FPS-L Series (HVAC/R) Liquid Level Sensor
The FPS-L Series is a low-profile flood prevention switch designed for HVAC/R systems, offering reliable protection against condensate overflow. Engineered for compact installations, it automatically shuts off air conditioning systems when water levels rise due to clogged drain lines—helping prevent damage to ceilings, walls, and floors.
Its slim design allows for easy mounting directly to the side of the drain pan, making it ideal for tight spaces and retrofit applications. The FPS-L Series complies with UL508, NEC, and IMC standards, ensuring dependable performance and code compliance in both residential and commercial HVAC systems.
