The FS D40 16 10 4000 KSV V2A air terminal is a high-quality lightning protection element for the safe protection of roof-mounted structures, such as antennas, ventilation systems, or other metallic constructions. It is directly attached to pipe structures with a diameter of 40 mm and features a tapered rod with a diameter of 16 mm at the connection point and 10 mm at the free end, ensuring optimal dissipation of lightning currents. The total length is 4000 mm, with a maximum free length of the air terminal being 3500 mm. The clamping and securing length of 500 mm allows for flexible and secure installation on various structures. The product is made of stainless steel (V2A), ensuring high corrosion resistance and durability even in demanding environments. Included is an earthing connection with a KS connector made of NIRO, designed for connecting round wires with a diameter of 6 to 10 mm. The air terminal complies with the standard EN 62561-(1+2) and is therefore suitable for use in professional lightning protection systems. With two mounting points, it ensures stable and reliable installation.
