Pollution Control Industrial Dampers

Kelair understands the unique process air and gas flow challenges of pollution control equipment manufacturers. 

You require damper products that are engineered to the exacting standards that you, your customers and regulators demand. Ideal for manufacturing facilities with emission control systems and leveraging VOC (volatile organic compound) abatement techniques, Kelair dampers have become “must have” components in pollution control equipment for many industrial companies.

Kelair VOC control system dampers are designed and constructed to meet and exceed the most stringent equipment specifications for air flow, temperature, actuation, material choice and cost value. Airflow control dampers are used to transport and control how pollutants enter VOC control equipment, and affect energy efficiency and total system performance.

Frequently Asked Questions

Who regulates VOC emissions?
The US EPA regulates VOC emissions at the federal level. The EPA’s 40 CFR 59 outlines VOC emission standards for both consumer and commercial products. Additionally, the Clean Air Act provides strict requirements regarding air pollution and emission. Facilities that fail to meet the requirements set by the Clean Air Act face excess emissions penalties.
How can you test for VOCs in an industrial facility?
One of the more common methods for VOC testing involves using a photoionization detector (PID). PIDS use high-energy UV light to measure VOC levels and offer quick and reliable results. The EPA’s official website provides an extensive list of validated test methods for VOCs and other contaminants.
What are examples of VOCs?
VOCs can include both natural and manufactured compounds such as fossil fuels. Common examples of VOCs that might be present in an industrial facility include sulfur dioxide, nitrogen oxide, and methylene chloride.
How harmful are VOCs to industrial facility workers?

The health effects of VOCs vary depending on several factors, such as the level of exposure and the amount of time exposed. Generally speaking, VOCs can cause irritated eyes, difficulty breathing, damage to the central nervous system, and even cancer.
