Fabric SiloSac Alare

Our fabric SiloSac Alare features a robust galvanised or stainless-steel structure ideal for use in any internal environmental conditions. SiloSacs Alare are designed and made to measure based on the available space and customer needs.


Simplicity, speed of assembly and safety. The SiloSac Alare is produced and marketed exclusively by Silos & Silos.

Fabric SiloSac Alare

The body of the bag is made of antistatic Trevira fabric which ensures uniform emptying of the product by gravity. This fabric has flame-retardant properties that do not degrade with use, washing, or the passage of time. Another advantage of this fabric is the ability to block the microbial development of odours and to inhibit bacterial growth in its fibre, thanks to an additive with a permanent antimicrobial effect.

The top is made of antistatic filtering fabric which allows the evacuation of clean air during the silo loading phase from the tanker.

The big bag is made with a patent pending wing brace (Patent no. 202019000001428). The wing bag has an open brace and a system to anchor it 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 traditional brace, on the other hand, has the classic slot in which the horizontal beam must be inserted and the whole brace is mounted on the vertical beam.


  • Assembly in absolute safety and speed without inserting the horizontal beam in the braces.
  • Simple assembly and positioning of the structure and easy insertion of the big bag.
  • No need to disassemble and reassemble the structure to wash, sanitise or replace the big bag.
  • Solution also applicable to existing silo structures.

The SiloSac Alare is available in the Small version, with a variable capacity between 3-20m³, and in the Plus version, with a capacity between 20-100m³.
