Advantaflo™ Inlet Technology

Excessive air velocity at the inlet of a baghouse can cause many problems. Heavy buildup in the inlet area can cause blinding of the bags. Pressure drop increases can cause higher operating expense. Abrasive particulates can cause premature wear to the filter media and baghouse components. Ultimately, the excessive turbulence caused by such a condition will cause dust to be reentrained in the gas stream, to be filtered over and over again.

Menardi offers exclusive capability for retrofitting your baghouse to eliminate nearly all the problems associated with excessive inlet velocity, by installing patented inlet configurations appropriate to your application.

The Cascadair™ inlet diffuser evenly distributes the incoming gas flow by uniformly diverting a portion of the gas at each of a number of successive plates. Each plate has a large abrasion-resistant impact area in the path of the gas stream, yet offers minimal horizontal surface, preventing material buildup. This design minimizes reentrainment of previously collected dust, distributes gas flow evenly, minimizes abrasion of filter bags, reduces collector pressure drop, and can be used with all types of collectors.

The Expandiffuse™ inlet was developed to reduce gas flow velocity into the dust collector by over 90% by using two specially desined diffusion grids mounted at right angles to each other.

Both of these designs have been installed and proven under field conditions at numerous customer locations worldwide.

Depending of the application, these units can result in up to 40% better filter rate performance, significant reductions in pressure drop and energy consumption, prolonged filter lifetime as well as elimination of abrasion in the hopper and on the bags, and elimination of dust reentrainment in the gas stream. Under field conditions, dust inlet velocity has been reduced in actual measurements from 3500-4000 fpm to under 200 fpm.

Both the Cascadair and the Expandiffuse can be retrofitted to improve the performance of any style or make of non-cylindrical pulse-jet or cartridge collector. The Cascadair can also be used to improve the performance of any dust collector with a hopper inlet, including cylindrical pulse-jet, shaker, or reverse air type units.
