Ventilation duct pipe with collar and reducer Capricorn 160/110/1000 mm gray

Capricorn ventilation duct pipe with collar and reducer 160/110/1000 mm in gray is designed for extracting air in residential and light-commercial ventilation systems. The duct provides a transition from a 160 mm nominal diameter to 110 mm within a single 1000 mm length, incorporating a collar for secure connection. Constructed for mounting in exhaust lines, the pipe enables compact routing where a size reduction is required between two sections of ductwork.

Advantages

The integrated reducer and collar simplify installation by eliminating the need for separate adapters and additional sealing elements. The single-piece design reduces the number of joints, decreasing potential air leaks and improving flow integrity. Its standardized nominal diameters make it compatible with common ventilation components and fittings. The gray finish is suitable for concealed or semi-exposed installations and provides a neutral appearance that integrates with typical HVAC layouts.

Suitable for

• Exhaust ventilation in residential kitchens, bathrooms and utility rooms
• Light-commercial ductwork where a 160 mm to 110 mm transition is needed
• Inline connections in confined spaces requiring a compact reducer

Key specifications

• Nominal diameters: 160 mm and 110 mm (integrated reducer)
• Length: 1000 mm
• Material: rigid ventilation-grade pipe (gray finish)
• Connection type: collar-integrated reducer for direct mating with compatible ducts and fittings
• Application: exhaust/air extraction

How to use

Install the Capricorn duct pipe inline between the larger and smaller duct sections, positioning the 160 mm end toward the upstream duct and the 110 mm end toward the downstream connection. Ensure mating components are clean and free of debris, then slide each duct end over the corresponding collar or insert and secure according to local installation practices — typically with clamps, screws or approved sealing tape where required. Verify that the reducer is oriented to provide smooth airflow and avoid sharp bends immediately adjacent to the transition.

Usage recommendations

For reliable performance, inspect connections for gaps and apply appropriate sealing materials on joints to prevent air leakage. Avoid placing the reducer near active bends or sharp turns that can cause turbulence; provide straight run sections of ductwork before and after the reducer when possible. Use compatible dampers or silencers upstream or downstream as needed for system balancing and noise control.
