Engineered for Easy Maintenance and Service
The Inlet Vane Damper is an ideal way to improve performance and efficiency within industrial applications. Vane dampers (also known as Variable Inlet Vane Damper (VIV), Inlet Vane Control Damper (IVC), Radial Inlet Vane Damper, and Vortex damper among others) perform the same basic function: they pre-spin air, in the same direction as the fan rotation, before it enters the fan inlet. This directed air reduces the load on the fan by lowering the fan pressure and airflow. This in turn reduces the energy necessary to operate the fan. Inlet vane dampers reduce the energy costs neccessary to operate fans, enhance their performance and provide long term savings.
Kelair’s Inlet Vane dampers have a central hub surrounded by multiple blades and is used primarily in clean air/gas environments without particulates and able to withstand temperatures up to 2000 degrees F. It is appropriate for both volume control and fan shutoff. This damper has the added benefit of easily allowing field changeable air pre-spin rotation. Designed and engineered for easy maintenance and service, there is no need to remove the Kelair Inlet Vane damper from the fan and it is built to take high airflow velocities.

More Industrial 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 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 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.
