Inpro/Seal Air Mizer seals are permanent shaft seals for powders, liquids, slurries and bulk solids on industrial processing equipment, preventing product loss, harmful emissions and contamination. Due to their non-wearing design, Air Mizer shaft seals are maintenance-free and constructed to last the lifetime of your equipment...The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills to the furnace area.
