When installing a tower dryer vent, selecting the proper size of diameter is crucial for optimal performance. An undersized vent can restrict air movement and potentially lead to excessive lint buildup and longer drying times. Conversely, an overly large vent is unnecessary and doesn’t improve function. To choose right, consider factors like the number and type of connected dryers.
The number of Dryers
To start, determine how many dryers will be vented through the tower. The general rule is each dryer requires at least 150 square inches of exhaust area. For multiple Gas or electric dryers produce less moisture than gas models, so 150 square inches each generally suffices for up to four electric dryers bundled together. Gas dryers each need larger 175-200 square inches individually.
The Diameter of Dryers
Next, match the total required exhaust area to recommended tower vent diameters. A single dryer is typically serviced by a 4 inch vent. Two dryers call for either one 5 inch or two 4 inch vents. Three dryers work with a 5 or 6 inch vent. Four electric dryers perform well with either one 6 or 7 inch vent. The biggest 8 inch size handles up to five dryers maximum.
Additionally, longer vent runs increase back pressure, so partially offset this with a slightly larger vent choice towards the upper end of the range. For example, do 6 inches instead of 5 for three dryers if the venting extends 25 feet or further. Also pay attention to any elbow joints in the vent run, which each reduce airflow capacity equivalent to 3 feet of straight venting.
Likewise, high altitude locations over 3,000 feet need to go one diameter size up from the standard recommendation. Thinner air at elevation hampers exhaust, requiring extra vent area to ensure optimal drying. Multistory buildings also call for increased vent sizing since air rises more slowly through multiple stories.
Lastly, don’t forget future-proofing. It’s wiser choosing a vent large enough to accommodate adding one more dryer down the line rather than having to later replace an undersized vent. Proper sizing upfront saves money and avoids installation hassles later on.
By following these guidelines based on specific installation factors, homeowners can be sure to select a tower dryer vent diameter ensuring excellent performance for years of dependable drying. The right vent size means lint is eliminated efficiently while allowing connected dryers to quickly complete cycles.
