NexGen Rat 900 IVC Rack

NexGen™ Rat 900 IVC Rack – Individually Ventilated Cage Rack for Rats

The NexGen™ Rat 900 IVC Rack is part of the Allentown NexGen™ IVC system, configured for rat housing. It accommodates 30 to 70 cages in 5 columns and 6 or 7 tiers, including reusable NexGen™ Rat 900 cages (with a floor space of 916 cm²) and single-use EasyCage® Rat cages. Single-sided racks can be placed against a wall, while double-sided racks are designed for freestanding placement in the room.

This version is designed for bottle watering: no water installation is required, so the rack can be positioned and moved freely. A version for automatic watering is also available.

Ventilation and Air Pressure

An EcoFlo™ blower delivers HEPA-filtered air to every cage at 60 air changes per hour (ACH). The rack can operate with positive cage pressure (protecting animals from the room environment) or negative cage pressure (protecting staff and the room from allergens), while the exhaust plenum always remains at negative pressure relative to the room. Blowers can be mounted on the rack or wall or configured as a tower serving several racks.

Available Configurations

Height includes casters. Add 247–297 mm for a rack-mounted blower. Dimensions may vary with optional bumpers.
