Edge-Seal Mounting Support for Diesel Particulate Filters (.pdf)
Due to the large sizes, high bulk densities and high thernal expansion coefficients of diesal particulate filter (DPF) substrates, conventional mounting systems fail to provide sufficient mounting pressures. L-Seal mounting supports used in DPF applications not only provide these forces but also

wire mesh may filter to as fine as 25 ∝m absolute, and resin-impregnated paper (disposable) will filter to around 30 ∝m absolute. If silt control is the required function, special filters that are capable of 1 to 5-∝m absolute filtration are necessary. Unlike the various metal chip-control filters
