On-Site Test Blows Away Skepticism of Torit® PowerCore® Cleanability

After testing the cleanability of the PowerCore® filter pack at his grain facility, the manager commented, "Our trials indicated that the filter packs are able to purge very well."

Industry: Grain

Problem: On site-evaluation of the cleanability of the new Torit® PowerCore® dust collector in high-dust operation

Solution: The PowerCore® packs were "able to purge very well."

“But will it pulse clean?” was the facility manager's first question when he was introduced to a PowerCore® filter pack from Donaldson® Torit®.

“The theory behind PowerCore is technically valid but the media looks strange compared to a baghouse filter,” he commented. “I doubted the narrow channels of the media pack could be pulsed cleaned.”

The facility manager agreed to test Torit PowerCore at his grain processing facility, in a high-dust area that sees a variety of particle sizes, from very small (submicron) to large.

Positioned over the silo loading chutes, the PowerCore® filter packs captured dust until the pressure drop increased to 4 "w.g (pressure drop expressed in inches water gauge) and triggered the cleaning mechanism. This sends a pulse of clean air back through the filter packs to blow off collected particulate. After only 3 pulses, the pressure drop fell to the low set point of 1 "w.g. This quick pressure drop recovery was seen repeatedly.

“Our trials indicated that the filter packs are able to purge very well,” the manager commented.

The main reason for the filter packs get cleaned well is that they are constructed with Donaldson's advanced fine fiber filter media, Ultra-Web® . This microscopic 'web” layer, bonded to a sturdy substrate, captures most of the particulate on the surface of the media, allowing dust to be more easily pulsed off during the cleaning cycle of the collector.

Another reason for the consistently successful pulse-cleaning is Donaldson's proprietary Compact Oblique Pulse Cleaning System (illustrated at right) on Torit® PowerCore®. Designed to match the obround shape of the filter pack, the pulse energy spans the entire media pack, cleaning all areas without wasting energy.

After testing the cleanablility to his satisfaction, this facility manager ordered two Torit PowerCore® bin vents units to capture dust from the grain conveying system in the barage loadout operation.
