What is the maximum angle for dryer venting to avoid excessive lint build-up?

The maximum angle for dryer venting to avoid excessive lint build-up is 45 degrees. This is important because a steeper angle can hinder air flow and allow lint to accumulate in the venting system. When venting at an angle greater than 45 degrees, the chances of lint retention increase, which can lead to blockages, reduced efficiency, and potentially dangerous conditions such as overheating or fire hazards. Keeping the angle at or below 45 degrees ensures that moisture and lint can effectively escape from the dryer and flow through the venting system without getting trapped. This promotes proper ventilation and contributes to the longevity of the dryer and the safety of the home.
