Filter-Free Air Cleaners
“I have another business that makes air conditioning systems for difficult environments, such as steel plants and military installations and such, but they require filters,” says Ed Roston, Air Cleaning Blowers. “I developed and patented this technology. It eliminates the need for filters, slows the spread of pathogens and protects the health of people and animals.”
Roston’s blowers work like any fan, pulling dirty air in, but the unique design of the impeller and the housing creates airflow pressure that spins particles off to the side. Depending on the situation, particles, such as dust from grain systems, can be fed back into the material. In other cases, such as livestock facilities or equipment cabs, the particles are ejected outside the enclosure.
Filtration systems catch and hold the particles. Eventually this decreases the effectiveness of the fan, increases power consumption and requires replacement or cleaning. ACB eliminates all of that.
Independent testing found the ACBs remove 98 percent of the mass of dust and dust particles in the air. This removes virtually all particles large than 10 microns, such as pollen and spores from plants, and about 40 percent of particles down to 3 microns, such as grain dust (5 microns and larger) and molds (3 to 12 microns).
“Our ACBs also remove rain, mist and snow,” says Roston. “This eliminates wet or frozen filters blocking airflow, shedding water in the building and encouraging mold growth. It also reduces the load on dehumidification systems.”
“The slight positive pressure created with our blowers helps keep dust out of the cab or modular building being ventilated,” says Roston. “Pressurization helps reduce dust around electrical components, which can be a big issue.”
ACBs can be designed to move from 50 to 3,500 cubic feet per minute of airflow needed for anything from a computer to a large factory. Roston says the model recommended depends on the size of the enclosure, changes per hour and whether the customer simply needs fresh clean air or wishes to pressurize the area. If the latter, leakage must also be considered. He notes that other factors in designing a system include whether dissipating heat, or actively ventilating to cool the area.
Roston estimates his filterless, clean air system costs about 30 percent more than a standard fan without filtration. He is actively looking for distributors and dealers. At this point, all sales are direct from the company with customized solutions.
“FARM SHOW subscribers with a clean air need should give me a call to discuss the situation,” says Roston. “Once we figure out what is needed, we can price it.”
