Animal Containment Workstation

The Portable Safety Solution for Animal Research Laboratories

Esco VIVA® Dual Access Animal Workstation (VDA) gives the best allergen, microbial, and product protection, at lowest energy consumption and noise, while giving the ultimate user comfort. Esco VDA operates at a low noise of 53 dBA which translates to operator comfort and prevents the lab animals from being agitated during cage transfer. Being the only cage transfer unit that has legroom on both sides, it allows two operators to work comfortably at the same time. VDA’s internal workzone is divided into 2 by an air curtain that allows transfer of the animals from a “dirty” to a “clean” area.

VDA Cabinet Airflow System

• The VDA Dual Access Workstation employs recirculating airflow configuration for better filtration efficiency
• The blower system pulls ambient intake air through the front grilles, creating inflow that provides operator protection from allergen inside the work zone. An activated carbon pre-filter removes odors.
•  Air flows through the common plenum on top of the cabinet. A portion of it goes up through ULPA filter as exhaust to create inflow. The remaining portion goes down through ULPA supply filter and bathes the work zone in clean air with a non- turbulent downflow
•  The combination of vertical laminar downflow and inflow creates an air curtain to protect the operator from contaminants released from the work surface.

VA2 Cabinet Airflow System

• Ambient air pulled through the perforations towards the work zone front prevents contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Inflow air travels through a return path toward the common air plenum (blower plenum) at the top of the cabinet.
  
•  Approximately 40% of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining 60% of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air stream bathing the work surface in clean air.
• The uniform, non-turbulent air stream protects against cross-contamination within and throughout the work area.
• Near the work surface, the ULPA-filtered downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the downflow enters the side capture zones at a higher velocity (small blue arrows).
• A combination of inflow and downflow air streams form an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.

VBD Cabinet Airflow System

• Room air is drawn in across the front of the cabinet with an average velocity of
  0.35 m/s (70 fpm).
• Air is drawn up through the cabinet's work zone and forced through the ULPA filter
  (>99.999% typical efficiency for 0.1 to 0.3 micron sized particles).
• The full work zone ceiling extraction system ensures airflow uniformity throughout the cabinet's main chamber.
• The ULPA filtered air then returns to the laboratory stripped of all airborne contaminants and odor.
