Gas filter pinta filtration

willpore L

willpore L filters are made of reticulated foam impregnated with a liquid recipe based on active carbon powder. It has been developed to treat low concentration of odours, organic vapours, ozone even in air or in water.

willpore L is the combination of reticulated foam impregnated with a liquid recipe. Afterwards the obtained complex is dried in order to fix the different components of the recipe. Thanks to this process, we avoid particle loss. Furthermore, Willpore L technology gives the opportunity to add other properties to the final filter such as chemical catalyst or preservative.

Foam characteristics

Foams used are especially dedicated to filtration thanks to a reticulation process that gives to this medium a controlled porosity (from PPI 10 to PPI 25). Adjusting this parameter, pinta filtration is able to manage pressure drop as well as efficiency. For applications dedicated to water treatment, pinta filtration uses a dedicated foam resisting to hydrolysis, named TPPI (instead of SPPI for air treatment).
The following graph represents the impact of porosity between TPPI and SPPI on pressure drop (data given for a same carbon & weight, airflow of 90m3/h).
