PURAFIL ES, is made from alumina in spherical pellets, purple in colour due to the presence of potassium permanganate.

PURAFIL may be used in any type of filter for horticultural-floricultural product storage (kiwifruit, cut flowers, vegetables etc)
Ethylene and other harmful gases such as hydrocarbons or SO2, are oxidized.

PURAFIL ES ensures complete and continuous depuration in the storage cells.
Due to its high porosity, the product remains active until complete saturation.
Each production batch, realized using ISO 9001 certified techniques, is controlled on the following parameters: size, humidity, crush strength, abrasion resistance, ethylene absorption capacity and specific weight.
