Data Centers

  • As data centers become more prevalent in industry and government, users are seeking ways to reduce their energy costs, particularly HVAC expenses, which can account for up to 40% of their total energy expenditure.
  • Traditional cooling methods, such as air conditioning and chillers, can be expensive to install and maintain. To address these challenges, users are exploring innovative solutions to cool data centers inexpensively and decrease their reliance on conventional, more expensive cooling systems.
  • Air-Cleaning BlowersTM (ACBs) can provide a big part of that cost and maintenance reduction—both initial capital cost and long-term operating cost.


  • Reducing energy costs for cooling data centers and computer rooms

  • Pressurizing data centers and computer rooms to keep out dust, even during sandstorms

  • Providing “free cooling”

  • Ventilating data centers to reduce use of air conditioning

  • Controlling dust at loading points for trucks, rail cars and ships


  • With advancements in electronics design, modern computers and peripherals can withstand higher temperatures than their predecessors. This allows outside ambient-temperature air to provide adequate cooling if the ventilation system delivers sufficient airflow and ensures air cleanliness. ACBs excel at supplying clean air without the complexities of filter media.
  • In cases where outside air isn’t cool enough year-round or during specific seasons, data centers are turning to “free cooling” methods like direct evaporative cooling (DEC) and air-cooled chillers. Again, ACBs can play a vital role by providing the clean air required by evaporative coolers, prolonging media effectiveness and reducing maintenance. Additionally, ACBs can supply clean air to dry heat exchangers, improving energy efficiency and reducing clogging. They also enhance water-cooling tower maintenance by supplying clean air, resulting in substantial maintenance reductions.

  • 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, usually outdoors in the case of data centers. 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 to keep the media clean.
  • A notable feature of ACBs is their ability to remove rain, mist, and snow from the air, crucial for maintaining data center integrity and humidity control. Without filter media to trap water, ACBs prevent issues like impeded airflow or blockages caused by wet elements or freezing. This avoids problems such as water shedding into the building and the growth of mold and contaminants. By extracting water from the air and expelling it outside, ACBs also alleviate the workload on dehumidification systems.


  • An internationally recognized filter-testing laboratory conducted independent tests on ACBs to establish their effectiveness. Results revealed that they remove over 98% of airborne dust and particles, including virtually all particles larger than 10 microns and about 40% of those down to 3 microns. This level of effectiveness surpasses that of most air-conditioning systems.
  • Originally developed for harsh environments like steel, mining, and fertilizer plants, the Air Cleaning Blower™ (ACB) is versatile and suitable for data centers regardless of location. Their effectiveness is exemplified by their use by the US Military in the Middle East to maintain cooling in air conditioners, even during sandstorms.
