LES – Laundry Exhaust System

The Laundry Exhaust System (LES) maintains a constant pressure in the laundry exhaust system. Designed with EC-Flow Technology™, the LES takes advantage of LFSystems. bi-directional pressure transducer and proprietary PID technology to rapidly respond to varying manifold pressures due to load changes in the laundry exhaust system. Utilizing the Truline™ DEF Dynamic Exhaust Fan and an L-series control, the system can receive a start signal through a current sensing relay or may run continuously. The LES meets all requirements for the National & International Fuel Gas Codes and the Uniform & International Mechanical Codes. The Laundry Exhaust System also offers available in-line lint collectors which can alert the controller when the filter bag is full and extend the life of the system by up to 50%.
