EXPLOSIVE DUSTS IN SAWMILLS
When working in a sawmill or furniture plant, woodchips and sawdust and even explosive dusts are inescapable problems. Cutting, drilling, sanding and other processes in a sawmill or woodworking plant creates a cloud of sawdust. Some activities cause more than others, but controlling those particles is a key need.

Cutting, drilling, sanding and other processes in a sawmill or woodworking plant creates a cloud of sawdust. Some activities cause more than others, but controlling those particles is a key need .
The Air Cleaning BlowerTM (ACB) was developed specifically to remove dust, pollen and other particles from the air in dusty and corrosive environments while eliminating the need for constant maintenance due to clogging filters. After removing most kinds of dusts caused by operations, without using any filter elements or media, the ACBs blows out clean air to your application.
The Air Cleaning BlowerTM works by pulling dirty, dust-laden air into its housing like any other fan would. The impeller inside its housing then spins the air around in a novel, multi-patented way, using the momentum of the particles to separate the dusts and other particles from the air. The ACB then ejects the debris back into the place where it came from, such as a conveyor loading a silo to keep the dust from escaping. The clean air then blows out the other side where you need it. The Air-Cleaning BlowerTM accomplishes all this without any type of filter elements or media that need replacement or other maintenance, which could ignite if explosive dusts are in the air.
OTHER AIR PURIFIERS
Other filters and air purifiers that use filter elements often clog quickly and expensively. This clogging decreases the effectiveness of the fan, increases the amount of energy consumption and requires constant maintenance and repair. In contrast, because the ACB has no filter media to clog, replace or maintain, you can be sure you generate constant air flow, air pressure and steady energy consumption for ventilating, pressurizing or feeding air compressors and other equipment. They can also blow clean air into an evaporative (swamp) cooler.
Another key feature is that the ACBs can remove rain, mist and snow from the air, helping the air stay dryer and reducing the load on any air conditioning, refrigeration or dehumidifying equipment. This can help keep the surfaces and coatings dry to enable better-quality varnish and paint finishes. 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.
An internationally-recognized filter-testing laboratory tested the ACBs to establish independently their effectiveness. The testing found that they remove up to 98%+ of the mass of dust and other particles in the air. The laboratory results show that they remove virtually all particles larger than 10 microns and about 40% of smaller particles down to 3 microns in the air. The smallest particles most people can see are about 50 microns. This level of effectiveness is better than that of most air-conditioning systems, and, in most cases, it would take months for enough dust to accumulate to create an insulating blanket that could overheat a motor or an electric box.
AIR CLEANING BLOWERS AND EXPLOSVIE DUSTS
Originally developed to work in harsh environments such as steel, mining and fertilizer plants, the Air Cleaning BlowerTM can help no matter what kind of wood-working or other plant you operate, even those with explosive dusts. 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.
ACBs can be adapted for use in virtually all types of hazardous environments. Under the NEC code, they can be made for Class I Groups B, C and D Division/Zone 1 or 2, Class II Groups E, F, and G Division/Zone 1 or 2, and Class III Divisions 1 or 2. Hence, they can work safely with hazardous quantities of solvents and dusts in the air.
COMMON APPLICATIONS
