Is there a cooler (computer-type fan) of a closed type?

Question

Do it yourself

Is there a cooler (computer-type fan) of a closed type? Well, so that there is no access to the internal parts of the engine, for what? I want to make a mini vacuum cleaner for collecting toner from a cartridge, from a fan bottle and hoses.

Answer 1

It is absolutely unsafe to collect toner with a vacuum cleaner. Toner particles are so small that they easily penetrate a cloth filter and are sent flying around the room, settling on all surfaces and in the lungs of everyone in the room.
Cartridges can only be refilled in a specially equipped room using personal protective equipment.

Answer 2

And what prevents you from buying a vacuum cleaner for toner initially, like this 3M: www.ink-market.ru/catalog/item/detail/34215.html

Answer 3

From an open elementary one can make a closed one .
Just keep in mind - they are frail and will not work with a filter. Unless - to blow dust-toner immediately into the street or somewhere else.

Answer 4

Find a better USSR vacuum cleaner and add a box to it (toner filter). it will be more efficient than crafting from a cooler, etc. details.
