3 Things to Consider When Selecting a Dust Extraction Unit

In order to provide and maintain a healthy and safe working environment in industries the quality of air inside the working area has to be improved by using dust extraction solutions.  Harmful dust particles and fumes that are generated from various industrial operations mix with the surrounding air and pollute the environment thereby posing health hazards for workers that can also affect productivity. Installing dust extraction systems is the only way to control and manage effectively dust particles and fumes. A dust extraction system is equipped with powerful extractors that suck particles floating in the air and arrest it inside the system thereby providing a cleaner air within the work area. The extraction system does not work in isolation but is a part of the ventilation system that takes into consideration the dynamics of air flow that carries air borne pollutants and particles throughout the facility.

Dust extraction systems are designed by blending engineering expertise and the knowledge about maintaining proper air quality. Understanding the basic operational technology helps in selecting a system that would be convenient to install and safe to operate. Techno-commercial considerations play a dominant role in the process of selection of dust extraction systems. The most important points that should be considered during the selection of a dust extraction system have been discussed in this article.

Know the technology basics

The efficiency of a dust extraction system depends on the quality of filters and how clean it is.  Filter cleaning in most dust collectors is done by shaking off loose dust from its surface and collecting it in bins. Shaking off the dust particles is achieved by a process called pulse cleaning that involves air pulses being blasted on filters. While this operation is happening, simultaneously there is possibility of the dust finding its way back into the filters due to the air flowing constantly through the collector despite the dust particles that have been collected in the bin. To overcome this problem, look for dust extraction systems that use more advanced electronic pulsating technology  for each filter that operates on double pulse action  sequentially so that chances of particles re-entering the filter is eliminated. Filters that are placed vertically are likely to reduce the possibilities of re-deposit of particles.

Compact system

Look for a system that is compact in design – a cabinet houses all the components of the system that includes the blower, motor, filters, safety features, containment unit and control panel. This makes installation easy and cheap as only compressed air and electricity connections are required at site. Pre-shipping inspection of such units that are already assembled is also easy.

Safety features

The cabinet has to be completely sealed so that there is no leakage from the welded joints and seams. In some advanced models, sensors are used to detect leaks and automatically shut down the system so that the harmful elements from the collector do not re-enter into the environmental air. Fire suppression systems are also provided in some models.
