Lightweight Faber diving apparatus with bridge valve 12544-RE and stand Cylinder body approx. 10.5 kg - diameter 171 mm - length approx. 58 cm Max operating pressure 200 bar No more painting, no protective nets required! The cylinders, made of highly tempered steel, are immersed in a liquid, hot zinc bath with a great deal of expertise. The zinc forms a strong metallurgical bond with the steel and protects the cylinders from external corrosion better than any other external treatment. Painting is unnecessary. When new, the “Steel Beast” cylinders are shiny silver/gray with various color nuances and a visually irregular surface structure. The cylinders become darker and duller after a short time.
