## Long description

Check valve airRoxy 100 for airRoxy fans model 07-197 is a backflow prevention accessory with a 100 mm diameter connection designed for inline and ducted ventilation systems. The valve prevents reverse airflow when the fan is switched off, helping to maintain intended air movement and reducing drafts. It is compatible with airRoxy fans specified for Ø100 connections and is intended for residential and light commercial ventilation applications.
Advantages
The check valve provides a compact and low-resistance solution to prevent backflow without adding significant pressure loss to the ventilation circuit. Its Ø100 connection ensures straightforward integration with standard ducts and inline fans, and the valve operates automatically without external power or control. The design reduces unwanted drafts and helps maintain indoor air quality by keeping conditioned air from escaping when the fan is idle.
Suitable for
 Inline ventilation systems with Ø100 ducting
 Residential bathrooms, kitchens and utility rooms
 Light commercial ventilation installations requiring backflow prevention
 Replacement or retrofit on compatible airRoxy fan models
Key specifications
 Connection diameter: 100 mm (Ø100)
 Function: passive check valve for backflow prevention
 Intended application: ducted ventilation and inline fans
 Operation: automatic, no external power required
 Suitable environments: residential and light commercial spaces
How to use
Install the check valve inline in the duct run at a point between the fan and the outlet or grille, maintaining correct airflow direction as marked on the valve body. Secure the connection with appropriate clamps or duct tape and ensure a tight fit to avoid leaks. No wiring is necessary; the valve operates by allowing airflow in the fan-driven direction and closing under reverse or zero flow conditions. Follow the fan and duct system manufacturer instructions for placement and support to avoid strain on duct joints.
Usage recommendations
Verify compatibility with your airRoxy fan model and Ø100 ducting before installation. For best performance, place the valve as close to the fan outlet as practicable while allowing access for inspection. Periodically check the valve for debris and ensure the moving parts are free to operate; clean with a soft brush or cloth and avoid aggressive solvents. In systems with high humidity or particulate load, consider routine inspection intervals to maintain reliable backflow prevention.
