LEFOO's differential pressure (DP) switches provide accurate and reliable monitoring of pressure differences across filters, enclosures, ducts, and process lines. Designed for critical applications in HVAC, industrial machinery, and cleanrooms, they ensure system efficiency, protect equipment, and maintain safety by triggering alarms or control actions at precise set points.
Filter Status Monitoring: Automatically alerts for filter replacement in air handling units (AHUs) and exhaust systems, optimizing maintenance schedules and ensuring air quality and energy efficiency in commercial buildings.
VFD Fan Control & Duct Pressure: Provides a control signal for variable frequency drives (VFDs) to maintain constant air pressure in ductwork, crucial for laboratory ventilation, cleanrooms, and data centers.
Filter & Strainer Monitoring: Protects pumps and sensitive instruments by detecting clogging in liquid and gas filtration systems across water treatment, chemical processing, and manufacturing plants.
Fluid Flow Verification & Safety Interlocks: Used as a flow switch alternative to confirm coolant/lubricant flow in machinery or to ensure proper sealing in hazardous area enclosures (purge systems), preventing costly downtime and safety hazards.
