Modern ventilators are a bit like an air compressor. Air enters one side, exits the other at higher pressure. There is no place for the virus to accumulate. The contaminated air will just be dumped in the room. There are virus filters (HEPA) which you can attach to the tubing so that the virus is caught there.
