This small Torit® PowerCore® dust collector was tested at a large fiberglass factory because the old baghouse (shown behind the Torit PowerCore) often plugged with the glass wool fibers.
Industry: Insulation Manufacturing
Problem: Stringy, fibrous material tends to nest and plug airflow within collector
Solution: Torit PowerCore CP Series, which resists clogging
The fibrous nature of glass wool (a.k.a. rock wool or fiberglass) makes it perfect for insulation in homes and buildings all over the world. But this same stringy fibrous quality makes it difficult to produce, handle, cut, and shred. At this major European manufacturer of glass wool insulation blankets, the material nests on itself inside the dust collectors, often causing a bridge between filter bags that plugs airflow.
When an existing tubular baghouse needed replacement, the production manager called Donaldson Torit, searching for a better solution.
The production manager agreed to test one of the new smaller, smarter Torit PowerCore dust collectors on part of a production line, to see if it could meet the challenges of the fluffy, agglomerative glass wool trim pieces.
400-Hour Production Test Results:
Bridging occurs in baghouses because the pulse-cleaning knocks accumulated dust down the length of the filter, and often it accumulates in the upper and lower interstitial spaces. On material like glass wool that tends to stick to itself, the accumulation builds and eventually forms a bridge that blocks airflow. Torit PowerCore is engineered with computer-modeled fluid flow analysis to manage the incoming dirty air and the velocities directed into the filter pack, avoiding interstitial problems.
Another reason bridging and plugging are prevented in the Torit PowerCore collector is the Compact Oblique Pulse Cleaning System. It is a proprietary, computer-modeled pulse-cleaning technology designed to match the obround shape of the PowerCore filter pack. The pulse pattern covers the entire media pack and thoroughly blows the dust out of the fluted channels in an energy-efficient manner.
