2x4 HEPA Fan Filter Unit
Sourcing 2x4 HEPA Fan Filter Unit from Snyli Environmental Technology (Shandong) Co. Ltd. - China Import Guide
Before ordering, verify the FFU’s compatibility with your cleanroom’s classification and airflow requirements. Request the supplier’s test reports for filter efficiency (HEPA/ULPA ratings), airflow performance curves, and noise levels. Ensure the unit’s power supply and control system (AC or DC) match your facility’s electrical infrastructure to avoid costly modifications.
Confirm logistics details such as lead time, which may vary based on filter type and customisation. Standard packaging for FFUs typically includes protective crating to prevent damage during transit. Discuss Incoterms with the supplier; FOB or CFR are common for bulk shipments from China. Payment terms often include a 30% deposit with the balance due before shipment, but negotiate based on your trade history.
Quality checks should include inspecting the cabinet for material integrity and corrosion resistance, particularly if opting for stainless steel. Test the fan and control system for smooth operation across all speed settings. Request a factory acceptance test (FAT) to verify airflow rate, noise levels, and filter integrity. Ensure the supplier provides ISO 14644 compliance documentation and any required cleanroom certification for your industry.
