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.

Design features of G-3 Drum Filter Δ Designed to help meet requirements from NFPA, ATEX, CE, FM, OSHA, etc.

Δ “Clean Floor” design and smooth enclosure interior to prevent dust accumulation.

Δ No electrical components or connections within the airstream

Δ All potential spark generating issues resolved

Δ Hydrex media: 85% to 10 micron efficiency

Δ Large Radius Elbow Duct Connection points for improved Airflow

G-3 Stage 1

Rotary Drum Filter

Multiple Configurations

Model number indicates drum diameter + number of cage sections

7-4 drum filter indicates 7 foot drum diameter and 4 cage sections

Hydrex Media 85% > 10 Micron

Additional Stages of Filtration (Optional)

Δ Stage 2: Pocket Filter, up to 80% efficiency > 5 Micron

Δ Stage 3: Pleated Bag Filter, up to 95% efficiency > 1 Micron

Δ Stage 4: HEPA Filter, up to 99.99% efficiency > .3 Micron

Stage 2 – Pocket Filter Stage 3 – Pleated Bag Filter Stage 4 – HEPA Filter

Δ Stage 2& 3 uses a custom designed, globally configured frame that fits a variety of systems
