BC-21E (230V/60Hz)

Filtration features
Particle-free ISO 14644-1 Class 4 air
• Particle count in the work area conforms to ISO Class 4 conditions (formerly Class 10 per Federal Standard 209E). This ensures filtration of 0.3㎛ or larger particles.
• Polyester fiber pre-filter that has a small pressure loss and 85% arrestance on the A.F.L. test, serving to trap larger particles and increase the life of the main filter
• HEPA filter is airtight to the body unit by connecting with neoprene gaskets
* The HEPA filter life span is usually 3 years, but it depends on test room conditions
Construction features
Ergonomic design
- Angled front profile is free of protrusions that could interfere with visibility or obstruct taller users
- 304 stainless steel work surface - Highly durable and rust prevented work zone for easy cleaning
- Tempered glass door, durable and intercepts UV light for user safety
- The door smoothly slides up and down for maintaining cleanness and stops at any height you want
- Right and left sides also have wide glasses for a clear view
- Adjustable speed of blower with a blower controller
Lighting
- Electronically ballasted FL lamp is installed on the top center minimizing disturbance of airflow and shadows on the work zone, and relieving of technician eyes strain
Clean Bench Airflow Profile
• Room air is taken in from the top blower of the bench through a disposable pre-filter
• The pre-filtered air is purified by the secondary HEPA filter to confirm to the class
• The laminar down-flowed air flows from the dual filtering system into the working zone
• The working zone can maintain a high level of cleanness because it keeps a positive pressure to prevent outside pollution
• The purified air moves across to the working zone of the cabinet in a vertical, unidirectional stream and leaves the main work chamber across the entire open in front of the cabinet through slots.
