"But will it pulse clean?" was the facility manager's first question when he was introduced to the PowerCore filter pack from Donaldson Torit.
"The theory behind PowerCore is technically valid but the media looks strange compared to a baghouse filter," he said.
"I doubted the narrow channels of the media pack could be pulsed clean."
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 1 KPa 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 0.25 KPa. This quick pressure drop recovery was seen repatedly.
"Our trials indicated that the filter packs are able to purge very well," the manager said.
The main reason the filter packs get cleaned well is that they are constructed with Donaldson's advanced nanofiber filter media, Ultra-Web. This microscopic "web" layer, bonded to s sturdy substrate, captures most of the particles 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 Compact Oblique Pulse Cleaning System on Torit PowerCore Units.
Designed to match the obround shape of the filter pack, the pulse energy spans the entire media pack, cleaning all areas without wasting energy.
