## Summary description

Heatpex BL 125 is an exhaust silencer/muffler with a 1 m length designed for airflow and noise reduction in ventilation or duct systems. Manufactured by Heatpex (MPN 520103001, EAN 5908226244701), it serves to lower acoustic emissions and smooth airflow in HVAC installations, duct runs, or industrial ventilation applications where a 125 mm connection diameter is required.

## Long description

Heatpex BL 125 is an exhaust silencer / muffler with a 1 m length designed to reduce noise and smooth airflow in ventilation and duct systems. With a 125 mm connection diameter, the silencer is intended for installation in HVAC ducts, extractor runs and industrial ventilation lines where attenuation of acoustic emissions and improved downstream flow stability are required. The straight cylindrical body and internal acoustic attenuation materials are arranged to lower broadband noise without creating excessive pressure drop.
Advantages
The silencer provides measurable reduction of exhaust and duct-borne noise while maintaining airflow efficiency through a 125 mm connection. Its 1 m length increases the acoustic absorption path, reducing mid- and high-frequency components typical for fans and extractors. Designed for inline mounting, the unit supports stable flow conditions and can be combined with standard duct fittings. Construction and materials are selected to balance sound attenuation and resistance to common ventilation environment conditions.
Suitable for
 Residential and commercial ventilation ducts with 125 mm diameter
 Kitchen extractor and bathroom exhaust systems
 Small industrial ventilation lines and local exhaust systems
 Inline fan installations requiring noise reduction
Key specifications
 Connection diameter: 125 mm
 Length: 1 m
 Function: airflow noise attenuation for exhaust/duct systems
 Form factor: cylindrical inline silencer
 Typical application: HVAC, extractor ducts, industrial ventilation
How to use
Install the Heatpex BL 125 inline in the exhaust or duct run using appropriate connectors for 125 mm diameter ducting. Position the silencer in a straight section of the duct where access for mounting and maintenance is available; avoid sharp bends immediately upstream or downstream to preserve acoustic performance. Ensure secure mechanical connections and seal joints to prevent air leakage. Verify that the installed silencer does not interfere with access panels or required clearances for fans and dampers.
Usage recommendations
For optimal noise reduction, install the silencer at a distance of at least one duct diameter from fans or elbows when possible and combine it with vibration isolation on fan mounts. Periodically inspect the unit for accumulated dust or obstructions and clean as required to maintain airflow and acoustic performance.
