These filters are used for coarse filtration for removal of particles in range of 10 to 50 microns in the efficiency range of 80 – 95%. The output Air of pre filters is then passed to second stage i.e. fine filters and enhance the life of fine filter. Pre Filters are cleanable/ washable in nature to obtain longer life and having low pressure drop. These filters are very economical.
