Warns of Airflow Restriction
Back pressure in the dryer's exhaust system is always changing. Over time, it increases because of lint buildup, crushed hoses, damaged vent hoods and—surprisingly often—animal nests. The LintAlert® works to protect you by continually monitoring airflow and showing the exact pressure in the exhaust system. Armed with this information, you can save energy and be certain the dryer is operating at safe levels.

Air pressure sensor
The LintAlert gathers this information through a highly discriminating digital pressure sensor. It detects extremely small changes in water column inch (WCI) pressure by sampling minute amounts of airflow. Because of the very small volume of air sampled, there is zero impact to air pressure in the duct.

Onboard Computer
The air pressure samples are then analyzed by a programmable integrated circuit. This small onboard computer evaluates data to know whether the dryer is on and how the exhaust system is performing. Most importantly, it learns each unique system (click here to learn more about computer calibration) so it can compare current airflow to optimal, then report changes over time.

LED Indicators
These changes are shown through a simple to understand LED interface where green indicators, turn to yellow, and then red as pressure becomes more problematic. Optimal performance is shown with a single green indicator glowing. As airflow naturally becomes restricted over time, the second, then third green indicator will illuminate. This is a good time to clean the dryer and duct system for best energy efficiency and safety. In the event the system is not cleaned at that point, the yellow and red indicators will eventually illuminate. Once pressure becomes dangerous (or there is a sudden obstruction) all LEDs flash in unison and an audio alarm sounds. 

DELAWARE DRYER VENTS ONLY USES THE BEST....


Choosing the Right Duct
The dryer's transition hose can be an important factor in saving energy. It can also be a critical factor in protecting property and even lives. Why? Dryer-caused home fires have been documented at levels exceeding 14,000 a year. Flammable lint accumulates quickly in every exhaust system (even those that have the lint filter cleaned with every l...oad). This can create a very real fire danger.
What's going on behind the dryer?
A big problem faced in laundry rooms is the crush point. Dryers naturally vibrate, or get pushed back against the wall. A transition hose that's not built strong (like every duct that was previously available before DryerFlex) can restrict airflow and actually increase the rate of lint accumulation.
The DryerFlex Advantage
UL2158A Listed
File Number E472188

Marking on Product

Constructed with all aluminum ribbon, DryerFlex fire-rated duct is as flexible as "slinky" foil flex yet stronger than semi-rigid aluminum, making installation easier and every laundry room safer. Quite simply, DryerFlex provides the best functionality of the old transition ducts without any of the defects.
DryerFlex always maintains its four inch diameter whether fully extended or compressed. This smooth interior allows the dryer to perform at peak efficiency. It's strong aluminum ribbon protects against crushing and flamespread. Choose DryerFlex for exhaust duct that's safe, efficient and easy to install.
Choose the Highest UL Fire Resistance Class
For safety reasons and added peace of mind, only UL2158A Class 0 listed ducting, like DryerFlex, should be used to connect the dryer's exhaust system (non-listed hose such as that commonly used to vent bathroom fans should never be used). While building code and dryer manufacturers all require a UL 2158A listed transition duct, there are two classes available. It is very common to find Class 1 rated material that is fairly safe but does develop smoke and flame spread at lower temperatures. DryerFlex is the only flexible duct that is Class 0 listed meaning it withstands fire exposure up to 482° with zero development of smoke or fire.
