It is designed for high speed paper making machine or special paper machine. 

　　Using contact drying and convection drying principle, the high temperature and high speed hot air vertically　blowing to the paper, making fast convection heat transfer with paper surface, air film on the interface is damaged or reduced the thickness, so that the large cylinder drying rate increases greatly, and greatly improve the machine output and reduce the energy consumption of tons of paper. 

　　Maximum working speed: 2200m/min; 

　　Heat medium type: steam type, electric auxiliary heat type, fuel gas type; 

　　According to the different heat source of Yankee hood ventilation system , the maximum air temperature can be up to 500 DEG C, the airflow speed can reach 160m/s.
