Do you know that PM10 dust in workplaces poses a serious danger to most industries?
PM2.5 and PM10 dust containing heavy metals at industrial facilities poses a great danger. This dust, generated during loading, unloading, and production operations, can cause severe harm to health and the environment, and lead to premature wear and tear of equipment.
Furthermore, a company may face lawsuits and fines.

The best way to prevent dust spread is to install a dust suppression and misting system.
How dust is generated:
Coal dust is the main cause of corrosion in all underground mines. It forms during the crushing and grinding of coal, which triggers a chemical reaction with air and creates an oxidizing environment.
The first to be affected are the steel structures that keep the mine running: conveyor lines, transport galleries, coal transfer chutes, supports, and load-bearing elements. Their deterioration leads to reduced overall structural strength, frequent breakdowns, and increased maintenance and repair costs.
In addition, corrosion raises the risk of accidents, equipment downtime, and poses a threat to worker safety.
Thus, coal dust is not only a byproduct of mining but also one of the key factors contributing to the degradation of mine infrastructure.

The principle of operation of a high-pressure misting system
The main unit purifies water and supplies it under a pressure of 4–6 MPa. Through special nozzles, the water flow changes speed and distribution across the jet cross-section, causing large droplets to break up into tiny particles.
Under the influence of aerodynamic forces, these particles further split into countless droplets with a diameter of 10–20 microns, forming a “fine mist.” A single mist particle can absorb up to 60 dust particles, preventing their spread.
This mist remains suspended in the air, capturing dust particles and converting water from liquid to gaseous state, increasing air humidity and effectively purifying it.

System — "Flying Eagle Dust Reduction"
Dust suppression, environmental control
The Flying Eagle system is widely used in raw material warehouses, factory workshops, road network areas, near stations and ports, coal mines, mining enterprises, as well as in enclosed production facilities.
The system supports configuration of up to 9 time intervals per day and can be controlled via a mobile device. It does not require constant operator presence.
The intelligent platform is equipped with notifications for filter replacement, oil changes, and other consumables.

The intelligent platform is equipped with notifications for filter replacement, oil changes, and other consumables.
According to test results and practical application, the Flying Eagle system can effectively reduce airborne dust concentration in an area by 80%–90%.
It generates a large number of micron-sized water droplets that adsorb dust particles in the air, providing a significant dust suppression effect, especially in large open spaces.
Depending on specific requirements, the system can be individually programmed and configured for different operating modes.

Advantages of misting systems
The misting system has proven itself as a reliable dust suppression method. Its advantages include:
-
Ease of useThe droplet size of the mist is approximately 10–20 microns (0.01–0.02 mm), which is smaller than in most other methods — for example, with water cannons or sprinkling, which can actually raise dust back into the air. This reduces labor costs, as the system does not require constant personnel involvement — unlike traditional methods, where two people must operate each nozzle and simultaneously monitor the process. -
SafetyThe water used in the system is safe for people and the environment. The fine droplet size reduces splashing on workers or nearby objects. Compared to methods such as rough cleaning or mechanical sweeping, there is no eye irritation and no health risks, since operators do not come into contact with toxic substances (such as chlorine-based bleaches, ammonia, hydrochloric acid, boron minerals, etc.) that are sometimes used for dust suppression. -
DurabilityThe design of our systems allows them to operate continuously for several years with minimal maintenance costs, unlike mechanical systems. Stainless-steel nozzles with swivel joints ensure easy servicing. -
EfficiencyDust suppression through misting achieves results that are difficult to reach with other methods. The system reduces dust levels and creates comfortable working conditions. The effect becomes noticeable within just a few minutes or hours after activation (depending on weather conditions). -
Low water consumptionThe system provides optimal pressure across the entire spray height, allowing coverage of areas from 500 to 4,000 m². Water consumption is adjustable from 100 to 1,600 kg/h depending on the task. At the same time, hourly water usage can be as low as 2.5 liters per nozzle — significantly lower than that of standard systems. -
Minimal maintenance costsAfter installation, the system requires very little maintenance and has fewer components than most types of dust suppression equipment. There are no meshes, hoses, or complex fittings as in watering machines. -
Low operating costsMisting systems operate more economically than, for example, spraying with lime or water. The fine droplets do not wet or damage equipment, tools, or materials, allowing work to continue without delays. -
Unlimited scope of applicationThe systems can be used both indoors and outdoors, providing flexibility and minimizing work interruptions. -
Instant resultsWhile other methods may require up to 24 hours for the air to clear, with a misting system the results are visible in less than an hour. -
No residual contaminationUnlike chemical dust suppressants, the system leaves no residue that could damage equipment or cause malfunctions.
