PuriCare Procedure Stations provide personnel, animal and environmental protection. They are specialized Class II, Type A2 biosafety cabinets that create a particulate-free environment for conducting small animal research activities including cage changing, weighing, anesthesia delivery and surgical procedures.
During operation, room air is drawn into the grille located in the air foil and passes into a plenum located under the work surface. This inward airflow protects the operator by preventing the escape of particulates inside the enclosure. The blower draws the air from the work area through the back plenum of the enclosure, where approximately 70% of the air is recirculated through the supply HEPA filter and back over the work area. This HEPA filtered vertical laminar airflow provides ISO Class 5 conditions that protect the animals from environmental and cross-contamination. After passing through the exhaust HEPA filter to protect the environment from allergens, the balance of the air inside the enclosure is discharged to the room.
All models feature:
- Nominal inflow velocity of 105 feet per minute (fpm)
