Silencer
All the turbines used in the central vacuum systems
Disan are silenced with soundproofing materials at
the end of the suction and of the delivery, in order
to maintain a sound level lower than the levels
previewed by the regulations.
The models DS Super Compact are equipped with
an additional silencer, mounted on the internal part
of the central unit.
Optional silencer are available in order to reduce
the noisiness produced by the motors. The silencer
must be mounted on the end of the breather pipe
(with whichever inclination), in order to allow the
absorption of all the noises produced in the piping.
The zinc-coated silencer is available in the following
models, to be chosen on the basis of the diameter
used on the breather pipe.
• Zinc-coated silencer diam. 70/63 mm complete
with 2 zinc-coated couplings Code IS10
• Zinc-coated silencer diam. 100 mm complete with
2 zinc-coated couplings Code IS11

Central vacuum systems
Particular requirements
of planning
In the case in which the piping crosses structures
where there are dilatation joints or it connects 2
different structures use the following items:
•
Dilatation joint in order to give flexibility to the
piping
•
Covering in thermal insulating material (normally
used in the hydraulic field) to avoid condensate
problems and to give flexibility to the piping in
the case of settlings of the building or of the
ground.
In the case that the pipe line crosses the fire barrier
structure, plan the special collars for wall or floor.
Wall: 2 collars (one for every side)
Floor: 1 collar on the lower side
Dilatation joint Ø 50 mm code VR056
Dilatation joint Ø 63 mm code VR064
Dilatation joint Ø 80 mm code VR084
Dilatation joint Ø 100 mm code VR104
! WARNING !
Do not install external piping in contact with
sunbeams and atmospheric agents. In these cases
we advise to use zinc-coated stainless steel tubes.
Contact the technical office Disan.
If it is not possible to avoid the installation of external
tubes, cover the tube with thermal insulating material
(normally used in the hydraulic field).
If the piping is installed externally to the building
and underground, plan a container barrier.
