Centrifugal Fans for Industrial Air Pollution Control Systems
Industrial processes that involve combustion or chemical reactions inevitably generate air pollutants. Safely managing these emissions is critical to protecting workers, the environment, and staying compliant with the U.S. EPA’s Clean Air Act, which carries steep penalties for violations.
At the core of every air pollution control system are industrial fans and blowers. From intake to exhaust, fans keep contaminated air moving through scrubbers, boilers, oxidizers, and other control technologies. The right fan design depends on factors such as local regulations, airstream composition, and operating scale—making proper specification essential for both performance and compliance.
Primary Industries for Air Pollution Control Applications
Pollution control applications are necessary for any industry that produces volatile organic compounds (VOCs) or hazardous air pollutants (HAPs) as byproducts of their operations.
- VOCs (Volatile Organic Compounds): Chemicals with high vapor pressure and low water solubility, often found in solvents, fuels, paints, and refrigerants.
- HAPs (Hazardous Air Pollutants): Toxic substances known to cause cancer, reproductive harm, or environmental damage. Examples include benzene, mercury, and asbestos.
The EPA regulates emissions across a wide range of industries, including:
- Agriculture, food & forestry
- Chemical production & distribution
- Electric utilities
- Energy engines & combustion
- Foam, fiber, plastic & rubber products
- Metals production
- Mineral processing
- Oil & natural gas
- Petroleum refineries & distribution
- Power generation
- Semiconductor manufacturing
- Solvent use & surface coating
- Sterilizers
- Waste management
Industrial Air Pollution Control Applications & Solutions
Centrifugal fans and blowers play a critical role in a wide range of air pollution control systems. Below are the applications we most often support:
Selective Catalytic Reduction (SCR)
Converts harmful nitrogen oxides (NOx) into safe nitrogen and water using a variety of catalysts.
Destroys hazardous gases through combustion, converting them into water vapor and carbon dioxide.
Removes or neutralizes toxic gasses and particulates from the airstream.
Reduces the concentration of contaminants in plant emissions by mixing exhaust with fresh air before release.
Combustion & Flue Gas Recirculation (FGR)
Recycles exhaust gas back into the combustion chamber to lower Nitrogen Oxide (NOx) emissions.
Fan Selection & Specification for Pollution Control Fans
Air pollution control applications demand fans that are engineered for their environment—whether that means withstanding high temperatures, resisting corrosion, delivering high efficiency, or operating leak-tight under pressure. Selecting the right fan depends on your airstream, operating conditions, and regulatory requirements. The best approach is to work with an application engineer who can guide you through the specification and design process.

FEATURED FAN
Pollution Exhaust Fan with OSHA Guards for Worker Safety
Designed for pollution control applications in demanding manufacturing environments, this custom exhaust fan delivers both worker safety and regulatory compliance.
This heavy-duty pollution exhaust fan was engineered with OSHA-approved guards to protect workers from accidental contact with moving blades while maintaining high-performance ventilation. Powered by a 20 HP motor with a V-belt drive, the system includes a ceramic felt shaft seal and flanged inlet/outlet connections to minimize considerable gas leakage. A bolted access door allows for safe and efficient maintenance.
The fan’s partially backward-inclined angled blade minimizes material buildup, enhances efficiency, and supports compliance with strict EPA emissions regulations. By replacing exhaust air with fresh air, it helps manufacturers maintain a safe, clean, and compliant working environment.
- Product Type: IEAH (industrial exhauster)
- Description: Class 20, Arr. 9, 150ºF max temp design
- Performance: 5,000 CFM @ 13″ wg static pressure
- Features: Custom OSHA safety guards; 20 HP motor; ceramic felt shaft seal; flanged inlet/outlet; bolted access door
Air Pollution Fan System Arrangements, Accessories & Design
All of the fan arrangements and accessories could be viable options for one or more pollution control applications. Two recommendations apply almost universally: install vibration and temperature sensors, and ensure proper installation and maintenance. Beyond that, the design is application- and environment-specific.
In pollution control systems, getting the design right the first time is critical. A misstep in performance can risk health, safety, compliance, and costly downtime. That’s why it’s essential to choose a fan designed for reliability, backed by engineering expertise, and supported by a partner you can trust.
