Smooth and easy sliding in, and the same sliding out...less stress and vibration for your animals and less repetitive motion strain on your staff... those are the benefits of NexGen's innovative plastic runner system. So innovative that the NexGen is changing the way animal care staff perform their wellness checks...they just slide their occupied cages out of their stalls 3/4 of the way and assess their animals. No need to fully remove cages from the rack...making animal observation simpler, easier and faster than ever before!

  • Positive locking & indication, one finger operation. CHECK THIS!
  • Easier, simpler and faster health checks
  • Animals experience much less vibration
  • More ergonomic, less strain for animal care staff
  • Polysulfone plastic, autoclavable
  • Reduced weight, improved functionality

Patented system of airflow at the cage level in NexGen: less ammonia and CO2 level


There's so little you'll hear when using a NexGen that it's easier to describe what you won't: no loud hum, no swirling fan, no air noise as it gets sucked into the blower intake...just quiet. Energy efficient ECM motors along with design expertise applied by Allentown airflow experts ensures you'll barely even notice that the blowers are on!

  • A little as 20 dBA. TURN ON your loudspeakers and compare the difference between EcoFlo and another blower:
  • As little as .15 watts per cage slot
  • WiVarium technology allowing blower control via iPad/Tablet
  • Vantage wireless rack monitoring capable
  • Factory certified HEPA blower assembly, not just the filter!
  • Smart blowers - Automatic filter load compensation/pressure polarity control/monitoring

Excellent functionality and maneuverability

  • Smart-engineered to be stronger while needing less structural support
  • Rivet technology coupled with high-strength, high-grade autoclavable plastic components
  • Streamlined assembly process improves cost and delivery times
  • Up to 25% lighter than other IVCs
  • No loose parts, easy prep for washing and autoclaving
  • Easy assembled caging systems with increased visibility
