Summary – Part I
It is about:
Ratio between purchase price vs. installation cost
Lifetime of the fabric
Reduced downtime
August 18th 2011 © Mühlen Sohn Slide 7
What makes the difference? – Part I
The Raw Material
Highest abrasion resistance
through
a smooth surface
that is
less sensitive to wear
gives you the
longest lifetime

Abrasion test today
Summary:
Abrasion figures are means of measuring the durability of a fabric and they allow comparisons of the
relative life expectancy of various products.
According to the test resulte and the feedback from our world-wide customers you are able to
achieve up to 3 times longer lifetime by using Fluitex airslide fabrics.

Examples – Silo Applications
It is about:
Permanent availability
High risk in case of failures in the discharge system
(uneven discharge can result in damages in the silo
walls)
High cost associated in case the silo would not
empty
If applicable, government regulations for recurring
inspections
August 18th 2011 © Mühlen Sohn Slide 11
Minimize risk through the right fabric
Having problems with your airslide dust
collector?
Do you see complete discharge of your silo?
Do you have the feeling, that your airslide is
working inefficiently?
August 18th 2011 © Mühlen Sohn Slide 12
What makes the difference?
The Production Equipment
Even aeration and flow of cement
is a result of the
same amount of air over the whole surface area
achieved by
low and uniform pressure drop in the fabric
and gives you
the most efficient material flow
August 18th 2011 © Mühlen Sohn Slide 13
Production Equipment
Precision through laser
cutting technology
In-house engineered weaving
machines
August 18th 2011 © Mühlen Sohn Slide 14
