Sintered felt filter bag is a porous filter bag for depth filtration. It is made of bundle metal fibers by sintering in high temperature and welding after special non-woven laying and stacking with the pore gradient formed by layers of different pore sizes. Our filter media are composed of a metal cage skeleton, coarse metal fiber layer and fine metal fiber layer. It is widely used in various industries involving high temperature flue gas dust removal due to its excellent resistant to high temperature and corrosion.

Filters are generally provided with a flange for connection to enhance its high temperature and high pressure resistance.
Flange plate
Flange structure plan
Flange & seal gasket installation
The filter is sealed by tightly compressing the seal gasket onto the back of the flange to the upper surface of the installation plate. The roughness of the upper surface of the installation plate and the fitting surface of the flange shall be well designed to perfectly match with the chosen seal gasket as it directly determines whether the seal is reliable and leek-free.
Metal seal gasket
Semi-metallic seal gasket
Asbestos rubber seal gasket
PTFE seal gasket
Hold down bars are the seal fittings between flange holes and the installation plate for fixing. Both parallel and cross hold down bars are available for your option.
Parallel hold down bars
Cross hold-down bars
