Testing Foil Flex
The LintAlert monitoring system has undergone extensive testing to cover myriad different exhaust configurations including foil flex transition hose as shown.
Dryer system exhaust pressures vary greatly among major manufacturers as do the length and restrictiveness of the in-wall duct systems. The command module includes a smart computer that samples optimum back pressure, makes sure that it is within general safety parameters and delivers different feedback depending on the unique exhaust of every dryer.
Lab testing has confirmed that the LintAlert is effective with most all configurations. The exceptions being only dryers with dual motor technology (rare and declining in use) and dryers that share exhaust systems like those found in high-rises.
