The AllerGard family of Animal Transfer Stations (ATS) borrows from NuAire&rsquo;s expertise in both containment and laminar airflow to provide optimal sterility for lab animals as well as robust allergen protection. All NuAire Animal Transfer Stations operate based on a &ldquo;push-pull&rdquo; concept wherein a supply motor above the work zone and an exhaust motor below together create a powerful &ldquo;piston of air.&rdquo;
