Inline duct fan VENTS DUCTED 125 QUIETLINE — Ø125 mm, low-noise ventilation unit

The VENTS DUCTED 125 QUIETLINE is an inline duct fan designed for ventilation systems with a 125 mm duct diameter. It is intended for low-noise air extraction or supply and is suitable for installation inside round ducts to maintain airflow while limiting sound transmission. The compact cylindrical housing and integrated mounting flange allow connection to standard ducting and fittings, making it compatible with small duct networks in residential and light-commercial settings.

Advantages

The unit combines low operational noise with steady airflow performance, reducing disturbance in living spaces. Its compact inline design preserves duct routing flexibility and simplifies installation without large external housings. Built for continuous operation, the fan offers reliable ventilation for moisture and odor control while integrating with standard ventilation components and duct diameters.

How to use

Install the fan inside a straight section of 125 mm round duct, securing it with the integrated mounting flange or clamps as appropriate. Ensure the airflow direction arrow on the housing matches the intended supply or exhaust flow. Make electrical connections following local wiring regulations and the product’s installation instructions; use a qualified electrician if required. After installation, test the unit to confirm correct airflow and verify that duct joints are sealed to prevent leakage and reduce noise.

Usage recommendations

Place the fan away from sharp bends or immediate obstructions to maintain performance and minimize noise. For best results in bathrooms and kitchens, combine the inline fan with appropriately sized ducting and terminal grilles, and perform periodic checks for dust buildup. Follow maintenance intervals recommended by the manufacturer to preserve low-noise operation and airflow efficiency.
