Baghouse Conversion Service
Outdated-shaker, reverse-air, or bottom-load pulse-jet baghouses can be converted into a top-load reverse-pulse-jet baghouse with walk-in plenum or roof doors for filter bag or pleated filter maintenance. Cost savings are realized by reusing the existing collector’s hopper, support steel, exterior walkways, ladders, and dust removal equipment. After the conversion, the ventilation air volume to the process is usually increased by as much as 30%. The scope of service includes engineering, fabrication, field demolition, and field installation. A converted unit with new, larger inlet ductwork
is pictured.

Wet Particulate Dust Collector
Booth 4047 – The Hydro-Lance wet particulate dust collector with Submerged Air Venturi (SAVe) technology avoids operational issues associated with a standard venturi scrubber system, including pump failures, small-orifice nozzle clogging, material failures, and general maintenance headaches, while still providing the Venturi collection methodology. The collector saves capital cost with its simple economical design, replacement costs with its corrosion-resistant construction that extends equipment life, energy (because pumps are not required), maintenance (with no moving parts, spray nozzles, recirculation pumps, or piping), floor space, and water—the sump liquor does not need to be diluted. Key features include >99% removal guaranteed; thermo­plastic, steel, or other materials of construction; automatic sludge removal; removable Venturi throat; and an integral exhaust fan.

Sonic Jet Dust Collector
PAC Sonic Jet dust collectors feature a low-maintenance, safety-first design that places all serviceable components on the outside of the casing to permit inspections, part replacement, and other maintenance to be performed without requiring human entry into the unit. By eliminating the need for workers to enter the dust collector at the equipment design stage, the unit safeguards workers from exposure to potentially harmful situations while eliminating concern for compliance with OSHA’s 29 CFR 1910.146 (regulating permit-required confined space entry). In addition, while traditional baghouse collectors often require workers to climb inside the unit for filter inspection and replacement, this collector includes a front-loading filter cartridge array that enables filter inspection and replacement to be performed by one person from outside the unit with no tools, by simply sliding the cartridge in and out like a file drawer.

Downdraft Dust Collector
Booth 1304 – The Modu-Kleen downdraft dust collector represents the latest dust collector technology to contain 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.

Filter Elements
Booth 3617 – HSL filter elements are made of sintered polyethylene, and the surface is coated. The coating thoroughly covers all the beads at the surface of the body matrix, thus assuring total surface filtration. The filter elements are manufactured in various sizes with filter areas ranging from 5.8 to 82 sq ft. The shape of the filter elements offers a large active filter surface within compact dimensions. The filter medium is inherently rigid and therefore does not require a supporting cage. As a result, there is no friction or flexing during jet-pulse cleaning, and the useful life of the filter elements is increased.
