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 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 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
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 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.
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 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.
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 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.
