Vertical laminar flow clean benches!
ISO Class 4 air cleanliness as per ISO 14644-1. (equivalent to Class 10 as per US Federal Standard 209E)
Nominal downflow velocity. (0.45 m/sec for BC-H)
High-quality pre-filter and main HEPA filter.
Ergonomically sloped front.
Filtration Features
• ISO Class 4 (US Class 10) HEPA filter for optimal protection against cross-contamination.
• 0.3 μm and larger particulates removed with 99.99% efficiency, leak-tight HEPA filter, and meets class 10. (US Federal Standard 209E)
• Comfortable front access for inspection of HEPA filter and easy validation. - Standard gas detector hole for easy checking of HEPA filter leak performance test.
• High-quality polyester fiber pre-filter (with minimal pressure loss and 85% arrestance on the A.F.I. test) for trapping larger particles and increasing the life of the main HEPA filter.
- The HEPA filters life span depending on the test room conditions has a life span about 3 years.
Safety & Constructional Features
• UV-blocking and impact-resistant tempered glass door.
• If the sash is opened during UV-lamp operation, UV lamp automatically turns OFF to protect users.
• Highly durable, rust-free, and easy-to-clean grade 304 stainless steel work surface.
• Smoothly sliding front door stoppable at any height for user’s safety and easy transport of equipments into the workspace.
BC-H Features
• Interlocking Smart Door System
- Simply open the door while UV-lamp is ON. Interlocking smart door system will automatically turn OFF UV-lamp, turn ON Fluorescent lamp and Blower instead of your manual control.
• If the sash is opened more than the recommended sash height level, during operation, warning alarm will activate and alarm users to lower the window to the recommended sash level to prevent contamination of samples.
• When UV light intensity is lower than 80%, UV warning lamp is automatically ON to let users know when to change UV-lamp.
• Digital differential pressure sensor allows for easy verification of HEPA filter condition great for knowing when to change HEPA filter.
• Digital airflow rate sensor (Microprocessor) for automated airflow speed control.
- Offers continual airflow speed of same velocity and extends the HEPA filter life span.
• Exclusive diffusing muffler structure forms high quality laminar flow.
• Using a BLDC motor in the blower provides a quiet and comfortable working environment. (less than 65dB)
• Two digital displays for the best convenience.
- Even if any test is ongoing inside of the chamber, unit conditions such as velocity, temperature and humidity can be easily checked and controlled by inner display.
• The inner left side magnetic board allows some memos and small tools.
