Revenue model

1. Custom Industrial Dampers: Kelair manufactures custom-engineered industrial dampers to order, including butterfly dampers, louver dampers, slide gate/guillotine dampers, diverter & tee dampers, refractory dampers, inlet vane dampers, backdraft dampers, and stack cap dampers. Pricing is quote-based as each unit is custom-engineered for specific application requirements.
2. Industrial Ducting: Custom-built industrial ductwork fabricated from carbon steel, stainless steel, or Hastelloy for pneumatic conveying, air pollution control, and industrial ventilation systems.
3. Isolation and Butterfly Valves: Isolation valves and butterfly valves for gas and liquid flow control in pipelines, offered alongside damper products for complete system control.
4. Damper Actuators: Electric, pneumatic, and manual damper actuators as standalone components or integrated with damper assemblies, available as factory-installed or customer-supplied options.

Core offering

Kelair Dampers Inc. designs, engineers, and manufactures custom industrial dampers and related flow-control equipment — including butterfly, louver, slide gate/guillotine, diverter & tee, refractory, inlet vane, backdraft, and stack cap dampers, plus actuators, industrial ducting, and isolation and butterfly valves. Its products are built to order for high-temperature, high-pressure industrial airflow control, isolation, and modulation applications.

Product overview

Kelair Dampers is a custom industrial damper manufacturer offering a comprehensive portfolio of airflow control products. The core product line includes eight distinct damper types: Butterfly Dampers (most economical solution for flow control and isolation), Louver Dampers (multi-vane design for precise modulation in large ducts), Slide Gate/Guillotine Dampers (heavy-duty isolation with near-zero leakage), Diverter & Tee Dampers (for redirecting airflow between outlets), Refractory Dampers (high-temperature versions up to 2100°F), Inlet Vane Dampers (for fan performance optimization), Backdraft Dampers (gravity-operated one-way flow), and Stack Cap Dampers (for exhaust stack isolation). Supporting these dampers are complementary products including Damper Actuators (electric, pneumatic, and manual options), Industrial Ducting (custom fabricated in various metals), Isolation Valves, Butterfly Valves, and Special Applications (custom configurations). All products are custom-engineered and fabricated to order in Bellwood, Illinois, with typical lead times of 2-5 weeks depending on configuration and actuation requirements.

Regional players

• Cesoni: Cesoni is a European manufacturer of industrial dampers and louver dampers for high-temperature and process applications, comparable to Kelair on product type but serving a different (mainly European) geography.

Direct peers

• Duro Dyne: Duro Dyne manufactures HVAC and industrial ductwork accessories including dampers, actuators, and duct components, overlapping with Kelair's industrial ducting, isolation valves, and actuator offerings.
• Ruskin Company: Ruskin is one of the largest US manufacturers of industrial dampers, louvers, and air-handling equipment, directly competing with Kelair across commercial and industrial damper categories including high-temperature and heavy-duty applications.
• Nailor Industries: Nailor manufactures commercial and industrial dampers, louvers, and air-handling components, overlapping with Kelair in louver, butterfly, and control dampers for HVAC and process applications.
• Pottorff: Pottorff specializes in industrial dampers and louvers, including high-pressure, high-temperature, and specialty isolation dampers, making it a direct product-line competitor to Kelair's refractory and specialty dampers.
• Industrial Louvers Inc. Industrial Louvers manufactures a focused line of dampers and louvers including heavy-duty industrial models, positioning it as a close competitor in the same custom-engineered niche that Kelair serves.

Broad incumbents

• Greenheck Fan Corporation: Greenheck is the largest US manufacturer of commercial and industrial ventilation equipment, including a full line of industrial dampers, louvers, and fans — competing with Kelair on custom-engineered industrial projects while serving a much broader HVAC portfolio.
• Johnson Controls: Johnson Controls is a global building systems incumbent whose HVAC and building controls portfolio includes industrial dampers and actuators, competing with Kelair on integrated damper-actuator packages for large facility customers.
• Honeywell Building Technologies: Honeywell's building technologies business includes actuators, dampers, and HVAC controls — relevant as an actuator-tier competitor to Kelair's electric and pneumatic damper actuator packages integrated with building automation systems.

Others

• CECO Environmental: CECO is both a Kelair customer (over a decade on process diversion and hot gas bypass systems) and an adjacent competitor providing engineered dampers and environmental compliance equipment — making it a hybrid peer/buyer relationship.
