Sioux SteelDust Suppression Hopper
This dust suppression hopper can be installed under a feed point where it is suspended above the target and kept at operating level. A small degree of natural agitation as the hopper is filled helps exclude air from the material being transferred. At the point of loading, or transfer, the system concentrates the discharge of dry goods as a solid column through free air into any target repository including trucks, rail cars, storage containers, bags, or stockpiles. Previously, trucks taking on a load literally disappeared in the dust cloud. Uncomplicated to install and easy to operate, the DSH system will reduce hazards and health risks, dust, and wastage.Sioux Steel, Sioux Falls, SD 800-557-4689 www.siouxsteel.com

K-TronFilter Receiver
The Filtair series filter receiver provides automatic material-from-air separation. The tangential inlet located in the receiver’s circular hopper provides a cyclonic separation of the material from the air stream. Remaining airborne material is trapped by the filter element. Timed, compressed air pulses clean the filter bags or cartridges dropping the once airborne material into the hopper. Only a single row of the filter element is pulsed at a time, leaving the remaining filter element on-line. The filter element is protected from the material mainstream by a deflector shield. Efficient performance of the filter receiver is achieved through the proper selection of filter media and the correct air-to-cloth ratio. The unit has a quick-access door where the filter element is easily accessed for service and comes with an enclosed solid state timer control panel. Materials of construction include carbon or stainless steel. K-Tron, Salina, KS 785-825-1611 www.ktron.com

The addition of the oval configuration to the Torit pleated filter bag program allows Donaldson to put its nanofiber technology into all popular makes and models of baghouse collectors. The Ultra-Web SB media used in the pleated bag program consists of a layer of nanofibers (most of which are only 0.3 microns in diam) over a sturdy spunbond polyester substrate. The substrate is known to work well in applications where agglomerative dust is problematic. Donaldson Company, Inc., Minneapolis, MN 800-365-1331 www.donaldson.com

Dynamic Air Inc.Bin 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. The bin vent/dust collector 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 it can operate continuously. There is no need to shut down for cleaning.Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com

Monitor Technologies LLCParticle Emissions Detector
The DustAlarm particle emissions detector, or broken bag detector, is designed to detect filter failures and leaking filters in the exhaust ducts of bag houses, cartridge collectors, cyclones, and other dust collection systems containing filters that may break or wear out with time. The DustAlarm broken bag detector uses time-proven triboelectric technology to continuously monitor the level of dust emission in dust collection system exhausts. When an increase in emission level exceeds the user adjusted setting, an alarm is triggered as indicated by the unit’s output relay changing state. An extended insulator guards against material build-up problems. Monitor Technologies LLC, Elburn, IL 800-766-6486 www.monitortech.com

Scientific Dust CollectorsBaghouse Dust Collector Retrofit
This retrofit system is designed to improve the cleaning systems in all existing baghouse dust collectors. This cleaning system improvement can be applied to all reverse pulse-jet baghouses for all baghouse brands. If the blowpipes can be removed, then the supersonic nozzles can replace the old cleaning systems. The benefits of this retrofit include the ability to eliminate the flow restricting venturi at the top of the filter bag, lower system operating pressure by reducing pressure drop as much as 2 in. WG, and superior bag cleaning by inducing more than three times the amount of cleaning air into the filter media than other generic baghouse designs.

Imperial Systems Inc.Cartridge Filter
The DeltaMaxx cartridge filter eliminates costly media dead zones. After a typical cleaning cycle, as much as 30% of a filter is still blinded and choked with particulate. Over time, these media dead zones reduce filter life and delta p efficiency which leads to more frequent and costly change-outs. This new filter has the patented Pulse Distribution (PD) technology that eliminates filter dead zones by distributing the cleaning pulse across the entire surface of the media. The cartridge typically improves pulse effectiveness by over 40%. The improved filter life and increase in efficiency saves time and money.
