PRE FILTER ( HAVC )

Pre filter

Working Principle

Coars / Pre Filters are primary stage of filters used to arrest large dust particles of size down to 10 micron and to filters lints,soot,plant pollen,insects and dust from atmospheric air,Thease filters are classified under DIN EN 779 / ASHRAE 52.2-1999 These filters are used in virtually any air handling applications.

Better filteration is the first step in improving indoor Air Quality. Pleated panel filters outperform ordinary furnace filters with higher efficiency and lower pressure drop allowing air-handling systems to stay cleaner and more efficiently.
