ECM DC brushless motor
CAV ( Constant air volume) technology
CPAS (Constant pressure apheresis system ) technology
The biological safety cabinet adopts the ECM DC brushless motor working with the CPAS and CAV technology providing safe and reliable airflow volume and pressure during the operation in BSC. Based on the ECM feature that can determine supply air volume and pressure by detecting changes in internal current and power, and realize automatic adjustment on the balance of air volume or pressure.The CPAS and CAV technologies are to precisely control airflow. When the cabinet is operated at set velocities and without read-justing the fan speed control, a 50% increase in pressure drop across the filter doesn't decrease total air delivery more than 10%.
The velocity meets USA NSF/ANSI49 standard and EN12469 standard.
Integrated filtration system
USA HV brand HEPA Filter medium are applied in the supply H14 HEPA filter and exhaust HEPA filter guaranteeing the filtration efficiency ≥99.995% for 0.3micron particles ( Europe EN1822 standard ) providing strong filtration capability. The 2 HEPA filters are designed with the leakage resistance patent technology, ensuring the work area air cleanness at Class 5 (ISO14644.1 standard) . Therefore, it can provide the production in operated in clean environment. Optional U15 ULPA filter 99.9995% efficiency for partical size 0.12um.
Negative Pressure Protection
The work area is made of one piece of SUS304 plate without weld point, it supports the precisely controlled airflow forms to the biologically contaminated ducts and plenums under negative pressure or surrounded by negative pressure ducts and plenums. it reduce the contaminated air in work area to leakage to room and protects the operator in safety. Filtered air exhaust to room or outside.
Approximately 30% of the air in the common plenum is exhausted through the HEPA filter to the room. The contaminated air filtrated by H14 HEPA filter and becomes clean air into the room. Advanced airflow sensors have a known standard of deviation exceeding safe airflow requirements by biological safety cabinets.
Humanized design
1. 6mm front sash window adopts hanging lifting system (Imported from Japan) ,using spring to limit the sash glass height level at arbitrary positioning, and avoid sash glass drop down suddenly.
2. The interior work zone is made of one piece of SUS304 plate with round corner and no weld points, no leakage risk and easy for cleaning. The work zone is surrounded by negative pressure, ensuring the contaminated air not leak outside.
3. Worktable is made of SUS304 plate and can be taken out. It can be risen up by handle and support rode, convenient for cleaning.
4. The exterior is made of steel with sprayed powder, anti-bacteria and easy for cleaning.
5. The base stand is equipped with mobile castors and leveling feet.
Intelligent smartflow control system
1. Angled color LCD display is easy to read the BSC working status.
2. Display blower, LED light, UV light and socket works condition.
3. Display downflow velocity and inflow velocity, the velocity display accuracy is 0.001m/s, This is based on 2 independent sets of velocity sensors.
4. Display filter life in percentage, it reminds the user to in safe condition to operate the BSC and change the filter in time.
5. Display time it is easy to know the operation time.
6. Display UV timer.
7. The controller is with password protection, the unauthorized person can not adjust the operating parameters.
