Sintered materials of POROUS PLASTIC FILTERS offer a self-supporting structure with high mechanical strength. DALON manufacture various filter grades with specified pore sizes of POROUS PLASTIC FILTERS and flow rates in order to have the appropriate solution for your requirements.


Application Examples

●Aeration: The POROUS PLASTIC 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 POROUS PLASTIC 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.

Porous Plastic Filters Properties and application examples

DALON Porous Plastic Filters could be used with air powered tools, valves, and cylinders to reduce noise and filtering exhaust fumes.

For purpose of reduce noise, filtration, and flow ratings , please selecting DALON mufflers, breather vents, and filters in below ways:

1) Noise Measured in decibels (dB), the rating indicates how much Filters reduces exhaust noise from your tool or equipment. Usually recommends hearing protection for exposure higher than 80 dB.

2) Filtration: Filters trap particles to clean the air exhausting to the environment or going into your equipment. The size of particles is measured in microns; the lower the number of microns, the smaller the particles that are removed from the air.

3) Flow—Measured in standard cubic meter per minute, this rating is the maximum air flow that a product can withstand.


Sintered PE Porous Filter


Please Note to choose the correct pipe size, measure the threaded inside diameter (ID) or outside diameter (OD) of your pipe or valve, usually DALON can offer filter types in standard threading from 1/8 to 1 inch. Filters with pipe connections thread into NPT or metric threaded exhau.
