Frequently Asked Questions

Q: What sizes does this PVC circular wall air vent cover come in?

A: The vent cover is available in three sizes: 75mm, 110mm, and 160mm, making it compatible with a wide range of standard residential and commercial duct pipe diameters.

Q: How does the barb fitting work — do I need glue or screws?

A: No glue or screws are required. The integrated reverse barbs grip the inside of your duct pipe when pressed in, holding the cover securely in place. The barbs are designed to flex inward on insertion and then expand to lock the fitting, so the cover won't pull out easily.

Q: Is this vent cover suitable for outdoor use?

A: Yes. The hemisphere dome shape and 45° downward tilt deflect rain and debris, and the durable PVC material is weather-resistant, making this cover ideal for exterior wall applications including kitchen exhaust fans, bathroom vents, fresh-air intakes, and dryer outlets.

Q: Can this cover be used for both exhaust and fresh-air intake vents?

A: Absolutely. The design suits exhaust applications (kitchen hoods, bathroom fans) as well as fresh-air supply openings. The weatherproof cap helps keep external contaminants out while allowing airflow through the duct.
