High temperature filters for the Hot Gas Filtration

One of our specialities are filters for applications where high temperatures can occur or are needed and clean process air is required like in the drying industry or power plants.


Based on the usage of high quality raw materials and through intensive research we could develop filter media, which have a higher temperature resistance than regular air filter media on the market. Which this approach we can manufacture polyester based material which can resist a peak temperature of 200°C. Our hot gas filters benefit from all our quality characteristics we implement into our coarse and fine filters. The fibre construction is not harmed by the hot process air and remains on the long term its filtration performance. Also is the filter media not being damaged by the hot particles which are being filtrated and protects your infrastructure from contamination, which can stove and cause damage. Through raising requirements of clean air regulations, new markets are created for this media from private households to industrial applications.
