Dust Suppressors – Types And Usage In Construction Site


Dust in construction sites is unavoidable. As such it poses a significant health hazard to your workforce. Fortunately, there are measures you can put in place to help reduce or eliminate its effects on your workforce and your worksite. The most effective way to do so is by employing efficient dust suppressors like those by Bosstek. Even then, although dust suppressors have a similar end goal, they’re different types available on the market for dust control in specific areas around the various construction activities. Let’s explore them and find out more.

Types of Dust Suppressors

Misting Cannons

Misting cannons feature high portability in dust control. They come mounted on wheeled trailers that enhance quick and easy on-site positioning. Therefore, they’re highly efficient in outdoor dust suppression around the construction site. Additionally, the machines’ designs enable them to convert water into the atomized mist – a cloud of fine water droplets ranging from 50 to 200 microns. The range is perfect for capturing dust particles effectively and bringing them to the ground.

It’s worth noting that when the droplets are too large, the slipstream effect occurs, resulting in the dust avoiding suppression. On the other hand, too tiny droplets lack enough weight to enable the dust particles to fall to the ground. Therefore, misting systems are efficient because they release the droplets in just the right size. In general, misting technology facilitates economical water usage. This in turn helps lower your water bill during the construction project.

Dust Collection Systems

Unlike misting suppressors, dust collection systems do not use water in dust control. Instead, they draw the dust from a designated area by suction. The dust is collected in a specific chamber for separation from the ongoing construction activities. Powerful fans and ducting processes enhance the suction process.

What’s more, the machines function best when the dust can be channeled in a specific direction. That means dust collection systems are not viable in controlling multi-directional dust like that generated during demolition processes. Therefore, they are limited to certain construction activities. For the most part, they’re used indoors. Additionally, since the collected dust is stored in a specific chamber within the machine, frequent emptying and dumping are necessary.

Nozzle-Based Fogging Systems

These equipment are fixed solutions in dust control. They feature a permanent installation of metal pipes that route water from high-pressure pumps and directs it to the nozzles. Then, the nozzles convert the water into fine droplets before releasing it into the air for dust suppression.

Similar to the misting cannons, nozzle-based fogging systems effectively capture dust and bring them to the ground using a fine cloud of water droplets. The difference between the two is that you can easily relocate the former from one area to another. For the nozzle-based fogging systems, you can only use them in fixed locations to control dust.

Uses Of Dust Suppressors in a Construction Site

Dust suppressors play a crucial role in construction activities like when demolishing old buildings, grinding activities like polishing floor surfaces, rock drilling, and stone cutting, mixing of concrete and cement which usually releases fine dust particles in the air, or mining activities

In every construction site, dust control machines come in handy as they help you control dust and minimize its effects on both your workers and construction equipment.
