How it Works

Dust laden air is pulled into the compartment under induced draft. The air travels through our gas flow distribution baffle at the inlet of the compartment (full baffle not shown) to create a uniform flow distribution. The air is then pulled through the filter media, where dust is captured on the outer surface of the bags . Clean air passes through the filter to the clean air outlet. The bags are automatically cleaned with compressed air as the pressure drop across the tubesheet increases. After cleaning the dust falls to the hopper below were it is mechanically or pneumatically conveyed depending on the process requirements.

Cleaning System

The cleaning system consists of a compressed air delivery system. Air is pulse initiated if a high pressure drop across the baghouse is detected. The air pulse is activated through a solenoid valve. The pulse system has a pressure flow characteristic to give maximum power in a minimum time frame. This stops air flow through the element and reverses the flow in order to dislodge the collected dust, effectively cleaning the bags while the compartment remains online.

Integrated System

Modular, or Semi-Modular compartments can be combined into an integrated system with Inlet/Outlet Plenums, Dampers,  Material Conveying, Instrumentation, and Controls.

Special Features

Reduced load

Specially designed inlet baffle reduces particulate load to the filters and creates a uniform air flow distribution throughout the unit.

Optimized Cleaning

Variable hole pulse manifold pipes provide equal cleaning force to each filter bag for maximum cleaning efficiency and long bag life

Wheelabrator tool for maintenance Fabric Filter

Simple Design, Easy Maintenance
  • No special tools for bag changeout
    Stainless steal “snap-ring” is sewn into each bag forming a tight seal against the tubesheet and allowing easy, one step bagging.
  • Drawn-cup tubesheet provides strength for walking support and provides positive seal against dust leaks
