Internal Venting Vs. External Venting

Upon purchasing various kinds of kitchen appliances, many do not give much attention to range hoods as much as they do to other kitchen appliances. However, whether it be the kitchen design or the performance, you can easily see a significant difference between a kitchen with a range hood and a kitchen without one. As any professional chef can tell you, cooking without a range hood may be very exhausting.

A range hood is a device that contains a mechanical fan that hangs above the stove or cooktop in the kitchen. Its main function is to remove airborne grease, combustion products, fumes, smoke, odors, heat, and steam from the air by evacuating the air and filtration. Through years of innovation, range hood manufacturers developed multiple types of range hoods that have different designs and functions. The staple range hood designs are known as under-cabinet range hoods, wall-mounted range hoods, island or ceiling mounted range hoods etc. Range hoods can have either internal or external blower, or both to carry out the job with different CFM. CFM is a way of calculating how many cubic feet of air are exhausted by the blower in one minute.

Just to summarize the overall advantages of having a range hood

  • Benefits your health by creating a safe environment with a clean air
  • Provides cooking and living comfort
  • Improves your property value by preventing the need for daily clean-ups
  • Better kitchen lighting due to the Halogen lights that are embedded at the bottom of the range hoods
  • Removes excess heat from you kitchen

A Range Hood with an Internal Blower

The internal blower is also known as recirculation, and it is typically known as a less expensive hood. However, internal blowers provide exceptional performance and comfortable sound levels just like other blowers. It is usually vented through the roof or wall, with the goal of minimizing the duct length. They are located within the hood structure, so only a single electrical connection is required. In addition to that, you will have the hood, blower motor, filters, fan controls and lighting all in one box. There are many benefits to having an internal blower. However, there are also some downsides to it. Internal blowers are easily accessible and very easy to install. Even though it produces a high level of noise, it is very functional and offers great performance for a long period of time.

External Blowers also do a great job at cleaning the air and keeping the kitchen clean and safe. External blowers can handle any experimental cooking that is performed with any type of range. They provide all the benefits of a having range hood at home just like an internal blower does, but instead of filtering the air and releasing it in the kitchen, external blowers release the air outside. It is usually vented through the roof or wall, with the goal of minimizing sharp turns in the duct that can prevent airflow. When the exterior blower is installed on the roof with some great distance between your range and the blower, you can easily minimize the noise level. However, external ventilation is harder to install than the internal ventilation.
