Quality Control You Can Document
Every Zefon 25mm cassette undergoes a 100% inspection for correct filter and pad placement and to confirm that no parchment paper remains inside the unit.
Each production lot is further validated by an independent laboratory through blank sample testing to ensure low background fiber counts in accordance with NIOSH requirements.
Daily random-lot testing provides an additional safeguard for laboratories, consultants, and remediation contractors. Documentation is available upon request.
