Manufacturing zones requiring ISO-certified H13 filtration with precise airflow control.
Facilities needing modular installation (flange compatibility) and easy maintenance.
FAQ :
1. How does the bottom-access design simplify HEPA filter maintenance in sterile environments like ORs?
The tool-free, bottom-loading mechanism allows single-person filter replacement without dismantling the unit or disrupting laminar airflow – critical for maintaining ISO Class 5 conditions during surgeries or microelectronics production.
2. What makes this FFU suitable for vibration-sensitive applications like semiconductor metrology?
Featuring a brushless DC motor with G2.5 dynamic balance and <3µm vibration levels, it eliminates interference with sensitive equipment (e.g., electron microscopes or lithography tools) while operating at <50dB.
3. Can the compact 575x575x250mm frame integrate with existing cleanroom grids?
Yes, it supports:
Drop-in installation for standard 2'x2' T-bar ceilings
Flange-less sealing to prevent particle leakage
Optional 1200x600mm adapters for ISO 14644-1 recertification
