Brief Introduction:

polyester needle felt adopt nonwoven workmanship, with the property of stable physical dimension,easy cake release,  good air permeability,wide used for industrial dust collector,prevent air pollution project . After wate-oil repelled treatment,can be use in the circumstance of moisture and oil mist for a long time.

Advantages:

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,gas densith can be greatly lower than the country the standard stipulation.

3.After heating,singeing and coating treatment,the surface should be smooth,difficult to stop up and out of shape ,easy for deducting and long using-life usually 1 to 5 times longer than mechanical filter cloth.

4.Extensive use and good chemical staility.It can filter gas both at normal atmospheric temperature and high-temperature including corroding gas mixed with acid and alkali,water and oil.Needle-punched felt are widely used in metallurgy,chemical industry ,building materials,smelting,generating electricity ,pottery,machinery,mining,petroleum, dyestuffs,food,grain processing ,etc.

It is an ideal medium to separate liquid from solid and ideal material to purrify and filter gas.
