Filter Media In Rail Transit / Metro Air Conditioning System Corrosion Resistant High Temperature Resistant​

Application

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. Can be customized in pad/pad with frame/roll

Material & Features

1. Hot blast air fusion technology with elastic and tenacious fiber combed to formcompact fiter.

2. Double -sided spray and secondary flame retardant treatment, with better fexility and strength, and better flame retardant efect.
3. With better resistance to orrosion, all kind of sobvent, acid base and high temperature.

The application of air filter media(cotton) is very wide, Air filter media or mesh, is normally made of Polyester fiber or (abbr. as PET), PET is made by polyethylene glycol terephthalate, or synthetic fibre/ polyester fibre , with excellent wrinkle resistance, flexibility and dimensional stability. The material offers excellent insulativity , light resistance, wear resistance and humanity resistance, chemical-wise, with perfect chemical reaction resistance, weak acid and weak alkali resistance.

Many Industrial products must be produced in a clean room atmosphere. such as surface treatment, spraying, electronic, optical electron, pharmacy, food, air cooling industries. All those fabrication process will need airflow however no dust is allowed, therefore air filters must be deployed to filter all the dust to keep dustless airflow to meet manufacture air quality standard. The filter ffiency is decided by the porosity of the filter material, technically, if the porosity is sufficiently small more dust/particles will be arrested within the filter material.

The primary filter media is intended for new air fitration, to filter particles < 5 m with big dust holding capacity but limited windage, cost effective and inexpensive, The medium filter media is applied in spraying industries with ability to filter particles in between 1~ 10u m, the filte products designed for spraying heads to improve the spray paint room air quality.

High temperature resistant and flame retardant fiber glass are made of heat resistant/fire retardant material and mostly used in high temperature working condition.

According to Chinese filter grade (GB/T14295) also EU standards, from primary/medium/Hepa filter are ranked fromG1, G2 G3, G4, F5, F6, F7 and F8.
