Industrial Exhaust Fans and Ventilation

In an industrial facility, it is important to maintain a safe and healthy working environment for employees. Achieving this goal entails several considerations—including preserving air quality in enclosed settings regularly exposed to heat, humidity, exhaust, and airborne chemicals, all of which severely impact breathability. For these situations, fans and blowers play a critical role as they expel poor quality air from and introduce clean air into a facility.

With these concerns in mind, the Indventech team provides a wide range of industrial fans and blowers to suit the needs of various customers, such as flow direction, flow speed, and volume capacity. Our product offerings—including centrifugal and axial fans—find use in applications across a diverse set of industries, such as biotechnology, education, food and beverage, manufacturing, oil and gas, pharmaceutical, and wastewater treatment.

Ventilation Fans for Industrial Facilities

An effective ventilation system offers advantages besides reducing health risks associated with contaminated air. Ventilation is essential for regulating the physical damage caused by moisture and minimizing the effects of chemical cleaning materials used on floors, kitchens and bathrooms. In manufacturing facilities, ventilation is critical for dust control and keeping the air free of dirt, which causes machines to overheat and potentially harms equipment.

For buildings without air conditioning, fans play vital roles in creating a more comfortable working atmosphere for employees. While fans do not decrease air temperature, they promote circulation and cool a person’s skin through a wind-chill effect. Ceiling fans can prevent heating systems from working extra hard in the winter by pushing hot air towards the ground.

Large centrifugal and axial fans on nearby walls can drive away high exhaust temperatures in facilities that use boilers and other heat-generating equipment. When using the highest quality fans and blowers, these types of strategies can lead to considerable savings in utility bills.

Types of Industrial Fans and Blowers

When incorporated into industrial ventilation systems, both blowers and fans enhance airflow and improve air quality. However, while they are similar in function, they operate under slightly different principles. Fans facilitate air movement through the use of rotating blades, which allow for low-pressure generalized air circulation. On the other hand, blowers use a wheel to propel air at higher speeds in a specific direction.

Fans are typically manufactured in one of two designs:

Centrifugal Fans

Centrifugal fans use blades rotating at high speeds to increase the speed and pressure of air passing through them. The air exiting the fan moves at a 90-degree angle to its entrance direction. Due to their higher pressure capacities, they are often used in corrosive or harsh environments, where chemicals, dirt, humidity, and other contaminants may be heavily present in the air.

Centrifugal fans can be engineered with forward-curved or backward-curved blades. Forward-curved blades move small air volumes with less noise, while backward-curved ones offer faster airspeeds and greater volume capacities for enhanced operating efficiency.

Axial Fans

Similar to centrifugal fans, axial fans use blades to move air; however, the intake and discharge of air occur in the same direction. They are ideal for moving large amounts of low-pressure clean air in applications that require regular flow into and out of a space. Typical use cases include exhaust and ventilation systems for warehouses, paint booths, furnaces, and wastewater pump stations.

Choosing the Right Industrial Exhaust Ventilation

After determining whether a centrifugal or axial fan is the best fit for a facility, there are several other critical factors to consider when selecting the most effective fan for a specific application. Some examples include:

  • Direct drive vs. belt drive: Direct drive fans operate with more noise. While direct drive fans run at higher RPM and are easier to maintain, they do not move as much air as belt-driven models. High-temperature fans exceeding 120 degrees Fahrenheit are almost always belt-driven.
  • Fan location: Fan designs and models relate to their specific locations — on a wall, on a roof or in a duct. Regardless of the area, the primary functional components are similar. By analyzing your building’s structure and determining how the air should flow, you can choose the most optimal location.
  • Cubic feet per minute (CFM): Calculating the CFM represents how much air moves through a room when a fan operates at maximum speed. The larger the area, the higher the CFM must be to efficiently cool or ventilate a room. Local building codes typically contain the necessary information to determine proper CFM ranges.
  • Static pressure: The static pressure is the resistance pressure a fan needs to pull or blow against to move air in a specific direction. The air’s push or pull must be greater than the resistance or no air will move.
  • Noise level: A fan’s noise level can be measured in both decibels and sones. Sone rating calculates how much noise it generates. One sone is equal to approximately 1,000 Hz with a sound level around 40 decibels above a typical level. Suitable ratings can range from around two sones in a private residence to between 25 and 50 sones in a manufacturing facility.

Applications for Industrial Fans and Blowers

Industry professionals in virtually every sector employ the use of fans and blowers to facilitate their operations. The type of industry, environment and process systems contribute to which design is the most effective. At Indventech, our products offer our clients solutions to various applications, from dust control to temperature regulation to air replacement. Our fans and blowers can help alleviate issues associated with extreme temperatures, corrosive environments, dirty airstreams and much more.

Some of the most common industrial applications include:

  • Manufacturing: Fans and blowers are used in manufacturing facilities to reduce noise and control airborne dust and fumes.
  • Oil and gas: Oil and gas facilities include fans in their ventilation systems to control high temperatures and minimize excess noise.
  • Pharmaceutical and biotechnology: Pharmaceutical and biotechnology operations employ fans to maintain air quality and contain potentially hazardous compounds.
  • Power generation and distribution: The power industry requires fans to ventilate enclosed areas and reduce overall operational noise.
  • Research and education: Research labs use fans to ensure they meet air quality standards and reduce the risk of airborne contaminants spreading.
  • Wastewater treatment: Fans and blowers are often used in wastewater treatment facilities to control odors and unwanted airborne contaminants.

Both axial and centrifugal fans are employed in these industries for numerous reasons, such as ensuring air quality, expelling fumes and contaminants, reducing noise, and preventing the start and spread of fire.
