Porous Cups and Bushings

Porvair Filtration Group manufactures a wide range of cups and bushings for the process and industrial markets.

Porous sintered metal cups and bushings provide additional porous surface area for longer filter service life or for increased permeability when compared to porous sintered metal discs of the same diameter.

For the best pore size uniformity and quality, porous sintered cups and bushings are recommended when the length to diameter ratio is less than 3:1.

When the length to diameter ratio of a part is more than 3:1, then a porous sintered metal tube is the preferred option for the best pore size uniformity.
