Types of Ventilation Systems

Maintaining a healthy and comfortable indoor environment for your employees and patrons is crucial. One of the key components of creating a safe, productive, and efficient space is having a reliable ventilation system in place. 

Ventilation systems play a significant role in circulating fresh air, removing pollutants, controlling humidity levels, and regulating temperature. But with so many different types of ventilation systems available on the market, how do you know which is best for your specific facility needs?

Let’s explore the various types of ventilation systems, their benefits, and considerations for choosing the right system for your facility. So, whether you are looking to upgrade your current system or are designing a new industrial ventilation system, this post will provide valuable insights and guidance to help you make an informed decision.

Different Types of Ventilation Systems for Industrial Applications

If your facility or work environment emits hazardous gasses, fumes, airborne particles, or excessive heat, an industrial ventilation system is required. These systems ensure a safe and comfortable workplace environment while guaranteeing the contaminants don’t negatively affect the quality of your products, such as in Aerospace and Food Manufacturing facilities.

There are two basic types of industrial application ventilation systems: Dilution and Local exhaust ventilation systems. Each type has its unique features and benefits, depending on the specific needs of your facility.

Dilution Ventilation System

Dilution ventilation systems mix clean and fresh air with contaminated air, which is incredibly helpful when controlling fire and health hazards. However, it’s not applicable in controlling fumes and highly toxic or high concentrations of contaminants.

Benefits of a dilution ventilation system:

  • Highly effective in controlling low toxic gasses and chemicals
  • Ideal for mobile or dispersed contaminant sources
  • Can effectively control flammable or combustible gasses or vapors

Local Exhaust Ventilation System

A local exhaust ventilation system is essential for a vacuum that pulls air out of an area or space. These types of ventilation systems are typically installed at the release points of contaminants (dust, gas, fumes, etc.) to reduce their concentration in the workroom below TLVs. Any room in a facility where the emission of heat or contaminants is high is where a local exhaust ventilation system should be installed.

LEVs are also a type of ventilation hood system since they are composed of a heavy duty industrial fan that draws out the air through a hood close to the contaminant source. Apart from the hood and heavy duty industrial fan, some components include the ductwork, fans, filter, and exhaust stack to ensure adequate capture and removal of harmful contaminants.

Benefits of a local exhaust ventilation system:

  • Requires less energy compared to a dilution ventilation system
  • Removes contaminants at the source, ensuring they don’t spread through the facility
  • Can handle numerous types of pollutants, including dust and metal fumes
  • Ideal in demanding and rigorous industries where toxic fumes and substances are regularly emitted
  • Less makeup air to heat or cool in indoor workplaces
  • Reduced amount of makeup air as small amounts of air are being exhausted
  • Lessen the risk of employees developing COPD and other health problems
