Slide Gate / Guillotine Dampers

From design to fabrication, Kelair's slide gate & guillotine dampers are manufactured with the highest quality materials to the exact specifications of clients.

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.

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.

Diverters & Tee Dampers

Diverters & 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.
