Central Vacuum Systems

It is possible to divide a central vacuum cleaning system into four main components:

- PVC-tubing
   usually chased into wall and underground

- Inlet sockets
  placed on the wall or on the floor

- Central vacuum cleaner
  fixed to wall permanently

- Cleaning tools
  available in kits or separately

To each inlet socket, ideally positioned inside all the inhabited rooms (including cellar, stairs, garage, terrace, etc.), you connect a light and flexible tube, through which you reach every corner of the house. On its final handle you apply a suitable brush, for every kind of surface to clean. These vacuum brushes are similar to those you apply on the traditional vacuum cleaners, but more sophisticated and much stronger, because you have a very increased vacuum power.

The tubing in polyvinyl chloride for domestic applications is piped in always with a diameter of 50 mm. The choice of the material is essential in order to assure a rapid air-current without hindrances inside the tube. Also the connection fittings must be absolutely airtight and cold-welded with the proper glue.

The central vacuum cleaning system is positioned in a secondary room and can be started in different ways:

- By the on/off switch on the handle of the flexible hose
- By introducing the flexible hose into the inlet socket
- By a built-in micro switch on the inlet socket
- By a remote control device


On/off switch on the handle


It is considered as the most comfortable and safest system to start the vacuum process.
Like the other electrical starting-circuits it makes use of low tension current and, as a consequence, it is absolutely harmless for people and animals.


Introduction of the flexible hose into the inlet socket
The handle of the flexible tube has a sheathing, which, introduced into the socket, closes the two contacts positioned inside of it. As a consequence, the central unit starts.

Remote control device
This alternative of starting by remote control device is advisable for special applications or in case it is not possible to apply one of the other solutions, because of the absence of electrical cables.

The air drawn in through the tube-system and conducted to the central vacuum cleaner rides at ca. 100 km/h (~63 mph). At its arrival in the vacuum cleaner, through a special cyclonical structure, you get a first mechanical-gravitational filtering of the air-dust mixture.

Only after this first separation, the air goes through a DISAN large cartridge filter, from 5400 cm² up to 20.000 cm² (830-3,080 sq inch), which draws up even the smallest particles.

According to the model, there are also other systems of air-conveying and supplementary protections, which prolong the life of the cartridge. We have also a supplemental cyclone for the dust-sedimentation in the plastic collecting-bag.

After this careful filtering-process there are still microscopical particles, which are able to pass through every kind of filter, remaining in the filtered air, and these are driven out of the house. Dust and dirt are banned definitively, far away from your lungs!
