Abstract
The fan assembly provided with a fan ring, including a first leg and a second leg, may be arranged with a shroud that may include a first sidewall, a second sidewall, a third sidewall, a first ring, a second ring, and a third ring. An air passage may be formed between a distal end of the first leg and the third ring, the second ring and the first leg, the second leg and the second sidewall, and a distal end of the first leg and the first ring. The air passage may be configured to improve acoustic performance and air flow efficiency.
