Positive/Negative Ventilation
Cages WITH Locks
The Allentown P/NC IVC system allows users to select the pressure mode on the exhaust blower, and the entire rack of cages can run at either a positive or negative cage environment on the entire rack. Both supply and exhaust air are always HEPA filtered, for protection of animals and staff, in either operation mode. The rack is extremely sturdy, with typical Allentown workmanship and quality.

Airflow
In either positive
or negative operating mode, the
airflow will always follow the same path, eliminating
the risk of contamination. HEPA filtered supply air
is introduced to the cage through our unique air
distribution "bullet", providing an even, low velocity wash across the cage bottom. This maximizes the
drying effect upon the bedding without creating distress
to the animals, allowing extended change out intervals.
Exhaust air is then extracted through the spring loaded
exhaust port and into the aerodynamically designed
exhaust collection tube. Both the spring loaded
exhaust
port and the supply kup with the auto-closure channel
provide a closed system when the cage is removed from
the rack. The fully gasketed and sealed exhaust and supply
manifolds and plenums are typical Allentown workmanship.
Airflow loss is minimized,
creating the most air efficient system
for maximum filter life
and minimal energy consumption. However, the entire air
distribution system can still be fully accessed, without tools,
to allow thorough cleaning and inspection.
