Wall air inlet 160 mm aluminium SpiroFlex CW160-AL

The SpiroFlex Wall air inlet 160 mm aluminium CW160-AL is a wall-mounted ventilation component designed to provide a controlled external air intake for residential and light-commercial systems. With a nominal diameter of 160 mm, this aluminium inlet connects to circular ductwork to supply fresh or make-up air to mechanical ventilation systems. The aluminium construction offers corrosion resistance and a lightweight profile that simplifies mounting on exterior walls.

Advantages

The aluminium body ensures durability against weather exposure while remaining lightweight for easier handling and installation. The 160 mm nominal diameter matches standard circular duct sizes for straightforward integration into existing ventilation networks. Its wall-mounted design positions the intake externally, reducing the need for extended duct runs and helping maintain efficient airflow into the building’s ventilation system.

Suitable for

• Residential mechanical ventilation systems requiring a 160 mm inlet
• Light-commercial ventilation and make-up air installations
• Retrofit projects where an external wall-mounted air intake is needed
• Applications requiring a corrosion-resistant, lightweight inlet

Key specifications

• Nominal diameter: 160 mm
• Material: aluminium
• Mounting type: wall-mounted
• Application: external air intake for supply or make-up air
• Compatibility: circular duct systems with 160 mm connection

How to use

Install the inlet in an appropriate exterior wall location, ensuring a clear external air path and compliance with local building and ventilation codes. Cut or prepare an opening sized for a 160 mm circular connection and secure the inlet to the wall using appropriate fasteners and sealants to prevent water ingress. Connect the inlet to the building’s ductwork using compatible 160 mm circular duct or transition pieces, and ensure joints are airtight. Position the inlet away from sources of contamination or obstructions that could restrict airflow.

Usage recommendations

Regularly inspect the external inlet for blockages, debris, or corrosion and clean as necessary to maintain airflow. Use suitable exterior-grade sealants and fasteners during installation to prevent water penetration. For best performance, coordinate placement with the ventilation system designer to avoid short-circuiting of supply and extract airflows.
