Clean Bench (basic) BC-21B
Clean Bench (Basic) BC-21B
Catalog Number: AAHA6033U | Vertical Laminar Flow Hood
The MBI Clean Bench (Basic) BC-21B is a vertical laminar flow clean bench that provides 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 polyester fiber pre-filter traps larger particles and extends the service life of the main filter. The unit features an exclusive diffusing muffler structure for high-quality laminar flow, a durable grade 304 stainless steel work surface and a quiet working environment of less than 65 dB.
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 satisfying Class 10 (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 increases the life of the main HEPA filter.
- Exclusive diffusing muffler structure forms high-quality laminar flow.
- Quiet and comfortable working environment (less than 65 dB).
Convenience
- Built-in differential pressure gauge for easy checking of HEPA filter condition.
- Comfortable front access to cartridge-type filters for easy replacement.
- Easy blower speed adjustment by the control panel.
- Highly durable, rust-free and easy-to-clean grade 304 stainless steel work surface.
- The inner left side magnetic board allows memos and small tools.
Safety
- UV-blocking and impact-resistant tempered glass door.
- If the sash is opened during UV-lamp operation, the UV lamp automatically turns off to protect users.
- Lighting mode selection by 3-position toggle switch (UV / off / fluorescent) preventing harmful UV exposure.
- Smoothly sliding front door stoppable at any height for user safety and easy transport of equipment into the workspace.
- Protection against over-current.
