3. Blizzard bag filters are reliable, low-maintenance dust collectors designed for cleaning air and gases of high contamination in the form of dry coarse as well as fine particulate dust as well as different types of fibrous and non-sticky dust. It can be installed both outside and inside a facility. Potential uses include: - dust collecting for ovens and casthouses; - silo loading/unloading dust collection; - dust collection for bulk handling, conveyor belts, conveyors, elevators; - dust collection in grinding mills, sawmills, sifting machines, cold storehouses, holding furnaces, and batching plants; - dust collection for thermal and mechanical metal cutting processes, welding processes, etc. The machines can be used in the food, chemical, metallurgical, metal processing, mountain ore, pharmaceutical, engineering, and other industries as well. Fig. 2 In its classical design, the Machine is equipped with a “field valve” in the lower part of the hopper (Fig. 3) as well as automated hopper dust discharge. Rotary valves can also optionally be used (Fig. 4) as well as a double dump (Fig. 5) and a worm transporter (for multiple frames) (Fig. 6). - 3 -

5. General features of the machines: Parameter title Value Aerodynamic resistance, Pa 2,000 Filtration speed, m/min 1-2 Dust concentrationa at the inlet, up to g/m³ up to 150 Dust concentration at the baghouse exit, 5 maximum, mg/m³ Maximum incoming gas temperature, 150 maximum, °С Compressed air pressure in pneumatic system, 5-7 bar Frame design material ST3 GOST 380-2005 Metalware material Zincked steel (or stainless steel by order) Filter element Round polyester bag Hopper volume, m³ 2.5 In addition to the basic standard package, the Machine can be complemented with other additional functions: - a platform can be installed for conducting baghouse maintenance; - explosion-proof Machine design: installation of explosion-proof membranes, filter elements with anti-static fibers and threads, additional grounding systems, IP 64 electricity, etc. - heat insulation for the frame and hopper (50 mm of synthetic insulation and zinc coating); - a control cabinet providing for collection of data from the dust transmitters, pressure changes, and equipment condition (fan, worm, feeder). It also allows for the feature of setting up alarms on the machine’s operating condition, accidents, technological blockages, emergency stops, and device deactivation from the fire alarm signal. - other functions, depending on the production facility's needs.

The damper plate also distributes and redirects the air flow, facilitating even distribution of the air masses along the bags. This boosts the level of air cleaning and the concentration of dust that the baghouse can handle. It also extends the filter elements’ service life and allows for filter bags to be able to be used in a baghouse with a total area of up to 126 m² with a relatively even load. As the air passes through the baghouse, it leaves dust and other impurities on the outside of the filter, thus becoming cleaned and exiting via the clean air chamber into the air duct. Since some of the “dust” sticks to the material, thereby increasing resistance to the air flow, a pneumatic regeneration system is included in the basic package. The air is fed via a nozzle located in the clean air chamber into the bags in a powerful pulse, consequently blowing the stuck dirt mass off of them. That occurs on a timed basis without necessitating the ventilation system fans to stop. The air in the pneumatic system accumulates in the receivers (one section each). They need to be attached to the external compressor or the compressed air supply main. For that purpose, there is also a fitting on the receiver as well as a condensation drain valve. The air valves that are used are either produced in the United States or imported from Germany or Italy. They're all certified for baghouse equipment pneumatic cleaning systems. If a differential manometer is installed, bags cleaning will be able to be set up not only in a timed fashion but also based on the level of bags’ “contamination”. A differential manometer can also sound off in the event that one of the bags becomes damaged. - 6 -
