CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
For HEPA H13–H14 grades, the filtration efficiency is 99.5–99.97% as per ISO 16890. Lower grades like F7–F9 are used for fine dust and have lower efficiency. Always verify the specific grade and efficiency with the manufacturer.
Consider the required air flow rate (nominal flow 500–5000 m³/h), the type and concentration of particulates, operating temperature (60–120°C), pressure (1.0–1.6 MPa), and environmental conditions like humidity and outdoor exposure. Check the filter media grade and dimensions to fit your system.
Monitor the pressure drop across the filter; an increase indicates clogging. Clean or replace the filter media as needed, using methods like reverse-pulse jet cleaning or mechanical shaking. Follow the manufacturer's schedule and check seals and housing for integrity.
Signs include a significant rise in pressure drop, reduced airflow, visible dust bypass or emissions, and unusual noise from the cleaning mechanism. If these occur, inspect the media for damage or saturation and replace if necessary.
