Everything You Need to Know About Fans and Ventilation



Ventilation inside your building should be an important aspect of any business; especially regarding hospitals, schools, commercial warehouses, restaurants, apartments, and municipal buildings. Having quality equipment can help your business properly ventilate, as well as save money on heating and air conditioning costs down the line. Here are a few important things to keep in mind when thinking about ventilating buildings, individual rooms, bathrooms, kitchens, and other ventilation needs.


  • Take the volume of the room and divide it by five to find the minimum size bathroom fantech exhaust fan you’ll need.
  • Additional venting may be needed if bathroom ceilings are over eight feet tall.
  • Sone rating indicates the amount of noise a bathroom exhaust fan will make. Sone ratings range from 0.5, which is barely audible, to four, which is very loud.


  • Restaurant exhaust systems are typically cleaned once every three months but they should be cleaned more often.
  • Installing efficient fantech motors in walk-in freezers has been shown to save around $200 a year per fan.
  • Electronically cummutated fans are the most efficient for freezers.


  • Laminar fantech exhaust fans are a popular option for hospitals due to their circulation rate of 300 times per hour.
  • There are various safety and health criteria requirements for ventilation in hospitals.
  • Outside air must be clean to be able to successfully ventilate hospitals.


  • Demand ventilation controls can be installed on new or existing hoods.
  • Reduce the cost of operating an exhaust system with demand ventilation controls. They have shown to reduce up to 50% of the cost.
  • Backing off by only three degrees on central cooling could lower air conditioning costs by up to 15%.
  • Roof-mounted utility fans usually have the inlet and outlet 90 degrees from each other. They are typically used in areas of high-static pressure losses.
