The restriction rings are a small but crucial part of the Air Excellent air distribution system. Yet they are often forgotten! They offer many advantages, including saving you time as an installer. But how do they work?
Restriction rings are placed on the inside of an air distribution box. Each ring consists of twelve removable rings. This determines exactly how much air flows through the ducts into a room.
Once you have determined the ventilation capacity for a home and the diameters of the ducts, you then know exactly how many rings you need to remove from the restriction ring to get the right amount of air in each room.
The restriction rings offer several advantages which means you no longer have to adjust the system to the valves, as is traditionally done. All valves can be placed in their maximum open position, meaning that adjusting the system takes much less time. You only have to measure and check the air quantities per room. Using the restriction rings will also result in more satisfied customers as they’ll be experiencing less noise pollution from the rings.
Another advantage is that residents can no longer unknowingly disrupt the system by turning the valves. A problem that many housing associations have to deal with. If you disrupt the system, bad odours, CO2, small particles, and moisture remain in the house. This causes air quality to deteriorate and mould formation may occur.
