Overview
The Fenggu Laminar Flow Hood supplies HEPA-filtered vertical unidirectional airflow over the critical work area. It is designed to establish a local ISO 5 / Grade A environment within a Grade B or C cleanroom, reducing particulate contamination risk during open product handling, inspection and other critical operations. The modular stainless-steel structure can be assembled on site and configured around the process footprint.
Key Features
- Vertical unidirectional airflow for local ISO 5 / Grade A protection
- SUS304 stainless-steel modular construction for on-site assembly
- Adjustable airflow velocity from 0.35 to 0.65 m/s
- Front PVC strip curtain helps define and protect the critical zone
- Button control or optional PLC touchscreen interface
- Optional differential-pressure and airflow-velocity display with alarms
