Extension pipe Ferrolux L-250, length 250 mm, diameter 180 mm, black

Ferrolux L-250 extension pipe is a 250 mm long, 180 mm diameter round duct accessory in black finish designed to extend or adapt ventilation runs. It provides a straight, rigid connection between compatible round ducts, fans or appliances with 180 mm outlets and is intended for use in residential and light-commercial ventilation and HVAC installations. The smooth cylindrical profile ensures consistent airflow and simple integration into existing duct systems where an additional 250 mm segment is needed to reach or align connections.

Advantages

The extension pipe offers a precise 250 mm increase in duct length while maintaining a uniform 180 mm internal diameter. Its rigid construction keeps the duct run aligned and reduces the risk of kinks or collapses that can impede airflow. The black finish provides a discreet appearance for visible installations and resists surface wear in normal HVAC environments. Installation requires no special tools beyond standard duct joining methods and produces a predictable, low-resistance airflow path when connected correctly.

Suitable for

• Extending round ventilation ducts by 250 mm to bridge gaps or align components
• Connecting fans, range hoods or ventilation outlets with 180 mm diameter ports
• HVAC repair and maintenance tasks that require a straight rigid segment
• Retrofit projects where a short, standardized duct piece improves fit

Key specifications

• Length: 250 mm
• Inner diameter: 180 mm
• Shape: round, cylindrical
• Finish: black
• Material type: rigid ducting suitable for ventilation systems

How to use

Measure the gap to confirm that a 250 mm extension will provide the required reach and alignment. Slide the extension pipe onto or into the mating duct or appliance outlet with matching 180 mm diameter, ensuring a snug fit. Secure the joint with suitable clamps, duct tape or mechanical fasteners as appropriate for the installation and local regulations. Check for straight alignment and seal any seams to minimize leakage and preserve airflow efficiency.

Usage recommendations

For reliable performance, use the extension with ducts and appliances that have a compatible 180 mm outlet and maintain straight runs where possible to minimize pressure loss. Inspect connections periodically for looseness or damage, and avoid exposure to extreme temperatures or corrosive substances that could compromise the material.
