ghouse Filters
Although there are only three basic types of baghouses - shaker, pulse, and reverse air – there are hundreds of different styles of bags. Filters require regular cleaning and periodic replacement to maintain peak performance and baghouses depend on an exact fit of the replacement filters to function properly. AFF manufactures all styles of replacement baghouse filters from a selection of fabrics suited to address specific applications. Scrim-supported felts offer added strength and durability so filters can withstand abrasive dust and frequent cleaning to extend the life of the bag, while providing fine particle separation and excellent dust release properties.

leated Filter Elements
PulsePleat filter elements increase filtration efficiency, helping reduce emissions, increasing airflow for more throughput and production, and leading to potential energy savings by requiring less compressed air for pulse cleaning. This media – a product of 100% spunbound polyester media – is unlike traditional felt fabrics because of its tight pore structure, which resists surface penetration of particulate and has rigid physical properties that allow it to hold a pleat without needing supporting backing material. Once pleated and molded into a filter element, the surface area is two to three times greater than conventional filter bags. That extra filtration area reduces operating differential pressure and air-to-cloth ratios. GE Energy, Kansas City, MO  800-821-2222  www.ge-energy.com/filtration

V100286.tifacuum Material Receivers
Features of these vacuum material receivers include: versatile feed inlets, dust collection ports, inspection ports; welded vessel; bolted or no-tools access filter cleaning; controllers mounted or remote with load cells S-style or compression options; receivers are available with microprocessor controller or a programmable logic controller.

e-Dusting System
De-dusting systems are used for cleaning of granular products. The product flows into an adjustable inlet funnel at the DeDuster. The adjustable inlet funnel distributes the product evenly to the central conical wash deck, also called CentraCone, and provides a smooth flow. A high-efficiency fan generates wash air that pushes the air through holes and slots in the wash deck for efficient contaminant removal. Next, the material flows through the circular Venturi zone surrounding the wash deck. Contaminants will be carried to the circular dust air channel. The new DeDuster is adjustable for cleaning rates from 10 to 600 lb/hr. Pelletron Corp., Lancaster, PA 717-293-4008  www.pelletroncorp.com

odular Cartridge Bin Vent
This modular cartridge bin vent provides high 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.

Cu294f_100298.jpglosed-Cycle  Dust Recovery System
The E3 bag spout interface protects operators and facilities from exposure to airborne material dusts that can often escape during bulk bag spouting. The closed-cycle dust recovery system secures and encloses the bag spout within a sealed containment cylinder. The sealed cylinder then lowers to elongate the spout and form the bag into a conical shape, aiding in complete material discharge from the bulk bag. The sealed cylinder also works to protect the material, and the total process operation, from the introduction of migrant contaminants. A 350-cfm air flow capacity dust collection system, with MERV 11 filtration efficiency, recovers and filters the material dust for re-introduction to the process.

u2966_100300.jpgBin Vent/Dust Collector
The Modu-Kleen Series 250 bin vent/dust collector is designed to vent bins, storage silos, mixers, blenders, pneumatic conveying systems of any type, or any other device or process that must contain or control dust particles. It can meet the most stringent air pollution codes. It is controlled by solid-state electronics and is self-cleaning for minimum maintenance. Built as an integral part of the bag cage, the cone jet diffuser directs a shock wave of air down the entire length of the bag during the cleaning cycle. This shock wave improves the unit’s efficiency when compared to other Venturi-type dust collectors that direct the shock wave over only a portion of the bag. The filter bags are cleaned one row at a time, so the unit can operate continuously. There is no need to shut down for cleaning. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com
