The Honeywell L404F 1102 Pressuretrol Controller is a robust and reliable control unit designed for automatic regulation of pressure in industrial, commercial, and HVAC systems. Built to Honeywell’s high engineering standards, it precisely controls pressure within a defined range of 10–150 PSI, using a subtractive differential mechanism to ensure smooth system operation. The controller activates or deactivates equipment such as compressors, pumps, or boilers to maintain desired pressure levels, enhancing both performance and safety.
Compact, durable, and easy to install, the L404F 1102 offers stable performance in high-pressure applications. Its subtractive differential adjustment allows fine-tuning of pressure differentials between 10–22 PSI, making it ideal for systems requiring precise control under variable conditions. With a maximum line pressure of 150 PSI, this Pressuretrol is widely used across HVAC systems, industrial compressors, and process equipment. Its rugged design ensures long service life and consistent performance in demanding environments.
