Compact Dust Collector
This cyclone dust collector solves the problem of limited floor space or limited overhead clearance. Unlike conventional cyclones, the GPC dust collector uses an innovative ground-plate design that increases efficiency in a more compact unit. As a result, it costs less than comparable units and is just as efficient as dust collectors 1½ to 2 times its size. The design of the GPC dust collector provides a high-efficiency, compact unit that is available in horizontal or vertical configurations. It is designed to reduce particulate emissions at processing plants, reclaim useful material from air/gas waste streams, or as a pre-filter in front of baghouse filters. It handles a wide variety of dry materials including sawdust, sand, plastics, cereal/grain, and many others. Aerodyne, Chagrin Falls, OH 800-358-7546 www.dustcollectorhq.com

Compact Bin Vents
Flow Compact bin vents are capable of handling up to 1800 CFM. Typical applications include separating clean air from the dust-laden air of a conveying system. The compact design allows for installation in tight areas, and the air pulse-cleaning system combined with a minimum of three filter cartridges increases the cartridge effectiveness and lifespan. Features of the newly designed “square” units include: compact design; spun bond cartridges; easy cartridge removal system. The vents are 100% efficient to 1.0 micron.

As part of Ruwac’s High Efficiency Cyclone (HEC) pre-separator series, the HEC-DB features a universal direct bagging system that allows for a safe, dust-free cleanup. By emitting zero dust during the collection process, this protects users from coming into contact with its contents and safeguards them from harmful materials. Unlike other bagging systems, the HEC-DB is universally compatible, eliminating the need to purchase expensive, specialized bags. It also includes an external gravity drop system that holds the separator’s contents as you empty and change bags, allowing you to discharge the contents at the pull of a lever. Combined with the HEC’s specially engineered ability to separate dust and debris, this increases your vacuum’s collection capacity and filter life, reducing costs and maintenance time.

Downdraft Dust Collector
The Modu-Kleen downdraft dust collector contains fugitive dust. The air enters at the top of the dust collector housing and flows downward to the cartridge filters, improving the filtering process and the material-to-air ratio. Air velocities are lower than those with a conventional dust collector, reducing the load on each filter cartridge and extending filter life. Cartridge filters are positioned horizontally, requiring less floor space and making filter removal easier. A large, quick-opening door allows maintenance personnel to closely inspect each cartridge when required, without entering the filter housing. In addition, any single cartridge can be removed without disturbing adjacent cartridges. Also, each cartridge filter has a unique built-in quarter turn bayonet mount, so no tools of any kind are required for cartridge removal.

The intelligent pulse cleaning control technology minimizes compressed air use during filter cleaning reducing energy consumption. No tuning is required. Compressed air energy savings up to 90% over continuous pulse cleaning methods and up to 40% over pulse on demand methods are reported. Compact DIN rail packaging makes for easy mounting and field service. FilterSense, 978-927-4304 Beverly, MA www.filtersense.com

Modular Cartridge Bin Vent
The modular cartridge bin vent provides excellent air filtration of fine airborne particles from within a storage tank and releases clean air to the atmosphere. While material is pneumatically conveyed into a storage tank, fine particles and air are efficiently separated by the unit’s large cartridge filter. This enables clean air to pass from the tank out to the atmosphere. Reverse-jet cleaning from a compressed air accumulator pulses the cartridge filter, dislodging any fines and returning them to the storage tank. Standard materials of construction include carbon steel enamel coating or stainless steel material contact areas. Mounting on a standard 20-in.-diam tank deck, the small modular unit is easy to install. K-Tron Process Group/K-Tron Premier, Salina, KS 785-825-1611 www.ktron.com

Compact Dust Collectors
Designed to filter chemical, pharmaceutical, or other nuisance dusts, Vibraclean compact dust collectors are ideal for medium-duty intermittent operations. Typically installed outdoors, they are ideal for cold climates, since they utilize an eccentric-driven motorized shaker to rejuvenate the filters, instead of compressed air, which is difficult to maintain when outdoor temperatures are below freezing. Dirty air enters the baffled inlet, which is located in the hopper section. The top mounted, high-efficiency, direct-drive, backward inclined fan provides plenty of suction. The sound attenuator reduces the sound level to 72 dB at 5 ft for the 5-HP, 2000-CFM model, the DKPD24405. All Vibraclean models come complete with a factory-wired motor controller and a 55-gal dust storage drum. Sternvent, Union, NJ 800-383-3878 www.sternvent.com

Dust Suppression Nozzles
A new nozzle design for atomized misting equipment is engineered specifically for applications requiring smaller droplet sizes or reduced water volumes to minimize surface wetting.

De-Dusting System
Pelletron has developed a new patent-pending DeDuster. De-dusting systems are used in the bulk handling industry for cleaning granular products. DeDuster systems reduce the scrap rate and increase profitability by removing unwanted contaminants prior to processing, extrusion, and packaging. Traditional DeDuster designs require the product inlet and outlet to be in a straight line. While this design remains effective, the constant need to respond to changing processing conditions led to the design of the OS DeDuster series, which offers an offset inlet and outlet connection, for installation in existing angled silo outlet pipes, without changing the pipe geometry. All other features of the company’s technology, such as the magnetic field and the Venturi zone, remain unchanged. Pelletron Corp., Lancaster, PA 717-293-4008 www.pelletroncorp.com

Dust Absorption System
When Powder Activated Carbon (PAC) is transported mechanically, dust is a major issue. The Sodimix is a PAC dust absorption system that eliminates any dust created by screw conveyors feeding into slurry tanks without the use of air filters. The Sodimix principle is to pre-mix the PAC into a wetting/agitation immersion pipe with a high-velocity shear mixer, while a water eductor creates negative pressure in the same outlet, vacuuming any suspended dust through a unique reverse air/water filter. During the automatic cleaning cycle, a three-way valve diverts the supply water through the air/filter to collect and rinse the PAC particles captured from the conveying process. This new system is completely dust free and can be easily mounted on existing dry to slurry processes. Typical applications include PAC, polymers, potassium permanganate, and clay.
