The Iranians, who are in Pool E of the second round along with Pakistan, Japan, and India, downed their guests in three straight sets 25-18, 25-14, and 25-11 in Azadi Indoor Stadium in the Iranian capital.
The Iranian team had earlier won Afghanistan, Chinese Taipei and India in the first round of the tournament without losing a single set in the competitions.
Iran is scheduled to take on Japan this evening.
"We had a good performance against Pakistan and earned an easy victory against them. From now on, we have to think about Japan," Iran's Captain Alireza Nadi said.
The Asian tourney opened on September 21 in Tehran and will run until September 29, with 16 teams vying for the top place of Asian volleyball.
Iran, Japan, South Korea, China, Australia and Kazakhstan are the only six teams which have won the Asian crown in men's Volleyball thus far.
