PRESSURIZATION FOR CLEAN ROOMS
When working in a clean room, dust and other unwanted particles in the air must be avoided. To keep them out requires constant pressurization for clean rooms with clean air pumped into the space. The filters become a major expense.
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.
HOW IT WORKS
The Air Cleaning BlowerTM works by pulling dirty 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.
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.
KEY FEATURES
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 especially help in cement plants when keeping the dry cement and limestone dry is a requirement. 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.
TESTING
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 many 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.
Our current models can provide operators of clean rooms with substantial savings in maintenance labor and material costs by prefiltering the air for expensive downstream HEPA and ULPA filter elements to greatly extend their lives and reduce their maintenance. ACBs can also replace separate blower systems because they move and pressurize the air as well as clean it.
We are developing, and expect to offer shortly, ACBs that will consistently remove particles below one micron in size, which will enable users to reduce the costs of operating clean rooms substantially more.
POTENTIAL APPLICATIONS
Pre-cleaning air entering expensive downstream filters
Pressurization for Clean Rooms
Remove rain, mist and snow from air to keep downstream filters dry and prevent their freezing up
Providing more consistent airflow, air pressure and energy consumption by eliminating the clogging of other types of pre-filters
Eliminating the need for separate fans and filters by combining both functions into one compact unit
