Jet III Pulse Jet Dust Collectors
Environmental Systems and Services - Air Pollution Control
Siemens Wheelabrator Jet III
Our solutions become standards
By working closely with our customers to help solve their problems, we have pioneered many pulse jet filtration innovations that have achieved a number of significant breakthroughs and industrial application milestones.
Over the years, our Pulse Jet Dust collectors have made important contribu-tions to controlling emissions for the iron and steel, non-ferrous, coal-fired utility, hazardous waste and trash-to-energy industries.
Siemens Pulse Jet technology offers a variety of designs, both custom and pre-engineered, to meet specific needs. Each system is designed for cost effec-tive, reliable performance. They have been developed to clean emissions from industrial processes ranging from 500 to 1,000,000 ACFM.
Applications
Foundry Processes
Steelmaking and Non-Ferrous Processes

Ongoing JET III research and development
Siemens technical innovation and extensive knowledge are the result of our continuing commitment to product research and development, building on Wheelabrator brand technology.
One Source for Clean Air Technology
Because Siemens is a single-source supplier for all aspects of fabric filter systems, we can offer our customers the right technology for their application. This broad range of capabilities includes process analysis, system design, erection, start-up, and complete aftermarket services with comprehensive technical support, service, operator training and replacement parts for our equipment.

Tube sheet and bag attachment
Die-formed cups for added strength
Positive seal against dust leakage
Fast bag attachment without tools
Simple, one-step bagging
Improves clean-side work area
Our Pulse Jet Dust Collector uses a drawn-cup tube sheet. The tube sheet is seal-welded into the housing to create a positive seal.
The tube sheet features patented “snap-ring” bag sealing and offers a fast, one-man, one-step process for bag installation. Our tube sheet, acting as a natural bagging fixture, allows cage insertion or removal directly from the tube sheet and bags.
Venturi and cage
Designed and tested to reduce com-pressed air consumption
Venturi self-aligns for easy installation and efficient pulse cleaning
Simple interlock for rapid assembly
Quality bag support cages
The high-gain throat of the dust collector venturi is capable of cleaning more surface area of filter media with less compressed air. This provides effective cleaning of 6-inch diameter bags up to16-feet long with the collector on stream.
The venturi snap locks on the bag support cage, which is then simply inserted into an installed bag in the tubesheet.

Pulse Jet Dust Collectors
Jet III Pulse cleaning system
Our pulse cleaning hardware is designed to clean with minimum air consumption for maximum energy savings. More filter cloth area is cleaned with each pulse. Field tested on tough industrial applica-tions, the cleaning system contributes to prolonging filter bag life.
Header
The compressed air header is designed for space saving, positive alignment and convenient mounting of air valves. Header assemblies are sectionalized to permit local isolation for maintenance without shutting down the entire system. The system requires a low line pressure for energy conservation.
Double diaphragm air valve
Siemens double diaphragm air valves provide the power for cleaning up to 18 bags per row. Fewer valves per square foot of cloth mean less maintenance and fewer parts.
Manifold
Extensive research and development by Siemens Wheelabrator has resulted in a unique, energy efficient blow pipe for pulse cleaning. The 1-1/2 inch diameter manifold pipes are drilled with offset and variable size holes to ensure maximum even flow through all venturis. The fit of the manifold with the plenum is positive to maintain alignment. For bag inspection and/or removal, the manifold can be removed with minimum effort and without special tools.

High collection efficiency, low energy consumption
Our cleaning system has reserve power that can be utilized during upset condi-tions, such as higher dust loads. This reserve power also reduces the cleaning demand during normal operation.
The proprietary cleaning system has been employed and proven on a multitude of industrial applications.
Gas and particulate distribution
The JET III utilizes an engineered sinto diffusion-type baffle that reduces particulate load to the filter bags by deflection, impaction and downward flow into the hopper. Unlike other designs, the diffusion baffle is not affected by centrifugal forces developed in inlet elbows and turbulence with angular entries. The JET III sinto baffle has the advantage of operating the unit at higher filter rates with heavier dust loading, thus minimizing capital costs, space and components.
Benefits
Variable diameter holes in manifold pipe equalizes the cleaning effectiveness for each bag in a row.
Offset holes ensure air jet is loaded in center throat section of venturis.
Maximizes compressed air utilization.
Improved cleaning of all bags, lowering pressure drop and improving bag life with less air consumption.
