Biological safety cabinets (BSCs) provide the primary source of containment for microbiological research. Laboratories that need containment and removal of vapors, mists and particulates will often choose a Class II, Type B2 total exhaust BSC (Type B2). Because this type of BSC must be totally exhausted to the outside through a facility’s HVAC system, it requires a great deal of energy to operate and can add significantly to a laboratory or facility’s operating costs.
According to an analysis published by the U.S. Environmental Protection Agency, laboratories consume 5 to 10 times more energy per square foot than typical office buildings.1 Access to more energy-efficient equipment, without any sacrifice in safety and performance, will allow labs to decrease not only energy consumption and operating costs, but also their environmental impact. The BioChemGARD® e3 total exhaust BSC from The Baker Company (Baker) is engineered to help achieve this.
With the BioChemGARD e3, a reduction in exhaust airflow and resistance cuts the electrical power, noise and static pressure requirements for the facility and reduces the volume of conditioned air exhausted from the laboratory. The nominal size 4-foot model operates at only 664 CFM and uses new, three-phase Variable Frequency Drive (VFD) motor technology to help deliver a reduction of up to 86% in electrical power when compared to traditional Type B2 total exhaust cabinets. This combination contributes to an overall reduction in the energy/power consumption requirements for most facility exhaust systems of up to 23%, providing a potential for annual operational cost savings of up to 49% over traditional Type B2 total exhaust cabinets listed with NSF International. Performance and productivity remain high, while protection for both the product and personnel exceed NSF International Standards #49.
