## Summary description

TŁUMIK TO-LC/5DB is an acoustic muffler (attenuator) designed to reduce noise by approximately 5 dB. Supplied under the No name brand with MPN TO-LC/5DB and EAN 5902887043024, it is intended for inline installation in ventilation or duct systems to lower airborne sound levels. Use cases include HVAC noise control, ventilation systems in residential and commercial buildings, and equipment exhaust attenuation.

## Long description

TŁUMIK TO-LC/5DB is an inline acoustic attenuator designed to reduce airborne noise by approximately 5 dB when installed in ductwork or ventilation systems. It is intended for use where a modest reduction in sound pressure is required without significant impact on airflow. The device is suitable for integration into residential and light commercial HVAC systems and for situating on equipment exhaust ducts to help lower perceived noise levels from fans or motors.
Advantages
The attenuator provides a small but measurable noise reduction while preserving system airflow and requiring minimal installation space. Its passive design needs no power supply or active controls, and it can be installed in straight duct runs with standard fittings. Constructed for inline placement, it helps reduce tonal and broadband noise components arising from mechanical equipment and air movement.
Suitable for
Reduction of fan and motor noise in HVAC duct systems
Noise control on exhaust or intake ducts of equipment
Ventilation systems in apartments, offices, and light commercial premises
Applications requiring modest attenuation without major pressure drop
Key specifications
Attenuation level: approximately 5 dB across typical ventilation frequency ranges
Type: inline acoustic attenuator for duct installation
Application: intended for airborne noise reduction in ventilation and exhaust systems
Operating principle: passive acoustic absorption/attenuation
Installation: suited for straight duct sections with compatible diameter fittings
How to use
Select an appropriate straight section of duct where the attenuator can be inserted without sharp bends immediately upstream or downstream. Verify the duct diameter and ensure compatible connections or adaptors for a secure fit. Install the attenuator according to standard ductwork practices, sealing joints to prevent air leakage. After installation, inspect the system for changes in airflow and listen for the expected reduction in noise levels; make any necessary adjustments to adjacent duct supports or isolation to avoid structure-borne transmission.
Usage recommendations
For best results, install the attenuator at a distance from noise sources that allows airflow to develop (typically several duct diameters). Avoid placing it directly adjacent to sharp turns, dampers, or fittings that cause turbulence. Periodic inspection for dust buildup or obstruction is recommended to maintain acoustic performance and airflow.
