Diverter & Tee Dampers

Tee dampers and diverter dampers from Kelair are available in the classic "T" formation as well as a variety of possible configurations.

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.  Proof of 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

Butterfly Dampers

Butterfly dampers 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.

Louver Dampers

Louver Dampers

Kelair's Louver Dampers are applicable for light duty industrial ventilation to heavy duty, high volume flow control and isolation applications. Parallel or opposed blade, outboard bearings and linkage, adjustable packing glands and double skin airfoil vanes are all standard on louver dampers from Kelair.

Slide Gate / Guillotine Dampers

Slide Gate / Guillotine Dampers

These types of slide gate or gullotine 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 & Tee Dampers

Diverter Dampers also called Tee Dampers are used to redirect air stream (hot gas or otherwise) 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.

Refractory Dampers

Refractory Dampers

Kelair’s Refractory dampers are manufactured to withstand temperatures up to 1900 F in corrosive, particulate and/or process gas environments. Refractory dampers from Kelair help reduce heat loss to surroundings and provide erosion protection for the frame.

Inlet Vane Dampers

Inlet Vane Dampers

Inlet Vane Dampers work with fans and blowers to enhance their performance by controlling air volume and fan shut-off. They can be mounted to the fan inlet to conserve power at reduced airflow. These types of dampers reduce fan pressure without reducing speed. Kelair’s design boasts no external linkage, eliminating pinch points and damage to the assembly.

Backdraft Dampers

Backdraft Dampers

Kelair’s Backdraft dampers are engineered to allow airflow in one direction and prevent reverse airflow. They are typically wall or roof mounted and applied to mechanical HVAC ventilation systems. 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. Backdraft dampers can utilize pneumatic or electric actuators or be gravity controlled.

Stack Cap Dampers

Stack Cap Dampers

Stack Cap Dampers or Stack Isolation Dampers both isolate the stack opening to prevent foreign material from entering when not in use and conserve warmth when the stack is shut down or during maintenance. Kelair’s Stack Cap dampers deliver accurate air flow and isolation at high temperatures and high volumes, reducing the stack effect when offline thereby protecting ductwork from the elements.
