test, standard for all particulate filters of classes H13, H14, U15
