The nonwoven filter media is made up of layers with different fibre fabric and having the high filtration efficiency, The fibre fabric gradually trend to thin and dense from Layer of gas entrance to the Layer of gas exit. The filter function was completed by filter effect of different fibre layer and fibre surface. it has the excellent air permeability and good strength after special process. The water resistance and dust storage is 3-5 times thanfilter paper .It widely use in automotive filter and other air filter.
Special Characteristic:
1).Initial efficiency í¦97.5% ; Final efficiency í¦99.8%
2).Excellent air permeability and enough micromesh with good dust-saving ability.
3).Easy taking shape and eximious strength capability
Chuck gauge; 10cm

The air filter paper is made of full wood-pulp, have high air permeability, high filter function, excellent bursting strength and toughness.
Silicon crystal growing furnace
Silicon crystal growing furnace for solar cell, using graphite heater, melt poly silicon in inert gases. Thun using vertical pulling method to produce high qulity single crystal silicon for solar cell and other electronic products. The system using 18 quartz crucible with 70kg melt stock or 20 quartz crucible with 100kg melt stock produces 6 or 8 single crystal silicon
