Technical Specs


SILOTOP® polyTUBE™ venting filter is made of stainless-steel housing contains vertically mounted polyTUBE™ filter elements.
polyTUBE™ filtration technology ensures high filtration efficiency thanks to ZERO™ nano-fibre media and open-profile tubular cell structure for reduced dust residue and high performance over time.
Silo Venting Filters


The SILOTOP® polyTUBE™ venting filter is designed to work in applications with discontinuous operation.
The venting filter must let air pass through but retain dust, and this mechanism must last as long as possible.
The dust that is separated from the air flow through the polyTUBE™ filter elements is recovered in the silo thanks to the integrated automatic cleaning system that is controlled by a proper control unit (FILMEC™) and operates both during and at the end of filter operation to keep it efficient over time.
