When working in a truck, excavator or dragline in a mine or tunneling operation, dust and other unwanted particles in the air are inescapable problems. Opening a door to climb in or a window for air or in fact, any kind of ventilation is likely to bring in unwanted dust and particles and cause harm to the operator. And potentially worse, the equipment’s electrical motors and controls may not be sealed up or pressurized and they accumulate blankets of dust that can cause overheating. Some activities let in more dust than others, but more often than not controlling that dust is a key need of any heavy machinery operation. It seems like a simple fix to blow in clean air; however, having clean air readily available all the time is no easy task, especially in a dirty environment such as a tunnel or mine.
The Air Cleaning BlowerTM (ACB) was developed specifically to remove dust, pollen and other particles from the air in dusty and harsh environments while eliminating the need for filter maintenance due to clogging filters. After removing most kinds of mining and tunneling dusts, without using any filter elements or media, the ACBs blow clean air into your operator’s cabin, engine or electrical-controls area, exactly what it is needed.
The Air Cleaning Blowers work by pulling dirty air into their housings like any other fans would. The impeller and housing are specially designed to use the momentum of the contaminants to separate them from the air (or almost any other gas) and fling them toward the outside of the housing and eject them, most commonly back into the atmosphere from where they came. The clean air continues toward the application for ventilation or pressurization. ACBs accomplish all this without any type of filter elements, sheets, cartridges, bags or other media to maintain.
Perhaps more important, particularly to designers of the systems: when ACBs supply the air moving and air cleaning, they eliminate the fluctuations in airflow, air pressure and power consumption, which makes it much easier to predict and calculate the air-systems’ performances, and therefore, to design optimal systems.
Another key feature is that the ACBs can remove rain, mist and snow from the air, helping the air and protected equipment stay dryer and reducing the load on any air conditioning, refrigeration or dehumidifying equipment. In addition, because there is no filter media catching that rain or snow there is nothing that will become wet or freeze up and prevent the air from passing through.
In addition, ACBs can pressurize the spaces so that air will flow out of the heavy machinery or vehicles and help prevent dusts and sand from blowing in. That pressurization will help protect computers and other electronics, as well as electrical equipment, controls and operators. Since they do not collect the debris, ACBs will not create dangerous hot spots in the filter media if there are hazardous particles in the surrounding environment. Further: all ACBs can be adapted for use with virtually any explosive or flammable gas or dust, Division/Zone 1 or Division/Zone 2.
Our ACBs were tested independently at an internationally-recognized filter-testing laboratory to establish their effectiveness. The testing found that standard models remove up to 98%+ of the mass of dust and other particles from the air. The laboratory results show that they remove virtually all particles larger than 10 microns and about 40% of the particles down to 3 microns from the air. The smallest particles most people can see are about 50 microns. Models under development will consistently remove sub-micron contaminants.
Originally developed to work in harsh environments such as steel, mining and fertilizer plants, the Air Cleaning BlowerTM can help protect mining machinery and other heavy equipment and vehicles you have, wherever you use them. Our ACBs are so effective that they are being used today by the US Military in the Middle East to keep air conditioners cooling, even in sandstorms.
