Y5-47 series fan has a lower noise compared with previous Y5-47 because of a series of improvements, in order to meet the requirement of supporting boiler, 4D, 5D, 6D, 7D, 10D, 11D, 12D, 12.4D these eight models were newly added. They are suitable for various burning coal and industrial boiler equipped with smoke-eliminated and dust-removed device. All can be adopted when the inlet condition are suitable, performance adaptable with max temperature not exceed 200â??.
