Laundry Exhaust Systems


The Laundry Exhaust System (LES) maintains a constant pressure in the laundry exhaust system. Designed with EC-Flow Technology™, the LES takes advantage of US Draft Co. 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™ MEF Multi-use Exhaust Fan and an L-series control, the system can receive a start signal through a current sensing relay or may run continuously.
