When working in a greenhouse or hothouse, dust and pollen are inescapable problems.  Planting seeds, spraying pesticides, sowing dirt, or watering plants, somehow there is always a cloud of dust, extra particles or an excess of air droplets in the air.  Some activities cause more than others, but more often than not controlling those particles  and properly ventilating greenhouses is a key need of greenhouse operations.

The Air Cleaning BlowerTM (ACB) was developed specifically to remove dust, pollen and other particles from the air in dusty environments while eliminating the need for constant maintenance due to clogging filters.  After removing most kinds of greenhouse particles and other dusts, without using any filter elements or media, the ACBs blows out clean air to your application.



Air Cleaning BlowersTM (ACBs) work by pulling dirty air into their housings like any other fans or blowers would.  The blower wheel inside their housings then maneuver the debris in a novel, multi-patented way to use centrifugal force to separate the dusts and other particles from the air.  The ACBs then eject the debris and blow it through a shoot and back into the place where it came from, usually outdoors, but they could also direct the particles back into the column of air or the conveyor loading a silo.  The clean air then blows out where you want it.  The Air-Cleaning BlowersTM accomplishes all this without any type of filter elements or media that need replacement, labor or other maintenance cost.


Other filters and air purifiers that use filter elements, even self-cleaning devices, 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 helping to properly ventilate greenhouses.  They can also blow clean air into an evaporative (swamp) cooler to keep its media clean longer.  Unlike cyclonic systems, ACBs do not spin the contaminants around and have no valves to clog.


Another key feature that can be especially helpful to farmers is that the ACBs can remove rain, mist and snow from the air.  Keeping out outside water not only helps the air stay dryer and reduce the load on any air conditioning, refrigeration, heating or dehumidifying equipment, it also makes it easier to control accurately the climate inside the greenhouse.  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.


Our ACBs were tested independently at an internationally-recognized filter-testing laboratory to prove 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 almost half of the particles down to 0.3 microns in the air.  The smallest particles most people can see are about 50 microns.

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 greenhouse you operate.  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.


  • Pressurizing greenhouses, hothouses, and storage areas to keep out dust

  • Keeping motors and other electrical equipment ventilated and clean

  • Properly ventilate greenhouses

  • Providing clean feed air to engines and air compressors

  • Ventilating and keeping pollen, dust, and other contaminants out of the greenhouses and other buildings

  • Providing clean air for heat-exchangers, cooling towers, air-cooled condensers and evaporative (swamp) coolers to minimize clogging and maintenance
