The Anatomy of a Drum Filter
The Anatomy of a Drum Filter
Theory of Operation ∆ Dirty air is introduced into
the Drum Filter Enclosure
∆ The Main System Fan pulls the air across the filter media
∆ The dirty particles are vacuumed off the media by vacuum nozzles in the drum chamber
∆ Dirty particles are then returned to the process or collected in an off-line collector
1. Dirty air into enclosure
2. Main System Fan pulls across the filter media
3. Dirty media is vacuumed by nozzles
4. Dirty particles are returned to process or collected in off-line machine
Drum Filter System Styles Ibis offers the following drum filters:
Outside Drive (which can be CE certified): All drive components are
located outside the Drum Filter Enclosure.
G-3 concept: Outside Drive Drum Filter system designed specifically for OSHA,
NFPA, and ATEX compliance.
Inside Drive (which can not be CE certified). All drive components are
located inside the enclosure.
