Shut-off damper for round air duct | for ventilation | air handling systems | D100 | silver | galvanized steel | 100USO

Technical Specifications

Product type: air shut-off damper for round duct
Purpose: for closing or regulating airflow
Suitable for systems: ventilation, air handling and air conditioning systems
Duct type: round
Diameter: D100
Outer diameter: 100 mm
Control: manual
Actuator: handle
Material: galvanized steel
Color: silver
Operating pressure: up to 1500 Pa
Air type used: supply, exhaust or recirculated air

Functions

Airflow shut-off – allows complete closure of airflow in a round duct
Airflow regulation – the handle allows the damper to be partially opened or closed to regulate the amount of passing air
Supply air control – suitable for regulating the flow of fresh air supplied into rooms
Exhaust air control – can be used for extracting air from bathrooms, kitchens, warehouses, garages or technical rooms
Recirculated air control – allows control of airflow in systems where air is returned or redistributed between zones
Manual control – the damper is operated by a mechanical handle, eliminating the need for an electric actuator or automation
Ventilation system balancing – helps adjust airflow between different rooms or duct branches
Isolation of a separate duct branch – allows temporary restriction or closure of airflow in a specific part of the system
Use in air conditioning systems – suitable for airflow control in air conditioning systems where operating pressure does not exceed 1500 Pa
Mechanical operation without power supply – functionality remains independent of electricity supply, ensuring simple and reliable operation

Applications

For household users: This damper is suitable for ventilation systems in private houses, apartments, garages, basements or utility rooms. It allows easy regulation of airflow to different rooms, for example reducing air supply to a less frequently used area or closing an unused duct branch.

For electricians/installers: For installers, it is a convenient component for round duct systems where manual airflow control is required. The D100 diameter is commonly used in smaller ventilation lines, making the damper suitable for residential and small commercial projects.

For ventilation system specialists: This damper is useful for system balancing, airflow distribution and control of individual ventilation branches. It can be used in both newly installed and upgraded systems.

For engineers/designers: When designing ventilation or air conditioning systems, this damper can be specified as a simple manual airflow regulation component. It is suitable for systems with operating pressure not exceeding 1500 Pa.

For commercial facility maintenance specialists: Suitable for ventilation systems in offices, warehouses, workshops, technical rooms or small commercial facilities where a simple, reliable and economical airflow control solution is required.

Advantages

Ability to shut off airflow – allows isolation of a separate duct section or room
Ability to regulate airflow – helps balance the ventilation system
Galvanized steel construction – durable, long-lasting and more resistant to corrosion
Suitable for supply, exhaust and recirculated air

Disadvantages

Manual control only – not suitable where automatic airflow control is required
No electric actuator – cannot be controlled remotely without additional solutions
Suitable only for D100 ducts – duct diameter must be verified before purchase
