The HR1200-IIA2 double exhaust filtered biological safety cabinet utilises two highly efficient HEPA exhaust filters and one ULPA downflow filter to provide three levels of protection; operator, product and environment. As there is no need for external ducting, this is a cost- effective solution. The unit is certified to the EN 12469 standard. It uses energy efficient EC fans, as well as LED lights to ensure for optimal performance with a low noise output and reduced energy consumption. The ergonomic design ensures maximum comfort and alleviates operator fatigue. The units utilise side air design on the upper edge and on both sides of the front window to eliminate ‘blind spots’. This prevents crossflow between inside and outside air thus reducing the risk of contamination.
