Stack Isolation Dampers isolate the stack opening to prevent foreign material from entering
These types of dampers are your first line of defense against the elements. Stack Cap dampers prevent rain and snow from entering the stack. They are very practical on smaller diameter exhausts and can be counterweighted for pressure relief or assistance with fail mode. Stack Cap dampers are frequently used in the Petrochemical, chemical, and cement industries where they are installed in furnaces, heaters, and reformers for gas shutoff of ducts. Stack cap dampers are utilized in turbine exhaust applications to divert the exhaust gas to either the bypass stack or to pass through to a waste heat boiler.
Stack Cap Isolation dampers provide isolation at high-temperature levels, accurate airflow, and protection against the elements. Additionally, these dampers minimize the stack effect of a system when it is offline. The stack cap isolation dampers are regularly used in heat recovery steam generator (HSRG) exhaust stack applications and as an energy-saving shutoff in gas plants due to their weather protection efficiency.

Kelair's custom-designed industrial ductwork is used in various applications, including pneumatic conveying, air pollution control, and industrial ventilation systems.
Butterfly dampers used by Kelair have the simplest design and the fastest turnaround. They are the economical choice for applications ranging from light duty to heavy duty and low temperature to high temperature.
Kelair's Louver Dampers are applicable for both light, and heavy-duty industrial ventilation for high volume flow control, and isolation applications. This damper modulates the flow of air and gas in dry or wet conditions or can shut them off altogether.
Slide Gate / Guillotine Dampers
These types of slide gate or guillotine dampers are used primarily as shut off devices. Kelair's rugged, heavy duty designs are available round or square with sizes from 4" up to 96" making them an ideal solution for industrial applications.
Diverter & Tee Dampers
Diverter Dampers or Tee Dampers are used to redirect air stream from one outlet to another. These types of dampers are widely used in incineration systems to divert process air and gas to the incinerator or by-pass to the atmosphere.
Kelair’s Refractory dampers are manufactured to withstand temperatures up to 2100 F in corrosive, particulate and/or process gas environments. This unique design helps reduce heat loss and provide erosion protection for the frame.
Inlet Vane Dampers
Inlet Vane Dampers work with fans and blowers to enhance their performance by controlling air volume and fan shut-off. Kelair’s design boasts no external linkage, eliminating pinch points and damage to the assembly.
Kelair’s Backdraft dampers are engineered to allow airflow in one direction and prevent reverse airflow. Backdraft dampers control airflow in ventilation systems either to modulate or to shut off moving air through a fan opening when it is turned off.
Stack Cap Dampers
Kelair's Stack Cap Dampers isolate the stack opening to prevent foreign material from entering and conserve warmth when the stack is shut down. The dampers deliver accurate airflow and isolation at high temperatures, reducing the stack effect.
