Cleanroom air purification in pharmaceutical, electronics, and biotechnology facilities.
Manufacturing zones requiring ISO-certified filtration with precise airflow control.
Facilities needing modular installation (flange compatibility) and easy maintenance.
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.
Featuring a brushless DC motor with G2.5 dynamic balance and vibration levels, it eliminates interference with sensitive equipment (e.g., electron microscopes or lithography tools) while operating at <50dB.
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
