Cyclone Pre-filter Benefits – Increased Removal Efficiency | Aerodyne

Posted by Tom Hobson on Dec 19, 2019 9:15:00 AM

A significant benefit of using a cyclonic dust collector as a pre-filter for baghouses or cartridge collectors is increasing removal efficiency. A cyclone removes all types and particle sizes of dust. At larger particle size, dust collection is nearly 100% but with smaller size (ex. sub-micron) particulate the collection can typically less than 5%.

Filter Cleaning Cycle

Filters such as bags and cartridge collectors get their high removal efficiencies by building up a dust layer over the filter.  This dust layer allows air to pass through it and the filter while preventing dust particles from passing.  As the dust layers build up, it becomes harder and harder for air to pass through, hence the increase in the pressure drop of the collector.  The filter cleaning cycle is used to remove the top layers of this dust layer; thereby allowing air to pass through easier.Pre-Filter

Particles in the Dust Loading

When large particles are in the dust loading, they will block more passages of the air.  However, the layer may not be as uniform, thereby allowing high velocity channels that will allow the smaller particles to pass, with enough velocity to get through the filters.   If the dust loading particle sizes are more equal (smaller) then the dust layer is more uniform, letting less small particles through, thereby increasing the removal efficiency. 

Cyclone Pre-Filter

The installation of a cyclone pre-filter removes the largest particles, allowing only the smallest to pass.  This allows for a more uniform dust layer, thereby increasing the removal efficiency of the filters.

Inspired To Be Different.

At Aerodyne, we choose to take a different approach to collecting dust and handling materials. Our cyclones are unique in design to address common issues such as problematic dusts and space constraints. Our airlocks are chosen to fit your specific application instead of hastily installing traditional equipment options. We believe that when we see things differently, we can solve problems effectively. That's why so many people turn to us for help in solving their tough dust problems.
