Reliable Low Leakage Air Control

Our duct dampers are engineered for exceptional leakage prevention, with rates as low as 3% at 1000 Pa. The unique opposed or parallel blade mechanism offers precise adjustment, while robust extruded aluminium or galvanized steel construction ensures reliability under pressure. Designed as per AMCA/SMACNA standards, these dampers integrate seamlessly with HVAC ducting for optimal air distribution and minimum losses.

Flexible Operation and Mounting

Adaptability is central to this product: choose between manual or motorized (optional actuator) control, and select from handle, locking quadrant, or actuator-compatible controls. The duct damper is easy to install thanks to slip-on or flange end connections, and is suitable for both new projects and retrofit solutions. Round or rectangular shapes and a wide range of sizes accommodate various airflow needs.

Durable Design for Demanding Environments

Constructed with quality extruded aluminium, galvanized or mild steel, these dampers are powder coated or factory galvanized to withstand harsh HVAC conditions. Their robust welded or riveted build guarantees high durability, making them ideal for pressure up to 1500 Pa and temperatures from -10C to 80C. Simple manual cleaning ensures maintenance remains straightforward.

FAQs of Low Leakage Duct Damper:

Q: How does a low leakage duct damper improve HVAC system efficiency?

A: A low leakage duct damper minimizes air losses by maintaining a leakage rate below 3% at 1000 Pa, resulting in improved energy efficiency, reduced operational costs, and stable environmental control within HVAC systems.

Q: What types of blades and materials are available for these dampers?

A: These dampers can be equipped with either opposed or parallel blades, manufactured from extruded aluminium or galvanized steel. The construction is available in both welded and riveted formats based on application requirements.

Q: Where should I install this duct damper in my ventilation system?

A: The damper is designed for duct mounting and can be installed directly in air handling units, supply or return ducts, and ventilation plant systems wherever precise airflow control is required.

Q: What operation and control options are provided?

A: Operation can be manual via handle or locking quadrant, or motorized by fitting an optional electric actuator. This versatility enables integration with both existing and new automation setups.

Q: When should I opt for a motorized actuator versus manual operation?

A: A motorized actuator is recommended when remote or automated control is needed or for dampers located in areas difficult to access. Manual operation is cost-effective and suitable for applications where periodic adjustment suffices.

Q: How can I ensure the damper is maintained in top condition?

A: Regular manual cleaning of the dampers external surfaces and periodic function checks will help maintain optimal performance and extend product life.

Q: What are the main benefits of using this low leakage duct damper?

A: Benefits include high durability, reliable air control, pressure resistance up to 1500 Pa, customizable sizes from 100mm to 1000mm, and substantial leakage prevention, enhancing overall air system performance.
