Filtration Products Suitable for High Temperature Applications Within numerous applications there may be a need for a filter that can withstand high temperatures. Typically this is the case when filters are being used for air sampling with acidic gases, stacks, flues and aerosols. The most common filter material for these applications are Quartz Fiber Filters. Quartz Fiber Filters Quartz Fiber Filters can withstand temperatures up to 900 Degrees C, proving them to have a higher resistance than glass microfiber filters which are also commonly used in high temperature applications. These filters are heat treated to reduce trace organics, and come binder-free. Their ability to pass large volumes of air at effective rates make them a superb choice for air monitoring, sampling and PM10 analysis. Quartz filters also reflect very low metal content, and superior chemical purity.

They can withstand temperatures between 180 – 500 Degrees C, and prove to have very efficient flow rates along with a high loading capacity. Although an option for high temperature filtration, Glass Fiber Filters are offered in various grades determined by pore size and they can be suitable for a multitude of laboratory applications. They can also be supplied with a binder, or binder free.
