A pre-assembled Diverter or Tee Damper has many advantages
A Diverter or Tee damper can be a very simple tool with 1 purpose: to divert the flow of air or gas within a system in another direction.
It is typically arranged as a dual damper that resembles a Pipe-T, however it can also be configured at 45 degrees or as a “Pant Leg” version. The 2 openings or outlets are mechanically linked so that when one is opened, the other is closed.
The use of one actuator with a slave linkage saves cost and assures simultaneous operation of both dampers in the assembly. Spring assisted actuators can be utilized to provide a predetermined fail position of the damper vanes. Open/closed auxiliary limit switches are also available.
Tee/Diverters can also perform the trifecta of damper functions: modulate, divert and isolate air or gas flow. This is done by adding a modulation actuator to allow diversion to multiple outlets. In fact, Kelair can manufacture a 3 or 4 way diverter damper which has up to 4 outlets, that runs all 3 of these operations: modulation, diversion and isolation.
*Operational testing and calibrating are completed at the factory prior to installation.

Other Dampers from Kelair Products
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.
