Round Duct UN Ø150 mm, 0.5 m length (single piece)

Round Duct UN Ø150 mm, 0.5 m length (single piece) is a straight section of circular ventilation ducting with a nominal internal diameter of 150 mm and a length of 0.5 m. Manufactured for use in ventilation and HVAC systems, this single-piece straight duct is intended to connect with other Ø150 mm components to create continuous air distribution paths for supply, exhaust, or recirculation. The product is suitable for residential and light commercial installations where a compact, standardized duct section is required for routing air through ceilings, walls, and service spaces.

Advantages

This Ø150 mm round duct provides a standardized connection diameter for easy integration with compatible fittings and accessories. The 0.5 m length offers a balance between handling convenience and installation flexibility, reducing the number of joints needed compared to shorter segments. The single-piece form simplifies inventory management and allows installers to add individual segments without buying multi-packs. Designed for common ventilation applications, the duct supports typical air volumes and can be used in straight runs or combined with elbows, reducers, and grilles to form complete duct systems.

Suitable for

• Supply and exhaust air distribution in residential ventilation systems
• Light commercial HVAC branch runs and exhaust ducts
• Connecting fans, air handling units, and diffusers with Ø150 mm spigots
• Routing air through attics, ceilings, service voids, and utility shafts

Key specifications

• Nominal internal diameter: 150 mm
• Length: 0.5 m
• Form: straight circular duct section
• Connection: designed to mate with other Ø150 mm fittings and ducts
• Application: ventilation and HVAC air distribution for supply, exhaust, or recirculation

How to use

Install the round duct by aligning its ends with compatible Ø150 mm fittings or adjacent duct sections and secure connections according to the chosen joining method (clamps, slip-fit couplings, or sealant, depending on system design). Ensure a continuous, supported run by providing suitable hangers or brackets at recommended spacing for duct weight and orientation. Trim if necessary to achieve the required length and check for proper airflow direction and unobstructed internal passage before commissioning the ventilation system.

Usage recommendations

For best performance, use the Ø150 mm duct in systems designed for that diameter, avoid excessive bending near connections, and seal joints to minimize air leakage. Combine this straight section with appropriate elbows, transition pieces, and grilles rated for ventilation use. Inspect and clean ducts periodically according to local maintenance guidelines to maintain airflow and indoor air quality.
