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 Dampers (VIV), Inlet Vane Control Dampers (IVC), Radial Vane Dampers, Inlet Valve Dampers and Vortex Dampers 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.

 

Kelair’s Inlet Vane Dampers provide an effective way to reduce energy consumption by regulating airflow, which directly lowers operational costs. This reduction in energy use leads to a faster return on investment, making them a cost-effective solution for industrial applications. Over time, these savings add up, improving the overall efficiency and sustainability of a facility’s ventilation system.

Kelair’s Inlet Vane dampers have a central hub surrounded by multiple blades and are used primarily in clean air/gas environments without particulates. They are appropriate for both volume control and fan shutoff. This damper has the added benefit of easily allowing field changeable air pre-spin rotation.

Kelair’s dampers are specifically engineered with ease of maintenance in mind, ensuring minimal downtime and streamlined servicing. Their design allows for quick inspections and adjustments without requiring extensive disassembly, making them a reliable choice for long-term operation. By minimizing maintenance-related interruptions, these dampers enhance efficiency and reduce labor costs.

*Operational testing and calibrating are completed at the factory prior to installation.

Frequently Asked Questions

What are examples of typical inlet vane damper applications?
Inlet vane dampers are often used in facilities that have complete control of their ventilation systems. These types of ventilation systems include flue gas, automotive, and oven recirculation systems.
What does proper care look like for an inlet vane damper?

Depending on the inlet vane damper's environment and age, blades can warp or bend over time. Proper care involves regularly checking each blade to ensure there is no warping, twisting, or buildup of debris that could prevent the blade from performing correctly. Ideally, blade inspections should occur annually or during every outage, whichever comes first.

What is the minimum information I need to get a quote on a damper?
