1. High hole rate and good air permeability.2,High efficiency of cleaning and low density of gas.Extensive use

 Non-woven fabric needle felt

 Many advantages of product

1. High hole rate and good air permeability can increase the loading ability of the equipment and reduce loss and energy consumption.

2,High efficiency of cleaning and low density of gas. 

3,After heating, singeing and coating treatment, the surface should be smooth, difficult to stop up and out of shape, easily-dedusting and long using-life usually 1 to 5 times longer than mechanical filter cloth. 
 
4,Extensive use and good chemical stability. It can filter normal atmospheric temperature or high-temperature gas including corroding gas mixed with acid and alkali, water, oil.  

 5,The working temperature of Dacron needle-punching felt is under 150°C when in smoke dust occasion.
