Foam filter media
10 mm | willpore D series pinta filtration

willpore D filters are made of reticulated foam impregnated with active carbon powder or granulates. It has been developed to treat high concentration of odours, organic vapours as well as ozone.

Description

Reticulated foam is the perfect medium to support active carbon powder or granulates. Thanks to its controlled porosity, added active carbon is easily in contact with any substance to be treated and provides willpore D a very high adsorption efficiency with a low pressure drop. Desired efficiency as well as pressure drop of willpore D filters can be tuned in our process by changing the porosity of foam and carbon type.
Foam characteristics

Foams used are especially dedicated to filtration thanks to a reticulation process that gives to this medium a controlled porosity (from SPPI 10 to SPPI 20). Adjusting this parameter, pinta filtration is able to manage pressure drop as well as efficiency.

The following graph represents the impact of porosity on pressure drop (data given for a same carbon & weight, airflow of 90m3/h).
