The university library of Moscow exists since 1755.

The library contains 10 million books in different languages as well as very rare books and manuscripts.

Every year around 130.000 books are added to the collection.

For a library with this many books it is important that the air is clean and optimal for the books.

Thanks to the installed Disan central vacuum cleaners (two models DS D02 125 and two models F03 125) clean air is no problem.

Together with the central vacuum cleaner 750 inlet valves have been installed on which 4 operators are able to work simultaneously.
