Dampers that provide dependable, low leak isolation
Slide gate dampers or guillotine dampers are a type of industrial damper commonly used when low leakage and low-pressure drop are required. They perform best where flow control is not critical but low leakage is. These types of dampers are well suited for situations where isolation of an air stream or gas flow occurs frequently due to routine maintenance, inspection or repair. Kelair’s heavy duty construction allows for slide gate or guillotine dampers to function reliably in demanding environments with corrosive gas, particulates and high temperature.
Kelair’s slide gate dampers provide numerous benefits to your application. They cut through heavy particulates with smooth opening and closing. They have fewer moving parts, therefore less maintenance. If space is an issue, guillotine dampers require less of it along the duct (flange to flange). Overall, slide gate or guillotine dampers benefit the customer with solid, long term operational savings.

More 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.
