The AllerGard NU-620 Dual-Sided Animal Transfer Station enhances laboratory environments by providing a specialized animal care and research solution. Equipped with a DC impeller, it directly supplies the work zone with HEPA-filtered clean air, ensuring a clean environment for handling research animals. Simultaneously, a DC ECM motor beneath the work surface maintains a protective barrier against allergens by managing air removal. This precise airflow control is pivotal for safeguarding the research animals' health and the validity of experimental data. The dual-sided access of the NU-620 maximizes operational flexibility, especially in labs with limited space, promoting efficient workflows. NuAire's commitment to advancing research safety and efficiency is reflected in the design of the NU-620, making it an essential asset for vivariums prioritizing high cleanliness and animal welfare standards. *See last two photos for additional details
