I know there are. but as to the name of them. I can’t help. About 20 years ago my Dr. had a vacuum that was built in his office building. The tubing ran through the walls. It had an outlet in every room. They just plugged the hose into the outlet and that turned it on. When you undid the hose it shut of the vacuum. Anything that it picked up was blown (vented) outside through a outlet. The drawback was dirt, dust and small pieces of paper were expelled outside. If you were walking by you might get hit with a dust-ball or crayon. You might try a building supply store like Lowe’s, Home Depot, or Menards. An added note: They didn’t like it as the tubing would plug often
