Motorized door series:HFsafe-900(Class II Type A/ B3)
Vertical laminar airflow with negative pressure With a negative pressure in all ducts and plenum system, all particles will be returned to the negative pressure chamber and captured by main and exhaust filters even if a leak occurs in the sealing system.
ULPA filters It offers a filtration efficiency of 99.999% for the particle size of 0.1~0.2 um that may be attached by bacteria and microorganism.
Safe protection for sample, operator and environment Besides high performance ULPA filters, constant vertical air flows, negative pressure ducts, plenum system and multi-layer safety glass windows, the main filter extends over the entire working area and it is protected against damage by a steel grid. The equipment is working quietly (< 65 dB )
Easy to decontaminate and disinfect The working chamber of the Biology Safety Cabinet is easy to be cleaned and disinfected. The segmented stainless steel counter surface can be taken out for autoclaving. The front sliding window, which seals the working chamber, makes it possible to disinfect the equipment easily and to switch it off without danger. UV light can only be turned on when the front window is closed completely and the lighting lamp is turned off. It avoids the potential hazard to the operator from UV light.
Advanced microprocessor control system The control system measures the wind pressure accurately and balances the air speed profile strictly for entire working chamber. The unique advantage here is that the wind pressure difference before and after the filter is displayed by a strip bar on the LCD control panel. It works as an indicator of the product life of the filter, which reminds the user to exchange ULPA filters just on time.
Self-adjustment pressure system The vertical airflow will be automatically supplied at the speed of 0.4 m/s 20% without interruption. When filter block occurs, the fan motor will increase its speed to ensure constant vertical airflow to guarantee the safe performance.
Electricity-driven front window The front window is driven by a motor, and it can be moved smoothly and exactly to a desirable position. At its lowest position, it can completely seal the working chamber. If the opening position is higher than the safe position, an acoustic alarm will remind the user to adjust it.
Non-reflecting safety glass All the windows are made of multi-layer, non-reflecting safety glass (MSG) of the highest quality. A comfortable operation surrounding is offered to the operators.
