Sunfil Pre Filter

Pre or Coarse filters, also known as rough filters, are available from EU-1 to EU-4 per European Standards. They filter particles down to 10 microns with an efficiency of 85% to 95%. These filters can be installed directly in AHUs or mounted in banks. They use superior quality non-woven synthetic filter media, sandwiched between two HDPE mesh layers, which act as retainers to screen out large particles and prevent them from embedding in the media.
