It is possible to protect your products or the products of your customers from a high concentration of ethylene gas. This can be done using this very narrow freight tube of only 10 cm wide. Within a few seconds you can attach it to the ceiling. This is made possible by the very strong fix-twists, which are included. Oxylene is a powerful and environmentally friendly ethylene filter. The air flows easily through the round grain. This is necessary for the optimal functioning of Oxylene. The grain is a hard product which does not crumble. There is no aluminum grit that may come between your products. The grain had a purple color. As the ethylene has been processed, it's color changes to brown. The residue is brown stone.
