Description
The Honeywell L404F1391 Pressuretrol Controller is a pressure switch that is used to maintain pressure in a system. It works at a pressure range of 20-300 PSI, where it will switch on or off a circuit depending on the set pressure. This snap-action controller makes it possible to respond to pressure changes in a fast and definitive manner. It is widely used in HVAC systems; its function is to safeguard equipment such as compressors and pumps from pressure-related harm. These include; Increased system dependability, increased power utilization efficiency and low equipment maintenance due to avoided failures.
