There are two key areas we focus on when reviewing a new system layout. First, the geometry and chemistry of particulates in the air stream determine the way we configure and select components.

Clean air system flow control components such as multi-bladed dampers on the “dirty side” can no longer be used as they would gum up or fail prematurely. The second key factor is keeping particulate in suspension after it is collected and effectively conveying it to the filtration device.

Should equipment slowly fail or break down, particulate settling in the duct creates potential duct collapse, leaks in the duct, fire an,d explosion potential, and additional static pressure loss with increases in fan horsepower, fan wheel abrasion, and imbalance.

Our systems approach is divided into two categories:

Ducted Pollution Control Systems 

 These systems are often termed central systems meaning the pollution control device or dust collector is located away from the process collection point and a duct system conveys the material to the air cleaning device.

It is critical when evaluating systems that all the components included are of equal quality and value. The major components would include the dust or mist collector, capture hood (s), conveying duct, flex connector (s), fan damper, and HEPA filter assemblies. Also, duct layout, start-up and commissioning services, and controls need to be closely evaluated.

Self-Contained Dust Collectors

Self-contained dust collectors are a “complete” system by design, in that they include all the items included in a dusted system, but without the duct. These would include smaller cartridge and envelope bag collectors, portable dust collectors, downdraft benches, downdraft tables, portable equipment, and environmental control booths.

Dust Collection System Design Considerations

Dust, fume, and mist collection system design is about:

  • Maintaining airflow thru the system to minimize particulate and material deposition
  • Minimizing noise levels from components
  • Minimizing the pressure loses thru the system with proper duct and fitting configuration
  • Minimizing horsepower requirements
  • Maximizing capture with hoods with correct airflow
  • Maintaining the integrity of duct and components by selection of proper materials of construction

Vacuums and filtration research and development has led to cartridge dust collectors that solve most industrial dust and particulate challenges in a variety of facilities such as:

  • Chemical
  • Woodworking
  • Pharmaceutical
  • Food Processing
  • MetalWorking
