Tremendously beneficial in terms of giving you an idea of what type of ventilation system to install in your own home or office, knowledge of local exhaust ventilation design is the first step in shopping for a state-of-the-art ventilation system.

Components of local exhaust ventilation design

Before we go into the many different local exhaust ventilation designs, let us first take a look at the basic features that such devices share. The typical local ventilation system is usually comprised of the following parts:
  • a venting hood
  • an exhaust fan
  • one or more exterior ducts
Depending on the particular local exhaust ventilation design, there may be other components included. Nevertheless, no matter what the local exhaust ventilation design is, such devices perform the same basic function of drawing unclean air out where it can do no harm, while at the same time enhancing the flow of clean air inwards.

The venting hood

The venting hood is the one component of local exhaust ventilation design where the unclean air is coursed through on its way out of the room. This component may be made out of any one of many industrial grade metals, although aluminum and its alloys are most commonly used in construction. Depending on the local exhaust ventilation design, the venting hood may be fitted with an air filter that traps solid particles.

The exhaust fan

The exhaust fan is the main component in local exhaust ventilation design that is responsible for drawing unclean air outwards from a room. Comprised of three or four metal blades that spin around in a fast motion, the exhaust fan is usually powerful enough to draw out unwanted air, smoke, and strong odors from a room.

The exterior ducts

From the fan, the unclean air is coursed out through one or more exterior ducts. These are components of local exhaust ventilation design that can typically be seen from the outside. These ducts basically serve as an exit point for the unclean air that is drawn out by the ventilation system, and they disperse the contaminants in a manner that ensures the utmost safety to the people in the immediate vicinity.

Shopping around for the best model for your needs

Local exhaust ventilation design comes in many forms and sizes, and thorough knowledge of the different designs will help you make the right decision when it comes time to make a purchase. And since a ventilation system is an investment that you will continue to benefit from for a long time to come, it is important to make your decision wisely. By taking the time to choose from the different models carefully, you can reap all the advantages that modern local exhaust ventilation design can provide…and you won't have to break the bank to do so.
