Silicone Weighing Bellow Asymmetrical Conical

Silicone Weighing Bellows Asymmetrical Conical have the added advantage of the asymmetrical design, the angle of the bottom cone is on a 60° angle, which prevents powder collection, piling or blockage inside the bellow shape.

No powders can remain within the bellow shape, which is possible with the conventional spherical bellow. These bellows are suitable for contact with foodstuffs.

Silicone Weighing Bellow Conductive

Silicone Weighing Bellow Conductive are made of a silicone compound to which carbon has been added to make the silicone compound electrostatically dissipative and have a resistance lower than <10^6 Oh. The low electrostatic resistance means light powders do not tend to stick on the surface of the bellow, and electrostatic energy is not able to build up on the surface of the bellow, therefor not creating any explosion hazards which may occur at high capacity powder flow rates and high air speeds.
