About this item
  • The airflow-operated gravity shutter is a vent designed to resist rain and weather, and it comes in a sleek white finish. Crafted from premium quality plastic, this item boasts external dimensions of 7.48" x 7.48" / 190 x 190 mm, with a duct connection size of 4" / 100 mm for outdoor applications.
  • Vent Cover serves multiple purposes and can be integrated into a lengthy ductwork system for various applications. These include whole-house ventilation, conditioning ducting, passive ventilation, positive input, HVAC, heat recovery systems, and as a cover for bathroom and kitchen air conditioning fans.
  • The grille features four non-return gravity flap outlets that allow air to flow out. Its shutter mechanism operates by opening the blades to facilitate the passage of air. When the extractor fan or ventilation system is not in use, the shutter flaps close automatically.
  • Cover shutter flaps serves to shield your ventilation duct from unpleasant odors, noise, backdraft, rain, wind, snow and the entry of objects or pests during periods of inactivity
  • Installation is both simple and secure. Just push-fit the duct and fittings together. The Gravity Grille features pre-drilled holes for screwing and attaching it to the wall, ensuring a stable fixation at the ventilation outlet's end. Screws are included.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
