LSS – Laundry Exhaust and Supply Air System

The LSS combined the Laundry Exhaust and Supply Air Systems to maintains a constant pressure in the laundry exhaust system and a constant pressure in the mechanical room or ducted supply through a single control panel. Designed with EC-Flow Technology™, the LSS 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 clothes dryer exhaust system while rapidly respond to varying outdoor pressures to maintain a neutral pressure in the mechanical room or appliance inlet duct when compared to atmosphere. 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 LSS meets all requirements for the National & International Fuel Gas Codes and the Uniform & International Mechanical Codes.
