SiloSac in Trevira fabric

Our fabric SiloSacs consist of sturdy galvanised or stainless-steel structures and a Trevira antistatic fabric containment bag. This type of solution is highly customisable and makes the SiloSac suitable for any indoor environment.


The square shape and the big bag body made of antistatic Trevira fabric ensure uniform emptying of the product.

SiloSac in Trevira fabric

We can supply a big bag with a standard brace or a wing brace with Silos & Silos patent. The big bag with standard brace has the classic slot or collar into which the crossbar must be inserted and then the whole structure is mounted on the vertical beam. The wing bag, on the other hand, has an open brace and an anchoring system to the wrapped brace structure, with an aluminium and steel retaining insert. This makes it easier to assemble and also to replace the big bag where necessary.

The upper part of the SiloSac is made with antistatic filtering fabric to allow an air vent during loading of the silo while the containment bag is anchored to the structure with braces, sewn on the external part of the fabric.

A vibrating bottom, with internal counter-cone, is connected to the silo, ensuring a uniform unloading of the product by gravity.

The structure is designed to be easy to assemble and transport and is suitable for indoor environments.

The silo can be equipped with a porthole that allows a visual inspection inside for the preservation of its hygienic conditions and practical maintenance.

Trevira fabric is suitable for containing food products according to Italian standards (Ministerial Decree of 03/21/73) and American standards, dictated by the “Food and Drug Administration (FDA)” (Cap. 1 Par. 177-1630). This fabric is easily washable in industrial laundries using only water, or by washing on site with the appropriate equipment and operator.

The fabric SiloSac is available in the Small version with variable capacity between 3 – 20m³ and in the Plus version with capacity between 20 – 100m³.
