Trolex Air XD Dust Monitor

The Trolex Air XD Dust Monitor provides a continuous picture of airborne respirable dust, turning invisible particulate hazards into precise, real-time data. Instant visibility of dust levels enables rapid intervention when concentrations rise, helping prevent over-exposure and support protection against long-latency occupational diseases such as silicosis, black lung and COPD. By underpinning evidence-based health and safety management, it helps duty holders demonstrate adherence to permitted exposure limits and other regulatory dust requirements.

Rather than reporting a single dust value, the Air XD delivers detailed insight across the full spectrum of harmful particulates. A high-capacity optical particle counter and advanced sensing algorithms separate particles into 24 size bins, supporting granular profiling of workplace environments. Standard PM size fraction reporting, including PM1.0, PM2.5, PM4.25, PM10 and Total Suspended Particulates (TSP), aligns monitoring with recognised occupational hygiene frameworks. Custom particle size categories can also be defined, enabling application-specific monitoring tailored to different processes, materials and risk profiles.

The Trolex Air XD Dust Monitor is designed to overcome the limitations of traditional particulate monitors in high dust environments. It delivers dust concentration measurements to within approximately

±5% accuracy, maintaining performance even in extremely high dust loads of around 1500 mg/m³. Operational stability in harsh, high dust and hazardous industrial settings supports confident use of the data for critical safety and process decisions. A compact, rugged IP66 stainless steel enclosure resists challenging conditions and makes the unit suitable for both fixed installations and transportable area monitoring.

An open-path optical particle counter design with no filters, no pumps and no moving parts significantly cuts routine maintenance and consumable requirements. Extended maintenance intervals of approximately 6–12 months are achievable, helping reduce service visits and downtime compared with many traditional systems. Rapid in-field calibration can be completed in seconds without laboratory testing or returning the unit to base, streamlining ongoing validation. Configurable particle flow path options, including open or closed caps, allow the detector to be optimised for different environmental conditions while maintaining consistent performance.

The Air XD supports both permanent and temporary monitoring strategies. It can be installed as a fixed detector to track high-risk areas continuously, or deployed in a transportable pack for rapid redeployment across different locations. Wide power input options, including 100–240 V AC and 9–36 V DC variants, provide flexibility across sites and regions. Plug-and-play installation, straightforward commissioning and the absence of complex calibration routines help minimise installation effort and speed up deployment on new or existing sites.

A high-visibility local display shows real-time respirable dust levels directly on the unit, with selectable modes for live readings or averaged values over defined time periods. On-device indicators provide at-a-glance confirmation of system status and alarm conditions, helping workers recognise hazardous dust levels instantly. Fully programmable alarm thresholds, including time-weighted average alarms from 1 second to 24 hours, support both short-term event detection and long-term exposure management. Instant alarm functionality can trigger timely use of PPE or RPE, changes to working practices and adjustments to ventilation or extraction systems.

The Trolex Air XD Dust Monitor integrates readily into modern control and safety architectures. Communication interfaces including RS485 Modbus RTU and Ethernet Modbus TCP/IP support connection to SCADA, DCS and other site systems. Two 4–20 mA analogue outputs transmit measured average dust concentrations to control equipment, while two configurable relay outputs can drive remote alarms or automatic activation of ventilation, extraction or suppression systems. These integration options enable more targeted use of engineering controls, supporting reduced energy consumption and lower operating costs while maintaining safe dust levels.

Integrated data logging stores particulate measurements and event history, creating a detailed record of dust exposure over time. Live and historical data can be viewed remotely via companion software platforms such as Breathe XD and AIR X Software. A centralised dashboard allows trend analysis, comparison of different areas and real-time configuration of multiple units across a site or network. This digital record supports regulatory reporting, underpins continuous improvement in dust control strategies and can help protect organisations against future litigation by documenting historical exposure levels.

Suitable for sectors such as mining, construction, manufacturing and other hazardous industrial environments, the Trolex Air XD Dust Monitor is built for continuous, 24/7 operation without disrupting normal work processes. It provides full-spectrum particulate information to identify process leaks, optimise suppression, extraction and ventilation systems, and support ongoing process development. Available in certified Group I versions for explosive and hazardous areas and backed by a global Trolex distribution and support network, it offers a robust platform for long-term dust monitoring strategies. Extended warranty options of up to three years provide additional assurance and help plan predictable lifecycle costs.
