A four-piece grill sound attenuating product that screws together in a door for any room that requires improved ventilation with some extra air flow.  See also the Smaller QVENT Design. above.

This door vent will significantly improve the performance of an axial exhaust fan to remove humidity and odors from a room and reduce the likelihood of mold growth.

In many cases Bathroom and Toilet fans cannot get of enough air to move through the fan. With air coming from down low in a door, humidity and smells move quickly and efficiently outside via your ceiling fan.

At Efficiency Matrix we take air flow quite seriously, so we measured the actual flow rates within an average bathroom with a single ceiling fan. With a door vent fitted, the flow of air up and out of the ceiling fan is increased by 33%.  The substantial increase in air flow as a result of a door vent can improve air quality and thus lessen the incidence of mold.

Ducted heating systems can become unbalanced when the supply vent in a home is not able to get back to the return vent.  This happens when doors in the home are kept closed.  The best way to solve this problem, is to let the air get back via a door grill.

There is a smaller version of this Aussie made product and developed acoustic sound attenuating door vent product called qVENT Type 3. Link Below
