Filtering Drum

Definition and Structure

PTFE-coated filter cartridges are cylindrical components used for filtration, featuring a surface coated with polytetrafluoroethylene film. This film has small sieve holes that block most sub-micron dust particles and forms a permeable dust barrier on the filter material surface, effectively preventing dust from entering the interior of the material. The cartridge usually consists of pleated filter media, metal mesh, top ring, base, and seal.

Features and Advantages

1. High filtration efficiencyPTFE coated filter sleeves offer high filtration efficiency for ultra-fine dust particles, exceeding 99%, especially for particles ranging from 0.1μm to 1μm.

2. Excellent dust removal effectDue to most dust particles being blocked on the outer surface of the filter material, they can be promptly and effectively removed under the blow of compressed air, maintaining the cleanliness and efficient filtration capability of the filter element.

3. Low operating resistanceThe surface friction coefficient of the PTFE coated filter cartridge is low, and it offers excellent dust stripping properties, resulting in relatively low operating resistance and allowing for dust removal at low pressure.

4. Chemical resistantPTFE materials boast excellent chemical stability, being almost unaffected by any chemicals, thus ensuring the filter sleeves maintain stable performance in harsh chemical environments.
