Low noise fan:

Low noise tube fans are the most popular choice for ventilation purposes in small and medium size houses, bath rooms and kitchens as noiseless and cost effective alternative to traditional fans. These fans are very useful for inflow of fresh air to the room and expulsion of odors with minimal noise and less power consumption. The initial cost and maintenance cost of inline fans may vary but overall benefits and efficiency of these fans greatly surpasses traditional fans.
