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.
