Elbow Eliminator - gain 5 foot of duct run Standard dryer exhaust duct-length criteria states that each 90° elbow you install reduces the allowable total length of dryer duct by five feet. Installing The Dryerbox® removes the need for a 90° bend penetrating the drywall, instantly gaining five feet of duct run.
Larger Appearing Laundry Room - Sales Tactic Because customers are so accustomed to seeing the dryer sticking out five or six inches from the wall, installing the Dryerbox® can have a big impact. When they walk through a model home, a keen eye will notice the unusual position of the dryer when it’s moved all the way back. This is a great moment for a sales agent to comment on the innovative, space saving and energy saving devices that you provide and how that attention to detail can be found throughout the house.
Try it! Walk into a laundry room with the dryer pushed all the way back. You will notice and feel the difference.
Dryer Related Service-calls Are Minimized Clothes dryers can be a nuisance when they become callback items for new-home builders. When the flex hose becomes squished, for example, exhaust efficiency is reduced and air movement is not sufficient to carry small particles of lint to the exterior.
Due to this bottleneck, lint will collect in the flex hose and duct pipe until th homeowner notices that clothes are not drying (or until there is a fire). In most cases, the builder initiates an expensive service call only to find that the dryer was pushed back too far and air-flow was restricted. These dryer related service calls can be virtually eliminated with the use of the Dryerbox®. This simple receptacle allows the homeowner to move the dryer as far back against the wall as they desire with no negative effect to the efficient movement of air through the hose.
Clothes Dryer Building Code information (Summary of ICC Codes): 2003 IMC - International Mechanical Code (section 504) and 2003 IRC - International Residential Code (section 1501): In brief, the maximum length of duct permitted is 25 feet. This maximum length should be reduced by 2.5 feet for each 45° bend and 5 ft. for each 90° bend. The maximum length of exhaust duct does not include the transition duct. The duct should be a minimum nominal size of 4 inches in diameter and shall have a smooth interior finish.
