Poranit P5 Aqua is a very porous material made of aluminum with a purity of 99.6% (density: 1.83g / cm³). Poranit Sprudler are high-strength and give off an excellent bubble pattern. They are even valued and used by professionals as emitters of oxygen. Our air vents are corrosion-resistant. Biogenic adhesions are decomposed by heating for 15 minutes at 150 ° C and can easily be removed with a brush. The outflow is then germ-free again at the same time. It is not possible to apply ozone! P5 Aqua is available in all sizes up to 1,200 x 800 x 10-140 mm. You can order air vents and food insects online in our online shop at: www.hermetia-zucht.de.
