Sava
PRODUCT DESCRIPTION
Sava is designed for air flow control and sound attenuation
in supply and exhaust air duct systems.
Sava is a perfect sound attenuator in cleaning doors where
it simultaneously can be used to control air flows in the
duct.
When Sava is used with terminal equipment use of pressure
reducing boxes can be generally avoided.
Sound attenuation and pressure reduction abilities of
exhaust valves are thereby improved decisively.
Sava has a specific air control wing which is used to regulate
the air flow in the duct.
The control wing has six basic adjustment positions, other
positions are available through downsizing the wing.
Sava is optimally shaped and sized which results in the
lowest pressure drop level possible of the product itself.
More efficient sound attenuation is easily achieved by
placing two Savas in the duct one after another.
MATERIAL
Sava is mainly fabricated of polyester that fulfills the
requirements of SBI test, a B class fire resistance test
(B, s1, d0) according to pr EN 13823.
Sava also contains slight amounts of foam plastic that is
corresponding to M1 emission standard regulations.
If fire is caught polyester and foam plastic are melt and
gasify. Smoke and toxicity test shows that the combustion
gases: does not release harmful quantities of toxic gases e.g.
carbon monoxide.

INSTALLATION
Sava has flexible product structure. If the terminal device
is removed, Sava can be placed behind 90° curve.
Sound attenuation and air flow control in the ducts can be
easily altered through terminal devices.
Sava stays inside the ducts because of friction and it can
be double-fastened e.g. with a screw.
Sava should be vacuumed or replaced when the duct
system is under maintenance.
