DALON manufacturer of porous sintered filters since 2002, offers a variety of solutions to meet our customer requirements.
Our sintered filter elements are applied in sparging, sensor protection, gas and liquid filtration, dampening, bulk handling and etc.
which for solution of corrosive and high temperature environments.
DALON filter made of stainless steels, bronze, plastic, which can be manufactured up to 1,000 mm length and 250 mm O.D.
Larger elements also can be assembled by welding procedure. DALON sintered filters have an excellent back flush performance.
The filter grades down to 0.5micron and up to range of 250micron.

DALON sintered filters Application Examples:
•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 DALON sintered filters 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: DALON sintered filters 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 DALON sintered filters 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 DALON sintered filters air circulation through porosity results in a constant and controlled air flow at the exit of the porous component. The use sectors are: liquids re-passing in food industry (liqueurs, wines, and gas beverages), ionization, gas burners, aquaria, clinical analysis, etc.
•Fluidization: The DALON sintered filters 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: DALON sintered filters 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:DALON sintered filters Presence of a porous component before a flame avoids accidents in case of flame return. Typical applications are: gas burners, heaters, welding facilities, etc.
