The sintered porous element establishes a physical barrier, allowing the passage of a fluid (liquid or gas), without the passage of particles. The retained particle size is defined by the filter opening (poro size).

In bubbling, or sparging, a gas is injected into a liquid, through the porous element. The bubbles generates turbulence and/or dissolves the gas into the liquid. It is used in the carbonation of beverages, in fermentation processes and in flotation operations.

The porous element allows the passage of fluid, gas or liquid, retaining solid particles (catalysts) or even other fluids (oil). Backwash operations, with inversion in the direction of the fluid, allow the filter to be cleaned or recovered.

The porous element acts as media for the gas injection, creating turbulence that fluidizes a particulate product, such as, for example, beans and coal. This process is carried out in reactors or cameras so called “fluidized bed”.

The porous element attenuates an undesirable noise – electrical panels and compressors – without compromising the “shielding” of this equipment. It can also to protect sensors.
