5. ഓപ്പറേഷൻ
The AF4 vent cover operates passively, utilizing its internal damper system to regulate airflow and prevent backdrafts. The design allows for both exhaust and air intake applications.
Exhaust Application
When used for exhaust (e.g., dryer or bathroom fan), the internal damper opens to allow air to exit and then closes securely when the fan is off. The triple-sealed and insulated damper helps maintain indoor temperatures by preventing cold air from entering and warm air from escaping.
Air Intake Application
The back-draft damper can be converted for air intake applications, such as for air exchangers. In this configuration, the damper allows fresh air to enter while still providing protection against elements and intruders. The removable galvanized steel bird screen remains effective in both modes.

7. പ്രശ്നപരിഹാരം
If you encounter issues with your vent cover, refer to the following troubleshooting tips:
| പ്രശ്നം | സാധ്യമായ കാരണം | പരിഹാരം |
|---|---|---|
| കുറഞ്ഞ വായുപ്രവാഹം | Blocked bird screen or damper. | Remove and clean the bird screen. Check the damper for obstructions and ensure it moves freely. |
| Damper Not Closing Properly | Debris obstructing the damper, or damper mechanism damage. | Clear any debris. If damaged, contact customer support for assistance. |
| Noise (e.g., banging in wind) | Strong winds causing damper to flap, or improper installation angle. | Ensure the vent cover is securely mounted and sealed. Verify the installation angle; some vents perform better with a slight upward tilt to prevent wind-induced flapping, though this may affect moisture drainage. Consult a professional if issues persist. |
| Water Infiltration | Improper sealing during installation, or damaged stormproof deflector. | Re-check sealant around the pipe and flange. Inspect the stormproof deflector for damage. |
