The company has dedicated inside free and outside free trade zones to re-export to CIS and African countries. In 1995, AAF established its unit in Riyadh, Saudi Arabia. It was the first MNC air filter company of the region. The unit is ISO 9001 certified and Recent investments in manufacturing and supply chain have resulted in further improved quality assurance and smooth logistics. AAF has occupied an advantageous position in the region and has maintained the leading position in the fitration industry. By 2006, the company entered Indian market by setting up its first manufacturing unit in Bengaluru, India. Itis India’s, first and the only fitration company who installed auto scan test facility to test HEPA and ULPA filters as per EN 1822 international standards. The unit also has a cleanroom of ISO Class 100000.

Superior industry knowledge and an outstanding team of air fitration professionals mean the customers receive top quality products and services at a competitive price. From inexpensive disposable panel fiters to high efficiency extended surface fitters with antimicrobial media, AAF markets the widest range of air fiters available. AAF has developed and introduced most of the fiter designs throughout the industry, including the mini-pleats, extended surface bag fitters and PerfectPleat.Kitchen exhaust systems provide a means to remove heat and contaminants (smoke, grease aerosols, and water vapor) generated during cooking operations. While exhausting these items provides a better indoor environment, it can cause problems outdoors to neighboring facilties due to the associated odors and particulates emitted. ‘The amount and type of contaminants generated from a kitchen exhaust application will depend on the cooking operations taking place inside. The contaminants include gases, vapors, aerosols, and particulates. Therefore, kitchen exhaust fitation must incorporate a wide range of fration types and be versatile to provide an adequate solution. Commercial kitchens typically include grease and moisture capture devices at the cooking locations. These may be in the form of hoods with baffles or other equipment to remove the initial amount of grease aerosols and particulate. The exhaust air stream will have carry over of contaminants that are not removed by these devices, or from cooking operations that do not use removal devices at the cooking location.Relative Size of Comm Particulate Filtration (ierons, 10° | ry | = = Oil & Cooking Smoke Figure Grease and Smoke (Particulates) Cooking operations produce grease and smoke covering a wide range of particle sizes (see figure above). The best firation solutions employ several stages, typically starting with washable fitters folowed by muitiple stages of increasing efficiency. In many cases, washable electrostatic precipitators are used to provide high overall efficiency and allow washing. Whatever filtration arrangement is used, proper maintenance schedules are key to ensure safety by removing build up of grease from the system. The NFPA Standard 96 dictates the following inspection and as needed cleaning schedule for exhaust systems.

Particulate filters are not effective against these gases, partly because of their small diameter (see figure above). Odor removal requires the use of gasphase fitration media such as activated carbon, which utiizes pore structure and surface area to adsorb the odors. Because surface area and pore structure are critical, filtration solutions must remove all grease and mists before the exhaust air contacts the gas-phase media. Otherwise, the media will be rendered useless and can become a fire hazard. Keeping proper maintenance schedules for exhausts ducts and fitration systems promotes their long term performance and safety.Housing AAF Kitchen Ecology Unit - Pollution Control unit comprises of robust design to encounter the most intense kitchen exhaust treatment.

In applications with ighter loading of particulates, solutions may solely use stages of particulate fiers. In both cases, it is critical to performance and safety that proper maintenance, cleaning, and replacement are performed as required for the application. Odors (Gases) Odors result from the release of volatile organic compounds during cooking operations. These volatile organic compounds are in the gas -phase; they are not removed by the particulate contaminant solutions mentioned above. ‘The most widespread solution to remove these compounds is activated carbon applied in filtration cells such as metal cassettes or canisters. In some instances, applications have used a blend of activated carbon and other media. The fitration cells are commonly designed to achieve at least 0.1 seconds of residence time, however, the actual configuration and associated residence time will depend on the cooking operations taking place inside the kitchen. Exhaust of plume at the same level: ‘The kitchen exhaust hood design provides optimum performance and energy efficiency in commercial kitchen ventilation systems by properly selecting and sizing exhaust hoods. Plume raised will be captured by the hood and removed by the suction of the exhaust fan at the same levelGrease / Particulate Filtration Pre- Filters (MetaNet) Permanent Metal Filters - MetaNet are ideal for high-moisture situations.

Engineered to handle a variety of dust types and applications, the one of a kind RotoClone ® W is ideal for most food and beverage industry processes, including those that produce wet and sticky residue with proven installations. 1. Fire Barrier ‘The RotoClone® W is Factory Mutual (FM) approved to prevent fires originating in the Kitchen or exhaust ductwork passing beyond its outlet, therefore preventing costly damage and shutdowns. The water curtain in the unit serves as a fire bartier and prevents the spread of fre to the exhaust duct, even in the event of a fire in the duct from the kitchen exhaust canopy to the unit. Water consumption is minimal 2. Grease Vapor Collector The RotoCione® W offers high efficiency in coalescing and capturing grease vapors. The vapors condense in the unit where they congeal on the water surface of the irigated impeller blades prior to being sluiced to drain. Contamination of downstream ductwork is virtually eliminated. 3. Exhaust Fan The RotoClone® W is also the prime air mover for the k itchen range exhaust, replacing the conventional fan. Unlike a conventional fan, routine cleaning of the impeller is unnecessary. The RotoClone® W is quiet and can run 24 hours a day for extended periods without maintenance. 4. Odor Control Independent tests have shown collection efficiencies approaching and exceeding 99% for most odor causing contaminants. The result is a significant reduction in the odor concentration carried in the kitchen exhaust. Complete elimination of odor is notoriously difficult to achieve without expensive additional treatment, nevertheless the RotoClone® W alone reduces odor and removes virtually all the fats, greases and oils that cause much of the odor problem.
