LFSystems Laundry produces exhaust and combustion air products.
Dryer Exhaust
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. Learn more
