Clean Bench (Advanced) BC-11H

Catalog Number: AAHA5023  |  Vertical Laminar Flow Hood

The MBI Clean Bench (Advanced) BC-11H is a digitally controlled vertical laminar flow clean bench providing ISO Class 4 (US Federal Standard 209E Class 10) air cleanliness for the protection of samples and sensitive work processes. A leak-tight HEPA filter removes 0.3 um and larger particulates with 99.99% efficiency, while a digital airflow rate sensor with microprocessor-controlled blower speed maintains continual airflow at the same velocity and extends HEPA filter life. An interlocking smart door system, dual digital displays for velocity, temperature and humidity, a digital differential pressure sensor and a UV intensity warning lamp add a new level of convenience and safety, all on a durable grade 304 stainless steel work surface.

Performance

• ISO Class 4 (US Class 10) HEPA filter for optimal protection against cross-contamination.
• 0.3 um and larger particulates are removed with 99.99% efficiency by a leak-tight HEPA filter (US Federal Standard 209E).
• High-quality polyester fiber pre-filter (minimal pressure loss, 85% arrestance on the A.F.I. test) traps larger particles and extends the life of the main HEPA filter.
• Digital airflow rate sensor (microprocessor) for automated airflow speed control, offering continual airflow at the same velocity and extending HEPA filter life.
• Exclusive diffusing muffler structure forms high-quality laminar flow.
• Quiet and comfortable working environment (less than 65 dB).

Convenience

• Interlocking smart door system: simply open the door while the UV lamp is on and the system automatically turns off the UV lamp and turns on the fluorescent lamp and blower.
• Two digital displays (inner and outer) let users check velocity, temperature and humidity at any time, even during ongoing tests.
• Digital differential pressure sensor for easy verification of HEPA filter condition.
• UV warning lamp turns on automatically when UV intensity drops below 80%, indicating when to change the UV lamp.
• Comfortable front access to cartridge-type filters for easy replacement.
• Highly durable, rust-free, easy-to-clean grade 304 stainless steel work surface.
• The inner left side magnetic board holds memos and small tools.

Safety

• UV-blocking and impact-resistant tempered glass door.
• Sash alarm activates if the sash is opened above the recommended height during operation, warning users to lower the window and prevent sample contamination.
• If the sash is opened during UV lamp operation, the UV lamp automatically turns off to protect users.
• Smoothly sliding front door stoppable at any height for user safety and easy transport of equipment into the workspace.
• Protection against over-current.

Specifications

Average HEPA filter life span is approximately 3 years depending on test room conditions (optional).
