Overview

PMDuct is an in-duct solution for continuous real-time particulate matter monitoring within HVAC and clean air systems. Designed with the NextPM Advanced sensor inside, it provides accurate PM1, PM2.5, and PM10 measurements in both mass and particle count, while resisting humidity effects and enabling filter performance tracking. With Modbus RTU connectivity and easy integration into building management systems, PMDuct helps optimize maintenance, energy efficiency, and air quality compliance.

Key Features

Continuous In-Duct PM Monitoring:

PMDuct continuously measures particulate matter (PM1, PM2.5, PM10) in ventilation ducts and HVAC systems, delivering both mass concentration (µg/m³) and particle count (pcs/L) with high repeatability and reliability.

Built-In NextPM Advanced Sensor & Integration:

Equipped with the NextPM Advanced sensor, PMDuct resists humidity effects, tracks filter performance, detects duct clogging, and integrates easily with building management systems via Modbus RTU for seamless environmental monitoring.

Benefits

Improved Air Quality Monitoring

Real-time, accurate particulate data helps facility teams maintain cleaner air in HVAC systems, reducing contamination risks and enhancing occupant comfort.

Enhanced System Performance & Maintenance

By tracking filter performance and identifying clogging early, PMDuct supports proactive maintenance planning, extending equipment life and optimizing energy use.

Compliance and Operational Confidence

Continuous in-duct monitoring supports regulatory and internal compliance with air quality standards while providing actionable data for environmental and facility management.

FAQs

PMDuct measures particulate matter concentrations — PM1, PM2.5, and PM10 — in HVAC and ventilation ducts, providing real-time data in micrograms per cubic meter and particles per liter.

Yes. PMDuct offers Modbus RTU connectivity to integrate seamlessly with building management systems and other environmental monitoring platforms.

By tracking filter performance and detecting clogging through changes in particulate counts, PMDuct enables proactive maintenance that can reduce downtime and improve HVAC efficiency
