FAQ — BMair Air Filtration Systems
What is a BMair pressurized air filtration system and why is it needed?
A BMair system is a filtration device installed on the cab of heavy equipment that creates a slight positive air pressure inside the cabin. This principle is essential: by maintaining an air pressure slightly higher than the outside environment, the system physically prevents contaminated air from entering the cab, even through small gaps or openings. Operators continuously breathe filtered air without needing to wear a mask, regardless of contaminant levels outside.
What types of contaminants does the BMair system filter?
BMair offers solutions adapted to each type of contaminant. HEPA (High Efficiency Particulate Air) filters capture fine particles such as silica dust, fibers, and asbestos dust — substances that, even at low concentrations, can cause serious lung diseases after prolonged exposure. For environments where gases, toxic vapors, or odors are present (waste treatment, soil remediation, mining sites), activated carbon filters can be added as a complement. The principle is simple: a dedicated solution for every environment.
What are the real risks for an operator working without cab filtration?
Without a proper filtration system, heavy equipment operators are exposed daily to serious respiratory risks, the effects of which often appear years later. Crystalline silica found on demolition sites, in mines, and quarries can cause silicosis — an irreversible lung disease. Long-term exposure to fine dust is also associated with lung cancer and chronic obstructive pulmonary disease (COPD). These risks are especially high during peak concentration moments, such as loading or dumping materials.
What is the difference between the BMair MAO-3 Cab Guard and the BMair Protector?
Both systems are based on the same positive pressure principle but are designed for different applications.
The BMair Protector is the economical solution for filtering fine particles such as silica dust, fibers, and asbestos dust. Compact and connected, it features a HEPA filter and an intelligent system that automatically manages pressure and monitors filter status in real time from inside the cab.
The BMair MAO-3 Cab Guard is the most advanced solution when odor control and contaminant management require activated carbon filtration combined with fine particle filtration. It is also the preferred solution for the most demanding environments, where BMair has built its reputation for purifying air in conditions where other systems fail.

How does the BMair system know when filters need to be changed?
One of the key innovations of the BMair range is that all filters are equipped with RFID chips. The in-cab display continuously shows the type of filter installed and its estimated remaining service life. Operators or health and safety managers no longer need to open the system to inspect the filters — a process that itself can expose them to contaminants. This automatic identification also ensures that the correct filter is used for each machine and environment. Every BMair system includes cellular connectivity and free access to the BMair web portal throughout the life of the system.
Is the BMair system compatible with my machine?
Yes. BMair offers solutions adapted to virtually all types and brands of heavy equipment: excavators, wheel loaders, forklifts, dump trucks, graders, drills, garbage trucks, municipal vehicles, and many more. The systems are designed to be compact enough to fit modern machine cabs, which are increasingly space-constrained. RMT Equipment, the exclusive distributor in Canada, performs a compatibility evaluation before every installation.
In which industries is BMair most commonly used?
BMair is widely used in industries with high exposure to airborne contaminants:
- Mining and quarries: silica dust, asbestos dust, crushed rock
- Demolition and construction: concrete particles, asbestos, fibers
- Soil remediation and decontamination: toxic gases, chemical vapors
- Recycling and waste management: organic particles, odors, ammonia
- Municipal sector: roadwork, compaction, waste collection
Does using BMair help meet occupational health and safety regulations in Quebec & Canada?
Yes. Canada & Quebec’s Occupational Health and Safety Act (LSST) requires employers to ensure the quality of the air breathed by workers. In contaminated environments, a certified cab filtration system represents a documented preventive engineering control recognized by authorities such as the CNESST. In the event of an audit or inspection, demonstrating that your machines are equipped with approved filtration systems strengthens compliance and reduces legal liability exposure.
Does working with a BMair system mean the operator no longer needs to wear a mask?
A properly installed and maintained BMair system, combined with a well-sealed cab, effectively allows operators to work without a respiratory mask. This is one of the most appreciated benefits in the field: operator comfort improves significantly, which also promotes better concentration and reduced fatigue.
Is RMT Equipment the BMair distributor in Canada?
Yes. Since 2025, RMT Equipment has been the Canadian partner of BMair International BV. Based in the Netherlands, BMair has been developing its systems for over 30 years and is globally recognized for the quality and reliability of its technology. RMT handles sales, installation, calibration, and technical support for all BMair systems in the industrial, mining, and municipal sectors across Quebec and Canada.
