Specifications

DALON bronze sintered filter disc and porous components are sintered parts with high porosity, between 30 and 80% in volume, currently made of Bronze or Stainless Steel 316L and PE/PP material, also new invented with sintered Active Carbon material.

Particular Characteristics:

– The mean pore pitch is variable, from 1 µm to 250 µm.
– They are depth filters which efficiency is very high.
– Work at high temperature and high pressure without deformation.
– The chemical resistance is good
– Filter can be weld and machine after final shape, so they can be adapted to specific assembling purpose.
– DALON sintered stainless steel filter element can make its cleaning easy, so they are reusable.

Range of filters and sintered porous components:

– Filters and porous components . They are made of spherical particles of powder. Filter element could be offered by small wall thickness and high length, made by isostatic compacting. They are used as cartridge filters for high flow.
– Filtering Elements, with different shape as diameter from 2 to 250 mm, and length from 2 to 1500 mm.
– Sintered Silencers, , Sintered bronze porous material with the thread integrated in the silencer.

The elevated micrometric porosity of these components is useful for many applications:

– Filtration of fluids. Porosity is able to retain the solid particles contained in a liquid or gaseous fluid, and also to separate liquid and solid phases. The application sectors are: automotive, marine, aeronautical, rail, industrial machinery, household appliances, heating, water depuration, food industry, chemical and nuclear industry, packaging manufacturing, tobacco pipes and electronic cigarettes, etc.

– Pressure drop. Porosity decreases the pressure of the fluid that circulates through it. Different applications are: pressure control in pneumatic and hydraulic circuits (compensators, drainers, regulators), noise absorption of gas piping (Silencers), pneumatic cylinders, sensors and manometers protection, gearboxes, etc.

– Flow control. The isotropic and homogeneous porosity allows that a fluid that circulates through it have a constant flow at the exit of the porous part. Typical applications are heat exchangers, medical gases, scuba diving, industrial gases, etc.

– Aeration. The air circulation through porosity results in a constant and controlled air flow at the exit of the porous component. The use sectors are: liquids repassing in food industry (liqueurs, wines, and gas beverages), ionization, gas burners, aquaria, clinical analysis, etc.

– Fluidization. The air circulation through the porous component has as result that the exit flow is distributed with the same pressure in all points, allowing then the controlled handling of powdered products. This property is used for: transporting cement, flour, alumina, ashes, toner powder, etc.

– Anti-moisture. Porosity is able to retain and condense the moisture contained in a gas that circles through it. Typical applications are: drying in general, electronic equipment’s protection, etc.

– Flame protection. Presence of a porous component before a flame avoids accidents in case of flame return. Typical applications are: gas burners, heaters, welding facilities, etc.

1.RAW MATERIAL / MIXING

Sinter powders can be of pure metal  or plastic powders ;Active Carbon powder mixed depending on the composition of the final material filtring degree.

2.TOOLING/COMPACTING

The powder mixture is compacted inside the tooling, which has the negative shape of the final part. The tool is an element of a very high precision, and high durability. 

3.SINTERING/INSPECTION

Sintering in continuous furnaces, under controlled speed and at an atmosphere with controlled chemical composition by temperatures between 750 and 1300°C depending on the material 

DALON ALSO OFFER SINTERED SLIDING BUSHING / SILENCERS:
