Types of Industrial Dampers
Function of Corrosive Duty Dampers
Corrosive duty dampers are specialized control devices designed to regulate the flow of air and gases within ventilation systems in industrial settings where corrosive elements are present. They are essential components of ventilation, heating, and air conditioning (HVAC) systems in environments exposed to aggressive, corrosive gases, and conditions.
The primary function of these dampers is to prevent the damaging effects of corrosive elements, such as hydrogen sulfide, chlorine, sulfur dioxide, ammonia, and many others, which can significantly erode and degrade equipment over time. By using corrosion-resistant materials in their construction, these dampers effectively ensure the durability of the ventilation systems and the overall infrastructure.
Constructed with materials like Stainless Steel, Fiberglass (FRP), Polyvinyl Chloride (PVC), or Polypropylene, these dampers resist corrosive elements and control the airflow, ensuring the system operates optimally while extending the lifespan of the equipment. They are commonly found in industries such as wastewater treatment plants, chemical plants, pulp and paper factories, and facilities near coastal and marine environments.
Importance of choosing the right damper for the right environment
Choosing the right corrosive duty damper is an essential part of maintaining a robust and efficient ventilation system. The proper damper can prevent system malfunctions, extend the life of your equipment, and ensure a safer and healthier work environment. Here are the key reasons why it’s crucial:
Different industrial settings deal with various corrosive gases and conditions. For example, a wastewater treatment plant might encounter issues with hydrogen sulfide, while a chemical plant might be exposed to a range of corrosive materials from gases to solids. It’s crucial to choose a damper that can effectively resist the specific corrosive elements present in each setting.
The right damper helps maintain optimal airflow within the ventilation system, which can result in energy savings and better operational efficiency. On the contrary, an inappropriate damper might result in increased energy consumption and reduced system performance.
An effective damper can mitigate the risk of equipment failure that could potentially lead to dangerous situations. It also ensures the safe operation of the ventilation system by controlling the airflow of corrosive gases.
The use of a suitable corrosive duty damper can prevent the corrosive gases from eroding the ventilation system and other equipment, thereby prolonging their life and reducing the cost of maintenance and replacements.
Understanding the specific environmental conditions of your industrial setting is key to making an informed decision when choosing the right corrosive duty damper. It’s not just about ticking a box in a list of requirements; it’s about ensuring efficiency, safety, and longevity in a challenging industrial environment.

The Selection Process: Fire-Protection vs Fire-Resistance Ratings
When choosing the right damper for a corrosive environment, it’s essential to consider both fire-protection and fire-resistance ratings. These ratings, while often conflated, serve different purposes in the selection process. Let’s examine each one and its implications:
This rating refers to a damper’s ability to prevent the spread of fire within a system or structure. Fire protection dampers are typically used in HVAC ductwork to stop flames from spreading to other parts of the building. When choosing a corrosive duty damper, it’s important to ensure it has a suitable fire-protection rating that aligns with the specific fire safety requirements of your facility.
On the other hand, fire-resistance rating refers to how long a damper can maintain its structural integrity and function when exposed to fire. Dampers with high fire-resistance ratings can withstand high temperatures for longer periods, thereby providing extra time for safe evacuation and for firefighters to control the situation.
In corrosive environments, where equipment is constantly exposed to harsh elements, both ratings are paramount. A damper with a high fire-protection rating will safeguard the system from fire propagation. Concurrently, a high fire-resistance rating means the damper will hold up under fire, buying valuable time in a dangerous situation.
When selecting a damper, it’s crucial to balance these two aspects based on the specific needs and safety standards of your facility.

Corrosive duty dampers find widespread application across various industrial sectors. Here are some notable examples:
In these facilities, the aggressive nature of wastewater and the chemicals used to treat it produce by-products that can corrode metallic components. For instance, Hydrogen sulfide is a primary gas of concern, found in areas like the sludge drying room, lift stations, and grit chambers. Given the harsh environment, Fiberglass Reinforced Plastic (FRP) is often the material of choice for dampers and other ventilation equipment here.
Many chemical processes generate corrosive gases that pose serious corrosion issues. These substances can range from gases/vapors to solids and often disperse into the air during processing. After understanding the constituents in the airstream or ambient environment, materials for dampers and other equipment are carefully selected. For instance, PVC dampers are frequently employed due to their excellent resistance against many corrosive chemicals.
Various stages in this industry, including pulping, pressing, and bleaching, can create highly corrosive environments. Predominant corrosive gases in this sector are Chlorine and Chlorine Dioxide. Depending on the specific conditions, Stainless Steel or FRP dampers might be used, both offering excellent corrosion resistance.
In coastal and marine facilities, the Sodium Chloride content in saltwater accelerates the oxidation of iron and steel, causing equipment deterioration. For such challenging conditions, dampers with superior corrosion resistance, such as those made from Stainless Steel or specially treated alloys, are crucial.
These are just a few examples. Any industrial sector dealing with corrosive substances, whether in the form of gases, liquids, or solids, can benefit from the careful selection and use of appropriate corrosive duty dampers.
