To visit a fair falls under doing business, if it is part of your job, when being sent over by a foreign company. Specially if you want to do negotiations or even sign contracts. So you would need a business visa.
If the fair you are visiting is an industrial fair such as for machinery or trade, you will need a business visa.
However, there is conflicting information for this. This russian company claims that as long as your trip fits into the time needed for a tourist visa, you can get one no matter what the purpose of your trip is.
I would recommend contacting your local Russian embassy or consulate and simply ask them.
