Noise insulation: no forgetting the central vacuum system
With proper sound insulation, you can say goodbye to traffic noise, noisy neighbours and footfall from upper floors.

Preparation of the vacuum system
To determine the position of the vacuum inlets, the radius of action of the chosen hose must be considered.
- A standard 7 m pipe covers an area of approximately 35 m²;
- The pipe can be represented on the plan as a circle with a radius of 7 m (to the appropriate scale);
- The circles represent the actual surface coverage.
Useful information
- Avoid excessive overlapping of drawn circles;
- Choose to place inlets on internal walls rather than on perimeter walls (so as to make full use of the length of the hose). It is not necessary to provide 1 inlet point per room;
- By placing a vacuum inlets in the immediate vicinity of the stairs, it is possible to clean the stairs and any adjacent landings;
- Thanks to the special separators, water and ash can be extracted;
- The vacuum inlets can be placed at the same height as the switches or the electrical inlets.

How to set up the system
The information needed for correct design is essential and easy to use:
- Surface area and destination of the building where the system is to be installed;
- Number of simultaneous operators for each level;
- Selection of the length of the hose with which the cleaning will be carried out;
- Planimetry of the building;
- Location where the central vacuum unit will be installed.
With this information it is possible to proceed with the dimensioning of the pipe network, the positioning of the vacuum inlets and the choice of the central vacuum unit.

Pipe network sizing
The best performance of the system is achieved when the pipework is as short and regular as possible. In particular:
- If possible, the vertical riser should be constructed in a central position in the building;
- The pipes can be positioned either on the floor, on the wall or in the ceiling.
The diameters of the individual sections of the pipe network should be dimensioned in accordance with the following diagram:
- ø50 mm -> 1 operator
- ø63 mm -> 2 operators
- ø80 mm -> max. 4 operators simultaneously
- ø80 mm -> max. 6 operators simultaneously

Sizing for venting air extraction
In order to fully exploit the advantages of a central vacuum system, it is advisable to install a venting pipe to the outside, through which mites, dust and micro pollen not retained by the filter are expelled from the living environment.
If this drain is longer than 5 m, it must be laid with a pipe of a larger diameter than the one to the power station, in order to facilitate the outflow of air from the engine.

Indicative air flow values
N.B. these values may vary depending on the specific characteristics of the system to be built.
Pipe sizing and use
N.B. Max. operators with ø32 mm cleaning hoses, length 7m or 9 m.
