When working in a greenhouse or hothouse, ventilation is essential, but dust and pollen remain inescapable problems. Whether planting seeds, spraying pesticides, sowing dirt, or watering plants, airborne particles and excess air droplets are common occurrences. While some activities may generate more particles than others, the importance of controlling these particles and ensuring proper ventilation in greenhouses cannot be overstated.


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.



  • 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


Air Cleaning BlowersTM (ACBs) operate by drawing dirty air into their housings, similar to conventional fans or blowers. Inside, a patented blower wheel uses centrifugal force in a unique way to effectively separate dust and other particles from the air. The ACBs then eject the debris, directing it back into the environment, such as outdoors or into a conveyor loading a silo. Meanwhile, the cleaned air is released wherever needed. Remarkably, ACBs achieve all this without the need for filter elements or media that require replacement or maintenance, saving on labor and costs.


In contrast, other filters and air purifiers relying on filter elements, including self-cleaning devices, often suffer from rapid and costly clogging. This not only reduces fan effectiveness but also increases energy consumption and necessitates frequent maintenance and repair. ACBs, however, avoid such issues due to their lack of filter media, ensuring consistent airflow, air pressure, and steady energy consumption for various applications, including ventilation, pressurization, or feeding air compressors. Additionally, ACBs can extend the lifespan of evaporative coolers by blowing clean air, thereby keeping their media cleaner for longer periods. Unlike cyclonic systems, ACBs do not rotate contaminants and are free from valves that may clog.


  • Another significant benefit for farmers is that ACBs can effectively remove rain, mist, and snow from the air. This not only helps maintain a dryer environment and reduces the load on air conditioning, refrigeration, heating, or dehumidifying equipment but also facilitates precise climate control inside the greenhouse. Additionally, because ACBs lack filter media to trap rain or snow, there’s no risk of components becoming wet or frozen, ensuring uninterrupted airflow.
  • Our ACBs underwent rigorous testing at an internationally recognized filter-testing laboratory to validate their effectiveness. The results demonstrate that they remove over 98% of the mass of dust and other particles from the air. Specifically, the laboratory findings indicate that ACBs eliminate virtually all particles larger than 10 microns and almost half of the particles down to 0.3 microns in size. This exceptional filtration capability ensures cleaner and healthier air in the greenhouse environment.
  • Originally developed to withstand harsh conditions in steel mills, mining operations, and fertilizer plants, the Air Cleaning BlowerTM is adaptable to any type of greenhouse operation. Our ACBs are so reliable that they are currently utilized by the US Military in the Middle East to ensure continuous cooling of air conditioners, even in the midst of sandstorms.
