Filter Media In Rail Transit，hot-blast air fusion technology with elastic and tenacious fiber combed to form compact filter. Double sided spray and secondary flame retardant treatment, with better flexibility and strength, and better flame retardant effect, with better resistance to corrosion of all kind of solvent, acid base and high temperature.
● Low resistance
● High dust holding capacity
Mainly used for rail transit air/metro conditioning system, such as subway, train as well as bullet train.
1. Air intake filtration of the train.
2. Filter of air supply system in air conditioning of the train.
3. Secondary filtering in high-quality painting system and air intake system of baking equipment.
4. Can be customized in pad/pad with frame/roll.
