Replacing AHU filters on a fixed schedule is simple—but it often wastes money or misses the moment performance starts to drop. Wireless differential pressure sensors solve this by continuously measuring the pressure drop across the filter, revealing clogging trends, efficiency losses, and the true end-of-life point. In this guide, we cover how differential pressure data supports condition-based maintenance, reduces energy waste, and improves indoor air quality—while enabling

Maintaining positive pressure is fundamental to contamination control in clean rooms across pharmaceuticals, semiconductor manufacturing, and healthcare. Wireless differential pressure sensors using LoRaWAN and cellular technologies (LTE-M and NB-IoT) provide a modern, low-power, and scalable approach to continuous pressure monitoring. By delivering real-time data, remote visibility, and automated alerts, these IoT solutions help facilities ensure regulatory compliance, prote

Maximize HVAC efficiency and indoor air quality with Ellenex’s NB-IoT technology. This post explores how the PDT2-N differential pressure sensor optimizes air filter performance through real-time, remote monitoring. Discover how to reduce energy costs, prevent equipment strain, and automate maintenance with LPWAN-based IoT solutions. Perfect for facility managers in smart cities and industrial hubs seeking reliable, battery-operated sensors for sustainable building management

Replacing an air filter too early wastes money—but waiting too long quietly drives up energy bills as your HVAC works harder through a clogged filter. In this guide, we break down how to find the “sweet spot” by weighing efficiency loss, filter cost, and labor. We also introduce an IoT-based calculator powered by real-time readings from the Ellenex PDT2 Differential Pressure Sensor, helping you know when to order a new filter and when it’s time to schedule maintenance.
