Custom design and fabrication of dampers
Kelair specializes in custom design and fabrication of dampers and assemblies to meet your specific application requirements for example: poppet dampers, louver style diverter dampers and louver style tee dampers. Typically poppet dampers are used to enhance the performance of fabric filters (baghouse), incinerators and thermal oxidizers. Louvers can be added to Kelair’s diverter or Tee dampers to provide additional means of shut-off and flow control.
We can customize dampers to meet specific pressure, temperature, airflow regulation, and other important operational conditions. Let us assist you in selecting the most cost effective and efficient damper design, one that you have not found on any of the previous pages of this website. Besides a totally custom industrial damper, Kelair offers accessories and features that will serve to heighten the efficacy and efficiency or your industrial damper.

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 1900 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.
