Plymovent AeroGuard - Air Quality Monitoring System

Packed with advanced tech, the AeroGuard measures eleven pollutants and climate factors — all in one compact device. It monitors:

• Particulate matter (PM1, PM2.5, PM4, PM10)
• Volatile Organic Compounds (VOCs)
• Carbon Dioxide (CO₂)
• Temperature
• Humidity
• Sound
• Atmospheric pressure
• Indoor Air Quality Index (IAQ)

Smarter insights, faster decisions

AeroGuard isn’t just about real-time air quality monitoring — it’s about giving you the tools to take action. With the free mobile app (iOS & Android), you get instant insight into your air quality.

Custom calibration: trust your data

What sets AeroGuard apart is its ability to be custom calibrated. While it includes pre-set factory calibrations for general dust, welding fumes, and diesel emissions, you can also fine-tune it for your unique environment. This is especially valuable if you’re already conducting external air tests — AeroGuard can align with that data to deliver more accurate readings tailored to your operations.

Our air monitor measures the presence of particulate matter in μg/m³. This can be e.g. soot particles from the combustion of gasoline or diesel or welding processes in the metalworking industry.

A unique feature of the AeroGuard is that next to default calibrations for general, welding and vehicle exhaust fumes, you have the opportunity to custom calibrate the dust sensor.

The power of this function cannot be under estimated. The large majority of dust sensors are calibrated for general dust. Once used in an industrial environment, like a welding shop, the readings can be off by a factor of 2 to 4. The default factory calibration for welding fume enhances the accuracy already significantly and is a good setting for monitoring, trend lines and deviations. For the highest possible accuracy the AeroGuard can be custom calibrated for your specific environment.

Volatile Organic Components

Volatile organic compounds (VOCs) are gases emitted from a variety of materials that can have short- and long-term health effects. Indoor concentrations of VOCs can be higher than outdoors, especially in workshops where they work with glues, plywood or metalworking fluids. AeroGuard measures the concentration of the Total of Volatile Organic Compounds (TVOC) in mg/m³.

Temperature and humidity

Levels of temperature and humidity are important for the comfort of your employees. AeroGuard measures the temperature in degrees Celsius and degrees Fahrenheit. The humidity is measured in Relative humidity %

Carbon dioxide

If levels of carbon dioxide are too high it can affect people’s cognitive function and decision-making performance. Keeping an eye on this metric is therefore important. AeroGuard visualizes this metric in ppm.

Indoor Air Quality

The German Environment Agency (Umweltbundesamt or UBA) has developed a scale of 1 to 5 for air quality levels. The lower the number, the better the air quality. AeroGuard shows the value in the app.

Atmospheric pressure

AeroGuard shows the atmospheric pressure level in hPa. There can be a difference in pressure between indoor and outdoors. Some people can be susceptible for this change and can experience physical discomfort. But also for businesses keeping an eye on the atmospheric pressure can be of value. When the indoor air pressure is lower than outside, in Summer it can draw in warm air from outside leading to higher costs, as the cooling systems uses more energy to cool the workshop to the desired temperature down again.

Sound pressure level

AeroGuard visualizes the equivalent continuous sound level as LA_eq in dB. This enables you to identify possible sound pollution and initiate actions to reduce them, enabling you to make the workshop even more comfortable for your staff to work in.

The AeroGuard Air Monitor combines style and strength. With its sleek black design, durable build, and high-quality materials, it's made to last — and to look good while doing it. Setup is quick, maintenance is minimal, and using it is as simple as plugging it in.

This compact air monitor fits right into your workspace. Mount it on a wall, place it on a surface, or use a tripod for flexible air monitoring across multiple locations. Want to track indoor air quality in different zones? No problem. You can connect multiple AeroGuards in the same app or web portal for a full overview.

Built for a better future

Sustainability is built into every AeroGuard. Its housing contains 46% post-consumer recycled plastic, and the packaging is completely plastic-free. So while you're improving your indoor air, you're also reducing your environmental footprint.

Stay on top of your indoor air quality monitoring with AeroGuard’s easy-to-use tools. Whether you prefer the free mobile app or the powerful web portal, you’ll get instant access to real-time data through clear visuals and colorful graphs — helping you make fast, informed decisions.

Free mobile app
The AeroGuard app (iOS and Android) puts indoor air monitoring in your pocket. It displays real-time data from all sensors and gives you 24/7 access to your air quality history — right from your smartphone or tablet. The app supports multiple users and makes it easy to track trends over time for any workspace.

Advanced web portal
Looking for deeper insights? The AeroGuard web portal offers full access to detailed metrics and long-term data storage, viewable from any browser. Upload your factory floorplan, divide it into zones, and monitor the indoor air quality in each area in real time. It’s perfect for larger facilities or shift-based operations, with more user access and advanced features like sensor health monitoring and custom settings.

All your data in one place
Connect your AeroGuard to MyPlymovent.com and centralize your air monitoring data. The platform offers seamless integration with Plymovent tools like ControlPro Connect and the Extranet, giving you a complete overview of your clean air systems in one secure environment.

The AeroGuard Air Monitor is the perfect addition to your existing filtration system — providing real-time environmental data that helps you stay ahead of potential risks. It tracks a wide range of pollutants and climate factors, including particulate matter (PM1, PM2.5, PM4, PM10), VOCs, CO₂, temperature, humidity, sound, atmospheric pressure, and delivers a clear air quality index (IAQ) to help you understand what’s really happening in your indoor environment.

Support smart facility management

Accurate air quality index readings are a crucial part of maintaining your HVAC system and overall building health. With AeroGuard, you can detect hidden indoor air issues early and ensure compliance with health and safety regulations — especially in demanding environments like garages, fire stations, metal workshops, production lines, and laboratories.

Visualize how pollutants spread

Airborne pollutants don’t stay in one place. They often move from shop floors or garages into office spaces via doors, stairwells, and ventilation shafts. The AeroGuard makes these movements visible with detailed environmental data, so you can take targeted action to protect your entire facility.

Built for tough environments

Whether you’re monitoring an industrial production hall or a location with indoor vehicle exhaust emissions, the AeroGuard delivers the clarity and precision you need to improve air quality index levels and create a healthier workplace.
