Exhaust Vent 180 Stainless Steel SpiroFlex SX-WN180W2, Circular Duct Outlet

SpiroFlex SX-WN180W2 is a 180 mm stainless steel exhaust vent designed for circular duct systems. It provides a corrosion-resistant outlet for residential and light commercial ventilation, kitchen hood exhausts, and HVAC applications. The product is intended to connect directly to 180 mm circular ducts and to ensure reliable air extraction and a long service life under normal operating conditions.

Advantages

The stainless steel construction offers resistance to corrosion and staining, improving durability in humid or grease-prone environments. Its circular outlet geometry matches standard 180 mm ducting for an easy fit and stable joint. The simple design minimizes airflow restriction while providing a robust termination point for exhaust systems, reducing the need for frequent replacement or maintenance.

Suitable for

• Residential ventilation systems with 180 mm circular ducts
• Kitchen hood exhaust outlets
• Light commercial HVAC exhaust applications
• Bathrooms, utility rooms, and other rooms requiring mechanical extraction

When it may not be suitable

This exhaust vent is not intended for use with non-circular or differently sized duct systems; it is specifically made to fit 180 mm circular ducts. It is not a complete fan or damper assembly and does not include active components—if powered extraction, backdraft prevention, or noise attenuation is required, additional devices must be integrated into the system.

Key specifications

• Material: stainless steel (corrosion-resistant)
• Connection diameter: 180 mm circular
• Application: exhaust outlet for ventilation and HVAC systems
• Typical mounting: inline or wall/duct termination depending on installation
• Suitable environments: residential and light commercial interior spaces

How to use

Install the SpiroFlex SX-WN180W2 by aligning the 180 mm circular outlet with the corresponding duct end, ensuring a snug fit. Secure the joint with appropriate clamps, screws, or sealant suitable for stainless steel and duct material to prevent air leaks. Ensure the surrounding structure supports the vent and that the system is free from obstructions before commissioning. Follow local building codes and ventilation standards when integrating this outlet into existing ductwork.

What to consider before purchase

• Verify that your ductwork uses a 180 mm circular diameter for compatibility
• Confirm that stainless steel is suitable for your environment (corrosion resistance and finish)
• Determine whether you need additional components such as dampers, fans, or noise attenuators
• Check installation space and mounting method to ensure proper fit and support

Usage recommendations

For best performance, pair the SX-WN180W2 with properly sized ducting and secure connections to minimize leakage. Regularly inspect the outlet for blockages or grease buildup in kitchen applications and clean as needed. When integrating with powered extraction, include appropriate backdraft prevention and noise control elements to meet comfort and regulatory requirements.
