Advanced Air Technologies, Inc. (AAT) products

AAT’s variable throat Venturi Orion Series Particulate Scrubber systems will remove dust and particulates from the air from almost any exhaust source. Our systems range from small point of source units to 50,000 CFM. Our unique design in particulate air scrubbers uses energy efficient geometry, incorporating dual cascading distributors and an adjustable impingement plate. AAT’s wet particulate air scrubbers are ideally suited for hydroscopic, corrosive, explosive or biodegradable dusts. Custom engineered particulate air scrubbers can also incorporate dry particulate filters.

The Apollo Series is an efficient and compact packed tower venturi scrubber system for the capture and destruction of acid gases or other compounds. The ejector / venturi design creates suction at the inlet eliminating the need for a blower. The unit"s small footprint makes it ideal for point of source applications or where space is limited. The Apollo Series venturi scrubbers can be operated in a batch process or completely automated with a full array of control options to meet your specific needs.Applications include chemical storage tanks, refilling operations, reactor vents, chemical vapor deposition systems, cylinder gas vents, industrial processing and many more.

Advanced Air Technologies, Inc. provides acid gas scrubbers to a wide variety of industries. We offer a complete air scrubber system package, including instrumentation and controls, caustic storage tank and metering pump, and skid-mounting of equipment for ease of installation.

A large Midwestern university research facility uses various Nitric Acid formulations for etching Niobium metal.  The etching process produces an extremely smooth micro-surface for maximizing the metal’s superconducting character.  The by-product of the etching process is various Nitrogen Oxides (NOx), primarily Nitrogen Dioxide (NO2).  These compounds gas out of the etching solution and become entrained and exhausted with air used to ventilate the surface of the etching tank.  Of the entire family, NO2 has the worst environmental impact, causing acid rain and having an unsightly orange-brown color.  U.S. EPA regulates total NOx emissions to < 20 tons/year in non-attainment zones and indirectly regulates NO2 by limiting stack opacity to <20%.

Ammonia air scrubbers incorporate a variety of gas-liquid contacting techniques, including packed beds, spray chambers and water jets. In every application, AAT considers all factors in selecting the optimum design. We offer complete packages, including instrumentation and controls, skid-mounting of equipment, acid storage tanks and metering pumps, and installation.

Fume air scrubbers are light duty wet scrubbers used for air pollution control. The term “fume scrubber” was made popular by the metal finishing industry, since the pollutants emanating from the open-top dip tanks were generally referred to as “fumes.” Fumes may consist of solid or liquid aerosols and/or vapors. Most of the dip tanks used in various metal finishing processes – such as anodizing, brightening, cleaning and plating – produce airborne vapors and liquid aerosols (mists).

AAT specializes in the design of emission controls that meet these requirements. Often we can combine the necessary emergency requirements with modifications to the process scrubber, thereby saving the purchase of additional equipment. Our emergency scrubbers can respond to the fume release automatically, removing large quantities of toxic or hazardous vapors and exhaust fumes during an accidental spill, tank rupture, or other emergency. After thorough analysis, we offer several fume scrubbers or exhaust scrubber solutions based on your inventory, local regulations, plant locations and various other factors. Our experience in designing emergency scrubbers for many different chemicals will provide you with the assurance that an accident is safely handled with minimal impact on the environment.

Exhaust scrubbers are air pollution control devices used in a wide variety of industrial applications. Reactor, sterilizer, and storage tank venting are common examples of processes requiring exhaust scrubbers. We offer complete exhaust scrubber packages, including instrumentation and controls, skid-mounting of equipment, installation and start-up. AAT, Inc. designs with many different scrubber types, including packed columns, tray columns, spray towers, and ejector-venturis.

In every application, AAT, Inc. considers all factors in selecting the optimum design for your hydrochloric acid scrubber. We offer complete packages, including instrumentation and controls, skid-mounting of equipment, caustic storage tank and metering pump, and installation. Hydrogen chloride scrubbers incorporate a variety of gas-liquid contacting techniques, including packed beds, spray chambers and water jets. Depending on concentration, special mist elimination techniques are required to prevent acid “fog” from exiting the air scrubber.
