Installed up to the concrete or directly on the metal hopper of the silos.
The cone is formed by bolted and welded metal sheet frames specially bent.
Thanks to a centrifugal fan connected through a duct to the body sheet of the silo, the air is pushed inside through a pipe connected from the body sheet of the silo directly to the cone where after the equipoise of the pressure, the air is distributed in the silo.
The support of the system is achieved with footings and plugs in the concrete cone of the silo.
