Product quality and compliance with dust emission limits are core requirements for dedusting in the cement, gypsum, and lime industry. The choice of filter media is of paramount importance in cement kilns where there are high NOx levels due to high combustion temperatures. The Everspring filter media range offers for each process in the cement, gypsum, and lime industry technically sophisticated solutions.
