What is High Temperature Fiberglass Filter Media?

High-temperature fiberglass filter media is based on ordinary glass filter media raw materials, and some special high temperature resistant materials are added to improve their high temperature resistance. It is designed to withstand and operate effectively in high-temperature environments while providing efficient filtration. It is commonly used in industrial air filtration systems, especially where elevated temperatures are encountered, such as in power plants, steel mills, cement kilns, incinerators, and other high-heat industrial processes.

Flame Retardant Performance and Safety Fiberglass Filter Media

At RT AIR FILTERS, we are aware of our corporate responsibility in environmental protection. Therefore, we are committed to practising sustainable development throughout the entire production cycle of our fiberglass filter media.

High temperature glass fiber cotton can withstand operating temperatures of up to 300 °C, and even up to 500 °C in a short time, without deformation or shrinkage at high temperatures. It also has good fire resistance and meets Class A fire protection standards

Choosing RT AIR FILTERS' fiberglass air filter media means you are choosing to work with a company that is committed to green production and sustainable development.

Fiberglass Filter Media VS High Temperature Fiberglass Filter Media

Ordinary glass fiber is melted by glass beads, and then dried and cured. It has a certain temperature resistance, and high temperature glass fiber is on this basis, plus flame retardants and other substances to make it able to withstand higher temperatures.
Of course, fiberglass filter media will be cheaper than the heat-resistant one, which is more affordable and common. And the life of high temperature resistance will be longer.

QUESTIONS AND ANSWERS

Q1: Can You Cut Flat Before Rolling Up On The Paint Stop Filters?

A1: Most Of The Paint Stop Filters On The Market Are Cut Flat After Rolling Up Because It Is Very Easy Operate, There Will Be A Problem That The Edge Is Not Flat. Certainly, We Can Cut Flat Before Rolling Up, Which Can Be Up To 2.6m Wide.



Q2: How Did You Pack HEPA Filter?

A2: One Unit Is Packed With PE Bag Put In 5-layer Carton. If The Customer Is Worried About The Transportation Process, We Can According To The Requirements Of The Form Of Beating Bracket + Corner Protection + Wrapping Film Packing.

Q3: Have HEPA Filter Passed The DOP/PAO Leak Test?

A3: Sure, Our HEPA Filter Is 100% Able To Pass The PAO Test. Because We Will Do An Integrity Test Of Each HEPA Filter For Efficiency And Leakage Before Shipment And Provide A Corresponding Test Report. Any Leakage Will Be Regarded As Unqualified Products And Reworked. We Are Using MPPS Scan Test For HEPA Filter Integrity Test Which According To EN 1822 Standard.

The Scanning Tracks Will Cover The Area:

Inside Filter Material, Sealant, Filter Frame, Corners, Gasket, Seal Of The Filter Mounting Assembly, The Sealant Between Filter Frame And The Gasket


Q4: How Long Does It Usually Take For Me To Receive The Goods?

A4: Depends On Whether You Want To Do Customization Your Air Filters Or Not, And Depends On The Speed Of Customs Clearance And Logistics, But We Can Guarantee To Ship Regular Air Filter In Less Than 7-10 Business Days, And We Have Customers In Singapore Who Received The Goods In Less Than 2 Weeks After We Ship Out.
